Lifting weights, not rest: new study tests exercise as treatment for lost periods

This study looks at whether an 8-week supervised weightlifting program can help active women with functional hypothalamic amenorrhea (a condition where periods stop due to stress and low calorie intake) safely regain their menstrual cycles. Researchers will compare 28 women—some with the condition and some with normal cycles—tracking changes in strength, mood, and overall health. The goal is to offer an alternative to the usual advice of complete rest, which can be stressful for active women.
