Here is my 4 day rotation:
Mon-High Step Circuit
Tues-Push Pull
Weds-rest
Thurs-Boot Camp
Fri-Muscle Endurance
I use only light weights on the cirucit training days of mon and thursday and concentrate on making them cardio workouts. But I feel like I'm getting a better muscle workout using weights 4 days a week instead of only 2. I really like this rotation. Here are some substitutes:
Mon/Thurs circuit: High Step Advanced, Circuit Max, Cardio Weights, Step, Jump, Pump, Gauntlet, Viper, Body Fusion, Power Circuit (from CTX), Body Max, old Firm videos or Fitprimes.
Tues/Fri weights-any of Cathe's total body weight workouts.
I like this rotation becuase I use Saturday for a hiking day or catch-up day if I missed a workout, and then rest completely on Sunday.
