100 Seconds is all it takes to push your lower body performance to a new level and the 100 Seconds workout promises to do just that up to seven times if you do it at Level III. This is a high-burn workout so you need to try and get as many reps in each segment of time as possible at every level. As a matter of fact you should count reps in the first set and then maintain the number throughout each set.
Extra Credit: Hit the same number of reps for jump squats and jumping lunges every time.
