If you have blisters and other foot issues, it could be related to weak glutes. “A new blister could indicate a change in the gait of the runner, and it could be a sign of poor gait/biomechanics from glute weakness such as altered foot striker pattern,” says Bayes. (It’s worth mentioning, however, that this could also just be a sign of a sneaker problem, and you might just need to buy a better-fitting pair of shoes.)
Achy knees are often written off as an inevitable side effect of getting older. And while it’s true knee pain has many age-related causes (namely, arthritis), chances are weak glutes are a big part of the problem, Kline says. If you’ve been diagnosed with arthritis, strengthening your glutes can at least help offset some of the pain you might experience, she says.
