This 40 minutes High-Octane Shirt-Drenching workout will improve both strength and muscular endurance, increase cardio respiratory endurance, jump-start the metabolism and change the body composition as well as improve flexibility and the postural alignment. It's time efficient, burns fat, and strengthens the body safely and quickly. In addition, this intense workout allows you to stay focused and get the most out of every minute.

"Knowing that you only have 40 minutes helps you stay focused. With no time limit, I've noticed that our minds often stray while sitting on the Proformer™ in between sets. And before we know it, several minutes could have passed. Let's take that wasted time and put it back into the workout!" Says fitness visionary, Sebastien Lagree.

Our bodies are responsive to exercise on a continuum, not on a time-based threshold. An effective workout can be had in any amount of time, given how you manipulate the variables of the workout. People don't need more time, they just need more intensity!

The body responds more to intensity than it does to the duration of a workout. A more intense workout burns more calories per minute, and will result in a much stronger post-exercise reaction (also called Post Cardio Effect.) That's right, after an SPX class, your will continue to burn calories at a rate of a third more calories than during the workout-and this goes on for hours!!
