Separate lower and upper-body workouts that both use "trisets" — a proven technique that works each body part with a progression of three distinct exercises (e.g. legs: wall squats, front lunges and side squats). The upper-body program even adds a unique variation. It sequentially targets three related muscle groups (e.g. one exercise each for chest, shoulders and triceps). Cathe also boosts the challenge — and effectiveness — by repeating each three-exercise series at a higher intensity level (e.g. using heavier weights).

Note: While the workouts are body-part-targeted, the DVD's extensive premix selection includes lots of pre-programmed, upper/lower options.
