It’s a workout methodology based on constantly-varied high intensity movements that help everyday life. Why it works is because your body never adapts to any one movement thereby keeping the effect of any given day’s workout at maximum – and you never gets bored. The intensity that everyone takes part in ends up galvanizing our supportive community.
Rest days rotate throughout the week for the multi-sport athlete, some weeks a full day of rest may be prescribed, other week, maybe not. Ultimately you’ll need to listen to your body. IF you need a rest day, take one. Pay attention to your energy levels and performances in your workouts. Schedule complete rest days as you need based on your performance level and energy levels throughout the day.
