The Firm: Volume 4: Time-Crunch WorkoutSusan Harris, Kai Soremekun
Year Released: 1990
Categories: Circuit Training (cardio and weights)
For a short 42 minutes, this workout backs a total body punch. There is just enough of everything to make sure the total body gets worked out, and this is the one that introduced the shorter box. Those climbs on the short box get my heart rate up. I skip the ankle weights for the standing leg work, and don't miss them when you add in all the lunges and squats. Definitely a keeper.
Susan is back for Volume 4, and newcomer Kai adds a nice touch.
