The Firm Cross Trainers - Firm Cardio(1995)

Sequenced to burn fat while working alternately upper and lower body.

The Firm Cross Trainers: Firm Cardio is a fitness workout designed to pair with its companion program for comprehensive body conditioning. This cardio-focused routine uses Peripheral Heart Action training, alternating upper and lower body exercises to maximize fat burning and aerobic endurance. By forcing your heart to pump blood between distant muscle groups, PHA sequencing strengthens cardiovascular fitness while preventing muscle adaptation. When alternated with The Firm Strength program on different days, the two workouts create a complete cross-training system that sculpts lean muscle and boosts calorie burn. The varied exercise sequencing keeps your body challenged and responsive, delivering results beyond what either program achieves alone.
