4 Week FULL body workout program workouts! Suitable for intermediate exercisers. This phase is called Pre-Exhaust. Pre-exhaust is pre-fatiguing the muscle. It consists of using an isolation or “single-joint” exercise first, and then finishing with one or two compound or “multiple-joint” movement(s). Utilizing two single joint exercises followed by a multiple-joint movement is typically referred to as a “double-pre-exhaust”. The idea/reason for pre-exhaust training is that it is a method that forces your muscles to work twice as hard on compound movements ensuring muscular fatigue first before mental fatigue sets in. Great for Women or men!
