Which exercise is best for irregular periods? For irregular periods, exercises that focus on stress reduction and overall well-being are beneficial. Yoga and Pilates promote relaxation and hormonal balance. Cardiovascular exercises like brisk walking or swimming can enhance circulation and potentially regulate menstrual cycles. Strength training exercises help stabilize hormone levels. However, avoid excessive or strenuous workouts that might disrupt menstruation, and consult a healthcare provider for personalized guidance if irregular periods persist.
