What is the P90X Legs and Back workout routine?

The P90X Legs and Back workout routine is part of the P90X (Power 90 Extreme) program, designed by fitness guru Tony Horton. This particular session focuses on building strength and muscular endurance in the lower body and back through a series of challenging exercises. It typically includes compound movements and isolation exercises that target various muscle groups such as the quadriceps, hamstrings, calves, glutes, and all major muscles of the back. Exercises within the routine often involve lunges, squats, pull-ups, and deadlifts, among others. The workout is structured in an intense circuit format to improve not only muscular strength but also cardiovascular fitness, making it a comprehensive approach to physical conditioning. As with all P90X workouts, Legs and Back emphasizes proper form, versatility, and a gradual increase in intensity over time to maximize results.
