Functional fitness: exercises that keep you strong and active
Full newsletter content: age-related body changes
As we age, our bodies go through changes that can affect strength, flexibility, and overall mobility, often starting earlier than expected. From muscle loss and reduced strength to declining balance and flexibility, these shifts can make everyday tasks more challenging.
While it's natural to experience these changes, they don't have to define your later years. Understanding the impact of aging on your body and incorporating functional training into your routine can help you stay strong, active, and independent. Here are some age-related changes to be aware of.
Muscles shrink. The newsletter says muscle loss begins in your mid-30s, at a rate of 1% to 2% a year. While that may not sound like much, these little changes make a difference over the years, contributing to achy joints, injuries, and weight gain - all of which can make daily activities more challenging. As you get into your 60s and 70s, muscle loss can accelerate to as much as 3% a year.
Strength wanes. One result of muscle loss is a decrease in strength, making activities like walking, getting out of a chair, and climbing stairs more difficult. The newsletter says that beginning in your mid-30s, you lose about 1.5% of your strength a year, and that rate accelerates as you get older. Some older adults lose as much as a third of their strength over a 10-year period.
Power declines. As muscles shrink, you lose not only strength but also power, your body's ability to exert force or strength quickly. Power plummets at more than twice the rate of strength - 3.5% a year for power compared to 1.5% for strength. Reductions in power make it harder to get across a street before the light changes, hoist a heavy bag of groceries, or catch yourself when you stumble.
Aerobic capacity decreases. The newsletter gives this comparison: a 25-year-old heart can pump 2.5 quarts of blood a minute; after age 30, heart and lung function begin to decline at about 10% per decade. Its comparison gives about 1.5 quarts a minute for a 65-year-old and about 1 quart for 80-year-olds. These are the newsletter's illustrative figures, not thresholds for assessing an individual's heart function. Such changes affect endurance.
Joints stiffen. A decrease in flexibility and range of motion makes tasks like reaching overhead and stooping down problematic. Nearly 20% of older adults have difficulty reaching something on a high shelf, while 51% are challenged when they drop something and have to bend down to pick it up. Flexibility in the hip and shoulder joints declines about 6° per decade from age 55 to 85.
Balance wobbles. According to a study in the British Journal of Sports Medicine , 54% of people in their early to mid-70s weren't able to balance on one leg for 10 seconds without holding on to something. As you become less steady on your feet, tasks like going downstairs, navigating around obstacles, and traversing uneven surfaces become more difficult, and you're more likely to fall.
Body fat increases. Even if the number on the scale isn't budging, you're probably gaining more fat as your muscles shrink. But if you're like most people, you're probably seeing an increase in your weight, too. That extra fat and weight can make it harder to get around and can tire you out faster. Extra layers of fat can also affect your ability to do things like bending over to tie your shoes.
Functional fitness is a powerful tool for maintaining strength, mobility, and independence as you age. By staying active and following safety guidelines, you can slow down some of these age-related changes and continue to enjoy a healthy, fulfilling lifestyle well into your later years.
Earlier published exercise guidance
Functional fitness means training your body for the movements of daily life - carrying groceries, climbing stairs, rising from a chair, lifting a grandchild - so you stay strong and independent as you age.
Unlike exercises that isolate a single muscle, functional exercises work several muscle groups at once and mimic real-world patterns: pushing, pulling, squatting, lifting, and rotating.
Squats are a foundation. They strengthen the legs and core you use every time you sit down and stand up. Start by rising from a chair without using your hands, then progress to deeper squats as you get stronger.
Lunges build balance and one-legged strength, which you rely on when walking, climbing stairs, and stepping over obstacles.
Push-ups - against a wall, on a countertop, or on the floor - develop the pushing strength used to open doors and get up from the ground.
Rows, done with a resistance band or light weights, strengthen the back and arms for pulling movements like opening a heavy door or starting a lawn mower.
Carrying exercises are as simple as they sound: hold weights at your sides and walk. They build grip strength, core stability, and the ability to haul groceries or luggage.
Balance work - standing on one foot, heel-to-toe walking - rounds out a functional routine and reduces fall risk, one of the biggest threats to independence with age.
Aim for two or three sessions a week, with moves that feel challenging but doable. The payoff is practical: everyday tasks stay easy, and you keep doing the things you love.
Before starting any new exercise program, check with your doctor, especially if you have a chronic condition or have been inactive.
