The Firm - Firm Parts: Tough Tape 2 [VHS]
Designed as a pair, FIRM Strength and FIRM Cardio cross train by varying the sequencing of exercises: FIRM Strength shapes muscles by first working the upper body, then the entire lower body, and FIRM cardio burns fat using PHA (Peripheral Heart Action) training to work the upper and lower body alternately.  PHA sequencing also strengthens the heart by repeatedly making it pump blood back and forth between distant muscle groups.  When used on alternate days they sculpt your body by preventing muscles from adapting to predictable exercise sequences, and maximize aerobic endurance and fat burning.  Each workout includes a tough abdominal section.  When used individually, each program provides a complete total body workout.
