In women who are postmenopausal, not very active, and carry extra weight, having more muscle doesn’t always mean better blood sugar control — sometimes those with bigger muscles actually have worse insulin resistance.

In women who are overweight or obese after menopause, gaining muscle from exercise without cutting calories might actually make the body worse at handling blood sugar — so more muscle doesn’t always mean better health in this group.

Working out with weights can help older women build muscle and get stronger, no matter how exactly they do the workouts or which group they're in.

Skeletal muscle mass is a primary determinant of whole-body glucose disposal capacity, and higher muscle mass is inversely associated with visceral adipose accumulation via reduced insulin demand.
