Instead, ask why.

For example:

If you can't climb stairs because your knees hurt, the issue may be joint health rather than cardiovascular fitness.

If you can't get up from a chair because your legs feel weak, strength training might be useful.

If you feel dizzy when standing, the issue may involve blood pressure, medications, dehydration, or another medical condition.

If you're afraid of falling, balance training and fall-prevention strategies may help.

If your ability has suddenly changed, medical evaluation is particularly important.

The most useful question isn't:

"Can I do this?"

It's:

"Has my ability changed, and why?"

When a Decline in Physical Ability Should Be Checked

A gradual decrease in strength can occur with aging.

But significant or rapid changes shouldn't automatically be dismissed as "just getting older."

Talk with a healthcare professional if you notice:

• Rapid loss of strength

• Repeated falls

• New difficulty walking

• Persistent dizziness

• Unexplained shortness of breath

• Chest discomfort during activity

• New muscle weakness

• Persistent numbness

• Difficulty getting out of a chair

• Unexplained weight loss

• Severe fatigue

• New problems with coordination

Sudden neurological symptoms require urgent attention.

For example, sudden weakness or numbness on one side of the body, facial drooping, difficulty speaking, sudden vision changes, or sudden loss of balance can be signs of a stroke.

Don't wait for such symptoms to disappear.

How to Protect Your Strength After 70

The good news is that aging doesn't mean you have to surrender your physical abilities.

There are practical ways to support mobility and independence.

1. Keep Moving

Avoid spending the entire day sitting.

Short walks throughout the day can be useful.

Even simple movement around the house contributes to your daily activity.

2. Include Strength Training

Muscle responds to resistance.

Depending on your abilities, two or more sessions per week of muscle-strengthening activity may be appropriate.

Start gradually.

3. Practice Balance

Simple balance exercises can be incorporated into a safe routine.

Always prioritize fall prevention.

4. Eat Enough Protein

Older adults need adequate protein to support muscle maintenance.

Protein-rich foods can include:

• Eggs

• Chicken

• Lean meat

• Fish

• Dairy products

• Beans

• Lentils

• Tofu

• Other protein-rich foods

Individual protein needs vary depending on body size, activity level, and medical conditions.

People with certain kidney conditions, for example, may need individualized dietary advice.

5. Get Enough Sleep

Sleep is important for recovery, energy, mood, and physical function.

Poor sleep can make exercise feel harder and may affect balance and concentration.

6. Stay Socially Active

Physical health isn't isolated from mental and social well-being.

Walking with friends, joining a community activity, participating in group exercise, or spending time with family can make staying active more enjoyable.

Don't Forget About Bone Health

Strong muscles are only part of maintaining mobility.

Bone health becomes increasingly important with age because bone density can decline.

Osteoporosis can develop without obvious symptoms until a fracture occurs.

Weight-bearing activity, resistance exercise, adequate nutrition, and appropriate medical screening can all play a role in maintaining skeletal health.

If you're at increased risk of osteoporosis, ask your healthcare professional whether bone-density screening is appropriate.

Your Feet Matter More Than You Think

Many people focus on their heart, lungs, and muscles but forget about their feet.

Healthy feet help you remain mobile.
