SHRED Fitness

Three well-structured aero/tone interval workouts.

These fast-paced exercises will keep you burning fat as you sculpt muscle.

The programs build in intensity; you can start with the intermediate level and work up to advanced movements.

Each workout has three “cycles.” Each cycle starts with multi-muscle and isolated strength training.

Then it’s time for non-dancy kickbox and athletic-style cardio that’s followed by classic abwork (then — no rest — you’ll immediately start a new cycle).

Requires 3 to 5 lb. weights
