P.Volve Is Launching a New Workout Program Inspired by Your Menstrual Cycle For those unfamiliar with the concept of coordinating your workouts with your menstrual cycle, it typically entails picking workouts that cater to hormonal fluctuations and the symptoms your body is experiencing during specific phases of the menstrual cycle. Some experts say this, in turn, may yield a more effective exercise routine. Not sure how to get started on that? A new customizable online health and fitness program from P.volve (a functional fitness method that prioritizes low-impact, dynamic joint movements) dubbed Phase and Function seeks to make the process of pairing your workouts with your cycle a little easier while soothing physical symptoms and still delivering results along the way.
