Answering what is turning into an evergreen question related to aging well, lifting weights.
How heavy do you really need to lift to build muscle after 50? If you've been told you have to lift as heavy as possible, you know that the words lift heavy, you know what? I've got a study I want you to hear about.
If you've been using the same light dumbbells for years, stay with me because this doesn't mean you can stop progressing, but...
it might mean you want to pay a little bit more attention to what happens within that set.
This research that I'm reviewing was published in 2026 in Experimental Gerontology.
Researchers compared training with a weight they could lift about 10 times with a weight that they could lift about 15 times.
Researchers wanted to know whether the heavier option would produce more muscle growth.
27, this is not a big study, 27 women completed two eight-week resistance training periods.
Once they completed the first eight weeks, 10 repetition maximum, meaning they couldn't do any more than 10. and one at a 15 repetition maximum in randomized order.
There was a 12-week period without training between, so we kind of cleaned the slate, right? RM, by the way, means repetition maximum.
Now, if you and I rest for a minute, we're going to be able to pick that weight up again, but it is temporary failure.
15 repetition maximum is obviously a lighter weight, but it's still challenging resistance at the end because the end point of those sets, what they call the top number, the either ninth or 10th or the 14th, 15th were challenging.
