The quads, glutes and abs are amongst the body's strongest muscle groups which means that when they work they use up a lot of oxygen. Oxygen being used up burns calories and test your VO2 Max fitness. Trimmer is a high-burn workout that requires you to bring your knees up to waist height every time, in every exercise without exception. The results are not just in sweat shed and calories burnt but also in tendon strength gained, aerobic fitness improved and muscles conditioned. Add EC and it becomes extra hard.
Extra Credit: 1 minute rest between sets.
