Mastering Your Fitness Routine: Simple Ways to Meet WHO & CDC Exercise Guidelines at Any Age

Written by: Dr. Katie Wadland, PT, DPT, Board-Certified Geriatric Clinical Specialist and Owner of Healthy Aging PT

We all know the importance of regular exercise, but fitting it into your lifestyle can sometimes feel overwhelming. The World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) recommend that adults aim for 150 minutes of moderate-intensity aerobic activity combined with 2-3 days of strength training per week, along with balance and flexibility exercises. However, not everyone starts at the same fitness level or has the same lifestyle, so learning to adapt these guidelines to suit your life is key.

What Are the WHO and CDC Guidelines?

The basic recommendations for adults include:

• 150 minutes of moderate-intensity aerobic activity (like brisk walking) or 75 minutes of vigorous-intensity activity (like running) per week.

• 2-3 days of muscle-strengthening activities (targeting major muscle groups) per week.

• Balance and flexibility exercises, especially for older adults, to help prevent falls and maintain mobility.

Reality Check: How Much Are We Actually Exercising?

Surveys show that a majority of adults aren’t meeting these guidelines. According to the CDC, only about 23% of American adults get the recommended amount of both aerobic and muscle-strengthening exercise. Meanwhile, physical inactivity is linked to chronic illnesses such as heart disease, diabetes, obesity, and depression.

The good news is that even small changes in your weekly activity can have a significant impact on your health.

The Benefits of Regular Exercise

Exercise isn’t just about maintaining a healthy weight—it has wide-ranging benefits for both physical and mental health. Regular physical activity:

• Reduces the risk of chronic diseases

• Helps control weight

• Strengthens bones and muscles

• Improves mental health and mood

• Increases your chances of living longer

On the flip side, physical inactivity can lead to higher rates of heart disease, stroke, diabetes, and some cancers. It's clear that staying active is one of the most important things you can do for your health.

What a Balanced Exercise Week Looks Like for Me

Let’s talk about how I fit exercise into my week as an example of how to meet the guidelines. My routine is built around balance, consistency, and flexibility:

• Aerobic Exercise: Three days a week at my local gym, I aim for 30 minutes on the elliptical, treadmill, bike, or rower. Sometimes I do intervals, mixing short bursts of higher intensity with recovery periods. Other times, I do steady-state cardio. My goal is always to hit 30 minutes of aerobic exercise per session, which helps me meet the CDC's weekly guideline.

• Strength Training: I lift three days a week. One day is focused on legs, one on upper body, and the third is a full-body workout. I also mix in core exercises throughout the week. This keeps my strength routine varied and helps me hit the goal of 2-3 days of muscle-strengthening activities.

• Flexibility and Balance: On either Saturday or Sunday, I incorporate yoga into my routine. It’s my way of improving flexibility and balance, which is a key component of the guidelines, especially for preventing falls as we age.

• Active Lifestyle: In addition to structured exercise, I like to stay active on my "rest" days by taking a small hike with my kids, mowing the lawn, or doing housework. These activities add to my overall activity level without feeling like a formal workout.

I also teach fitness classes during the week. While I consider these part of my active lifestyle, I don’t count them toward my personal exercise goals because they’re more about helping others increase their baseline activity levels.

Example 2: An Older, Moderately Active Adult

Let’s say you’re an older adult who is still fairly active but may not want or need to hit the gym as often. Here’s how you can structure your week:

• Aerobic Activity: This person could take outdoor walks five times a week for 20-30 minutes each session. That would total 100-150 minutes of moderate-intensity activity for the week.

• Strength Training: Twice a week, they could join a strength training class at their local senior center or gym. There are also great online programs, such as our Club HAPT, that offer guided strength workouts for home use.

• Balance and Flexibility: Mixing in something like Tai Chi or yoga once or twice a week can help maintain balance and flexibility, key elements to prevent falls and stay mobile. Our balance programs can also be done at home to support long-term health.

• Active Lifestyle: In addition to structured exercise, they can incorporate more movement into their daily life by parking further from the store, taking the stairs instead of the elevator, or working outside in the yard. These activities help add to overall activity levels and make it easier to meet the weekly exercise guidelines.

This routine is perfect for maintaining a healthy lifestyle and preventing the decline in muscle mass and balance that can occur with aging. There are also videos available on our Balance and Falls page that offer great exercises that can be done at home to improve stability.

Example 3: A Lower-Level, Sedentary Adult

For someone who is less active or has mobility challenges, it’s still important to find ways to incorporate movement into their week. Here’s how someone at a lower fitness level can meet the exercise recommendations:

• Aerobic Activity: A seated recumbent elliptical like the Cubii can provide low-impact aerobic exercise. Walking in a mall with a walker or doing an aerobic workout on YouTube can also be effective.

• Strength Training: Functional strength training doesn’t have to happen in a gym. Simple movements done in the kitchen or living room—such as sitting and standing from a chair—can provide the necessary strength training. These activities mimic the kinds of things we do during physical therapy and can be scaled to any ability level.

• Balance and Mobility: Balance exercises, such as those done in therapy, can be adapted for home use. Programs like PWR! Moves for Parkinson’s Disease are great for adding in mobility work that supports overall health.

• Active Lifestyle: For someone at a lower activity level, small bursts of movement—sometimes called "exercise snacks"—can be an easy way to build up daily activity. For example, they can march in place during commercial breaks, take an extra lap each time they go to the bathroom, or do 10 sit-to-stands every time they get out of a chair. These small actions add up and help improve overall mobility and strength.

Conclusion: Adapting Exercise to Your Life

No matter where you’re starting from, there are ways to meet the CDC and WHO exercise guidelines that suit your fitness level and lifestyle. Whether you’re hitting the gym, walking around your neighborhood, or working out at home, finding a balance between aerobic, strength, balance, and flexibility exercises is key to maintaining your health as you age. For help creating a personalized plan, you can use tools like the Move Your Way Activity Planner or join us at one of our Group Fitness Classes to get a great mix of everything combined. The most important takeaway is that every little bit helps, and even small steps toward being more active can lead to big health benefits.

Exercise Intensity and Older Adults: Finding the Balance

Written By: Dr. Brittany Saia, PT, DPT, GCS and Healthy Aging Physical Therapist

You’ve done it! You started your exercise routine and you’re sticking with it (well, most of the time.) But are you getting the most out of yourself and the full impact that exercise can achieve? In this post, we’ll discuss exercise intensity, and if it’s safe when considering exercise in older adults.

The Changing Landscape of Aging

Aging brings about various physiological changes, including a decline in muscle mass, bone density, cardiovascular function, and metabolism. As a result, older adults are more susceptible to issues such as sarcopenia (muscle loss), osteoporosis (brittle bones), cardiovascular diseases, and metabolic disorders like diabetes. However, regular exercise has been shown to mitigate these age-related declines and improve overall health outcomes.

Understanding Exercise Intensity

Exercise intensity refers to the level of exertion during physical activity. It's commonly measured using parameters such as heart rate, perceived exertion, or metabolic equivalents (METs). For older adults, exercise intensity plays a crucial role in achieving desired health benefits. While low-intensity activities like walking or gentle yoga provide some benefits, higher-intensity exercises offer additional advantages that are particularly valuable for older adults.

Benefits of High-Intensity Exercise for Older Adults

1. Muscle Strength and Mass: High-intensity resistance training stimulates muscle growth and enhances strength, which is vital for maintaining mobility and independence as we age. Strong muscles also help support joints and reduce the risk of falls and fractures.

2. Bone Health: Weight-bearing and high-impact exercises promote bone density, reducing the risk of osteoporosis and fractures. Activities like jumping, running, or strength training with weights can help preserve bone health in older adults.

3. Cardiovascular Fitness: High-intensity aerobic exercises, such as cycling,

   swimming, or interval training, improve cardiovascular function, lower blood

   pressure, and enhance circulation. A robust cardiovascular system is essential for maintaining overall vitality and reducing the risk of heart disease.

4. Metabolic Health: High-intensity interval training (HIIT) and vigorous aerobic

   activities can improve insulin sensitivity, glucose regulation, and metabolic rate, thereby reducing the risk of type 2 diabetes and obesity-related complications.

5. Cognitive Function: Emerging research suggests that high-intensity exercise may benefit cognitive health by promoting neuroplasticity, improving brain function, and reducing the risk of cognitive decline and dementia.

Finding the Right Balance

While high-intensity exercise offers numerous benefits, it's essential to strike a balance and consider individual fitness levels, health conditions, and preferences. Older adults should consult with a physical therapist a PCP before starting any new exercise program, especially if they have pre-existing medical conditions or concerns.

Incorporating High-Intensity Exercise into Your Routine

1. Start Slow: Begin with low to moderate-intensity exercises and gradually increase the intensity as your fitness improves. Especially if you’re new to exercise, starting slow can help prevent overly sore muscles and help build confidence in your abilities.

2. Mix It Up: Incorporate a variety of activities, including strength training, aerobic exercises, and balance exercises, to target different aspects of fitness.

3. Interval Training: Incorporate intervals of higher intensity into your workouts,

   alternating between bursts of intense activity and periods of rest or lower

   intensity.

4. Listen to Your Body: Pay attention to how your body responds to exercise and adjust the intensity accordingly. It's essential to challenge yourself while also respecting your limits and avoiding overexertion.

5. Stay Consistent: Consistency is key to reaping the benefits of exercise. Aim for at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity exercise per week, spread across multiple days.

Embracing the Power of Exercise Intensity

In conclusion, exercise intensity is a critical factor in promoting health, vitality, and longevity in older adults. By incorporating high-intensity exercise into their fitness routine, older adults can enhance muscle strength, bone density, cardiovascular fitness, metabolic health, and cognitive function. However, it's essential to approach high-intensity exercise with caution, gradually increasing intensity and listening to your body's signals. With the right balance and guidance, older adults can harness the power of exercise intensity to thrive in their later years.

Essential Summer Exercise Tips for Older Adults: Stay Safe and Healthy in the Heat

Written By: Dr. Allison Leonard, PT, DPT and Healthy Aging Physical Therapist

With summer heat here to stay, it’s crucial to be prepared to avoid heat-related illnesses, especially for older adults. As we age, our bodies become more susceptible to dehydration and injury, making it important to take extra precautions when exercising in hot weather. Older adults may have a diminished sense of thirst, reduced sweat production, and often take medications that can affect hydration levels. Additionally, the body’s ability to regulate temperature decreases with age, increasing the risk of heat-related issues. To help you stay safe and active this summer, here are some valuable tips to keep in mind:

1. Exercise Early or Late: Schedule your workouts during the cooler parts of the day, such as early morning or late evening.

2. Stay Hydrated: Drink plenty of water before, during, and after your workout. Avoid alcohol and caffeinated drinks as they can dehydrate you.

3. Wear Lightweight Clothing: Choose loose-fitting, light-colored, and breathable clothing to help keep your body cool.

4. Use Sunscreen: Apply a broad-spectrum sunscreen with at least SPF 30 to protect your skin from harmful UV rays.

5. Take It Indoors: Consider indoor alternatives such as gyms, swimming pools, or home workouts. Indoor malls, big box stores like Target or Costco are great options for getting in your steps.

6. Lower the Intensity: Reduce the intensity of your workout to avoid overheating. Listen to your body and take breaks as needed. Use less weight/resistance, shorter periods of exercise and longer rest periods.

7. Acclimate Gradually: If you're not used to the heat, gradually increase the duration and intensity of your outdoor workouts over a week or two.

8. Know the Signs of Heat Exhaustion: Be aware of symptoms like dizziness, headache, nausea, excessive sweating, and rapid heartbeat. If you experience any of these, stop exercising, move to a cooler place, and hydrate.

9. Cool Down Effectively: Use cooling towels, take cold showers, or apply ice packs to lower your body temperature after exercising.

By following these guidelines, you can stay active and healthy even during periods of extreme heat. Stay cool AND stay active!

Enjoy Summer WITHOUT Back Pain: Effective Strategies to Reduce Back Pain in Older Adults

Written By: Dr. Tracey Berman, PT, DPT and Healthy Aging Physical Therapist

It is a beautiful summer day, and you bend over to grab your bag to go to the beach. Suddenly, ouch! You feel pain in your lower back. Back pain is never fun to deal with and can put a damper on your summer plans. But remember, you are not alone. According to the National Institute of Health, back pain is one of the most common reasons people visit their doctors. As we age, various factors can contribute to back pain. Sometimes it is muscular, and sometimes it is structural. Finding the cause of your back pain can direct your course of treatment, and most treatments will involve some type of therapeutic exercise.

Understanding the Causes of Back Pain in Older Adults

Osteoarthritis: A Common Structural Cause

As we age, one of the structural causes of back pain is osteoarthritis. This is the breakdown of cartilage, the tissue that covers the ends of bones where they form a joint. When this tissue breaks down, bones are left unprotected and rub together, causing inflammation and pain. Osteoarthritis can also narrow the small holes that direct the nerves of the spine, often resulting in tingling, numbness, and pain that can radiate down your leg, commonly known as sciatica.

Osteoporosis: Loss of Bone Mass

Another reason for back pain as we age is osteoporosis, or the loss of bone mass. Your vertebrae can weaken to the point that you lose height, develop a hunched posture, and experience back pain. In some cases, this weakening can lead to fractures in the vertebrae, which can be quite painful.

Muscular Changes and Their Impact on Back Pain

Decreased Flexibility

Flexibility, or how limber you are, diminishes as we go through life. Normal aging involves a loss of collagen, which increases stiffness in our spine and joints and reduces the elasticity of muscles and tendons. This stiffness can make us want to move less because some motions cause pain, creating a cycle of moving less and becoming stiffer.

Sarcopenia: Loss of Muscle Mass

Sarcopenia, the loss of muscle mass and strength, can begin as early as your 30s. Physically inactive people can lose as much as 3% to 5% of their muscle mass each decade after age 30. Weaker muscles make you more prone to injuries like back sprains and strains.

How Back Pain Affects Daily Activities

Back pain can significantly impact how we move throughout the day, interfering with activities like standing in line at the grocery store, sitting to watch TV, reaching up in cupboards, climbing stairs, or picking up grandchildren. This pain can cause us to move less to avoid discomfort, but sometimes movement can actually help reduce pain by increasing blood flow and fighting inflammation.

The Role of Exercise in Reducing Back Pain

Aerobic Exercise

Walking is a fabulous low-impact aerobic exercise that can help reduce back pain. Swimming and cycling, whether on the road or a stationary bike, are also excellent options. Aerobic exercise promotes blood flow, bringing nutrients to the spine and boosting endorphins, the body’s natural painkillers.

Strength Training

Strength training builds muscle strength and doesn’t require a gym membership or heavy weights. Your physical therapist can guide you through appropriate strength training exercises using body weight, resistance bands, and light weights. Strengthening your core muscles is crucial for protecting your spine. Core muscles include your obliques, transverse abdominals, and rectus abdominals, which form a “corset-like” support for your spine.

Stretching

Stretching improves flexibility and can alleviate pressure on joints, especially for those with osteoarthritis. Incorporating yoga poses like child’s pose and cat-cow, along with static stretching routines for your hamstrings, hip flexors, and trunk muscles, can be beneficial.

Balance and Stability Exercises

Balance exercises, such as standing on one leg or walking with slow head movements, activate the small postural muscles in your back that help you stay upright. Stronger postural muscles provide more support for your back, reducing pain. Tai Chi is an excellent exercise for improving balance and incorporating deep breathing, which helps decrease muscle tension.

Starting an Exercise Program Safely

Getting Started

First, get medical clearance from your doctor before starting any exercise program if you have any unstable medical conditions or other health concerns. Start slowly and for short periods, keeping a journal to track your progress. Listen to your body and recognize signs of overexertion, such as fast breathing, dizziness, or chest pain. Warm up before exercising, and cool down afterward to allow your heart rate and blood pressure to return to pre-exercise levels.

Avoiding Common Mistakes

Proper technique and form are crucial to prevent injury. Avoid bouncing in a position, ignoring your limitations, and lifting weights that are too heavy. Consult a physical therapist or reputable instructional videos for guidance.

Diet and Sleep: Supporting Your Back Health

Maintaining a Healthy Weight

Carrying excess weight can strain your back. Aim to maintain a healthy weight through a balanced diet and regular exercise. Incorporate anti-inflammatory foods like tomatoes, olive oil, green leafy vegetables, nuts, fatty fish, and fruits such as strawberries and blueberries. The Mediterranean diet is a great example of an anti-inflammatory diet.

Proper Sleep Positions

Supporting your back during sleep is crucial. If you’re a side sleeper, place a pillow between your legs to keep your spine aligned. If you sleep on your back, place a pillow under your knees to relax your back muscles. Try to avoid sleeping on your stomach, but if you must, place a pillow under your hips to reduce strain on your back.

Back pain doesn’t have to ruin your summer plans. By understanding the causes and implementing a comprehensive management plan that includes exercise, diet, sleep, and other pain management tools, you can ease the pain and enjoy your favorite summer activities. Talk to a physical therapist to develop a personalized plan to keep your back healthy and pain-free.

Staying Hydrated: A Vital Guide for Older Adults During the Summer Heat

While it may be ‘hot girl summer’ everywhere else you look, here over at Healthy Aging, we’re entering ‘hot patient summer’ season. Last week, as temperatures climbed, I challenged my Parkinson’s class to a drinking contest - except instead of chugging beers, we tried to finish a bottle of water between exercises. While for most people, summer heat brings thoughts of bathing suits, pool parties and barbeques, for me, and most of my home health colleagues, we go to thoughts of dehydration, low blood pressures and passing out. So, as the summer heat approaches, I want to talk to you today about staying hydrated. Hydration over the summer is crucial for everyone, but especially older adults. Dehydration can lead to serious health complications, but with a few simple strategies, it’s easy to stay hydrated and healthy throughout the season. 

Why Are Older Adults More Prone to Dehydration?

Several factors make older adults more susceptible to dehydration. Older adults tend to have a reduced thirst sensation combined with lower kidney function. With aging kidneys becoming less efficient at conserving water, while we lose more water, we also have less drive to replace it. Older adults also often take medications that impact hydration like diuretics that lead to increased urination, or anticholinergic drugs that lead to reduced sweat production. Many older adults have mobility limitations, and try to avoid the ‘extra walks’ or nighttime waking to use the bathroom that they fear may come with increased hydration. Lastly, you may also notice that you sweat less when you get older. It’s not all in your head! Older adults sweat less as they age due to reduced sweat gland function and impaired thermoregulation - this means that on top of reduced hydration, they are less able to internally cool themselves down! All these factors combined make dehydration one of the most common causes for hospitalizations in older adults - especially in the summer months.

How do I know if I’m dehydrated?

While younger adults may be able to quickly identify the signs of worsening dehydration and take quick action, the signs in older adults can be a little tricker, often leading to delayed treatment. The most common signs we see when we suspect a patient may be dehydrated are dizziness, especially when coming to stand, and confusion. Orthostatic hypotension, a drop in blood pressure related to changing position when coming from laying down to sitting, or from sitting to standing, can happen at any time, but dehydration can make this worse. Confusion or irritability, or any other changes in mental status can also be a confusing symptom especially in an older adult who may already have some form of dementia, but look for worsening confusion from their norm. Other common signs of dehydration in older adults include reduced urine output, increased muscle cramping, dry skin and a rapid heart beat.

How do I prevent dehydration?

The easiest way to treat dehydration is to PREVENT IT! Try to drink 8 glasses of water a day, choose fluid-rich fruits like watermelon and oranges, veggies like cucumbers and other foods like soup and smoothies that can give you a little extra hydration throughout the day. Keep an eye on drinks that make you LOSE fluid and avoid excessive caffeine, soda and alcohol - or at least pair them with a glass of water to off-set the fluid loss. Stay cool by dressing in light, ‘flowy’ clothes and carry a bottle of water with you wherever you go to sip on throughout the day. Try to drink BEFORE you feel thirsty, even if it’s just a few sips at a time. Prevention can make a world of difference.

How do I treat dehydration?

If you are already feeling the signs of dehydration, don’t panic! Try to move to somewhere cool and rehydrate. Rest for 30-60 minutes and see if you start to feel better. If the symptoms don’t improve, or you experience any fainting, fevers, changes in heart rate or chest pain, nausea, vomiting or diarrhea, it’s time to get some help. Call your PCP for further instruction or go to your local urgent care or emergency department. While mild dehydration may be easy to treat at home, severe or ongoing dehydration can lead to serious medical complications like kidney failure, urinary tract infections and heat stroke. The faster you get the proper care, the better!

Challenge a friend to a drinking contest!

Now that you know the signs, symptoms and treatment of dehydration - let’s have some fun. Challenge the next person (or patient) you see to a drinking contest! Suggest you both take sips of water between conversation, exercises or along a walk and see who can empty their bottles first. Try flavoring water with hydration tabs or fresh fruit or make it fun by using a special glass, straw or turning it into a summer mocktail. Want a fun recipe to try? Here’s my favorite thirst-quenching mocktail: Fill half your glass with coconut water, and top it off with a flavored seltzer or fruit juice. The cool coconut flavors will take you to a warm, sandy beach in your mind - and your body will be hydrated. Win-win:)
