Question 4 of 45

Why am I losing muscle and strength?

Short answer

  • Estrogen helps muscles stay strong. When it drops, muscle can fade faster.
  • Studies show lean (muscle) mass goes down across the menopause transition.
  • Losing too much muscle and strength with age has a name: sarcopenia.
  • The good news: research shows women of all ages can build strength.

What to look out for

  • Trouble opening jars, carrying groceries or getting up from a chair.
  • Feeling less steady on stairs.
  • Workouts that feel harder for no clear reason.

Top 3 things to act on or ask your clinician

  1. Ask: 'Can we check my grip strength or muscle level?'
  2. Ask for a referral to a qualified trainer or physical therapist for a safe plan.
  3. Ask: 'Is anything in my health history a reason to be careful with lifting?'

Question 5 of 45

Is lifting weights safe for women after menopause?

Short answer

  • For most women, guided strength training is considered safe and helpful.
  • In one trial (LIFTMOR), women with low bone mass did supervised heavy lifting and gained bone and strength, without more injuries.
  • U.S. activity guidelines say adults should do muscle-strengthening activity at least 2 days a week.
  • Start where you are. Good form and good coaching matter.

What to look out for

  • Pain, dizziness or joint trouble when you exercise.
  • Known osteoporosis, past fractures or back problems.
  • Pushing too hard too fast.

Top 3 things to act on or ask your clinician

  1. Ask: 'Is strength training right for me, given my bones and joints?'
  2. Ask: 'Should I have a bone density test before I start?'
  3. Ask for a referral to a professional who works with women in midlife.

Question 6 of 45

Why does muscle matter for my metabolism?

Short answer

  • Muscle is where your body stores and uses much of the sugar from food.
  • More muscle helps your body handle blood sugar better.
  • Muscle also helps protect balance, bones and independence as we age.
  • Experts call muscle an 'organ of longevity.' The research on strength and healthy aging supports this idea.

What to look out for

  • Blood sugar creeping up over the years.
  • Sitting most of the day.
  • Strength going down from year to year.

Top 3 things to act on or ask your clinician

  1. Ask: 'How does my muscle level affect my blood sugar?'
  2. Ask: 'What kind of movement fits my health right now?'
  3. Ask: 'Can we track strength as a health marker?'
