The Level 2 routines are more challenging than those for Level 1 and include plyometrics (jump training), frequent elevation changes, and an increased level of difficulty.

Level 2 routines range from 5 minutes to 40 minutes in length, with work-to-rest ratios between 2:1 and 4:1. Consider incorporating the shorter routines into a longer workout as a metabolic-boosting “finisher.”
