Some workouts make you sweat and some others get you started on the journey to forge yourself into the best version of you, you can be. The Forge workout is definitely one of the latter. Combining fast moving cardio exercises with body combat moves it tasks major muscle groups to move gracefully, under pressure. Add some solid core work and an eccentric/isometric challenge at the end and you end up with a great way to shape your body in the way you want it to.
Extra Credit: 30 seconds rest between sets.
