Build the internal heat with this opening sequence meant to prepare your muscles for the bursts ahead.
Rapid heart rate bursts will bring your cardio to the next level. There is nothing more effective in terms of calorie burn and heart training than intense intervals of work and short periods of rest.
The best way to find your abdominal muscles is to burn the fat. The interval training will push that and then the extra ab work will tone and tighten!
Every workout - especially one that works to fatigue and build long lean muscle needs an ending stretch. Be prepared to enjoy!
