About this project

Starting at only $35.

“Not only will your body burn more calories during high-Intensity Interval workouts but you will also continue to burn more calories and fat in the 24 hours after a workout.”- Kurt Hester, TD1 National Director of Performance, Mens Fitness


“Short rest periods also cause other muscle-building bonuses like increased lactate production and blood flow to the targeted muscles” -Kraemer, 1997; Kraemer et al, 1987


” [A] study showed a 7% increase in squat strength after 5 weeks of training with 3 minute rest periods.”- Kraemer


“…these quick-but-killer efforts may be the closest thing you’ll find to a magic calorie-burning bullet. You not only log less sweat time (which is kinder to your body) but also continue to incinerate calories at an increased rate even during the walking or jogging recovery periods.”- Westcott
