You show up. You go to yoga, Pilates or a group weights class every week, and you work hard while you’re there.
But you’re not getting any stronger, and it doesn’t make sense.
Your effort isn’t the problem. The resistance stopped changing.
Key Takeaways
- Being active and being loaded enough to get stronger are two different things.
- Your muscle responds to resistance that’s “appropriately challenging” for the strength you have today, and that resistance has to go up as you get stronger.
- Light versus “heavy” is the wrong argument, because sets of 15 and sets of 10 built similar muscle in older women when each set was the most they could do.
- Menopause doesn’t stop you from getting stronger, and in research, postmenopausal women gained strength as much as younger women.

Why Aren’t You Getting Stronger If You Already Exercise?
You probably measure your exercise by how much you do. You count how many days you go, how long you stay and how tired you feel afterward.
Your muscle responds to something else: resistance that’s high enough to make it adapt.
So you can go every week, work hard and still use dumbbells your body adapted to a long time ago. Those dumbbells no longer give your muscle a reason to change.
Your motivation is fine. Underloading is the single most common mistake Stephen sees.
What Your Muscle Actually Responds To
Your muscle responds to resistance that’s “appropriately challenging” for the strength you have today.
Then the resistance has to keep up with you. The weight goes up as tolerated while you get stronger.
That second part is the one most programs miss. A weight that was “appropriately challenging” a year ago probably isn’t anymore.
Does It Matter if the Weight Is Light or “Heavy”?
It matters less than you’d think. The argument about light versus “heavy” misses what actually matters.
One trial compared two rep ranges head to head:
Ribeiro AS et al., Experimental Gerontology, 2026. PMID 42551773.
The rep count wasn’t the deciding factor. Both sets worked because both were the most those women could do for that count.
So a lighter weight can build muscle too. What doesn’t work is a weight that stopped being challenging for you months ago.
Why a Class Can’t Keep Up With You
Yoga, Pilates and group weights classes are fine. They keep you moving, and they can build some strength.
But a class is planned for a room full of people. The instructor can’t set the resistance for your strength, and can’t raise it for you when you’re ready.
So the class stays the same, and after a while, so do you.
Is It Too Late After Menopause?
You may assume it is. An analysis of 126 studies found otherwise:
Isenmann E et al., Journal of Science and Medicine in Sport, 2026. PMID 41963141.
Menopause changes a lot of things. Your ability to get stronger isn’t one of them.
