The Rep Effect
The secret to BODYPUMP is The Rep Effect – a breakthrough in resistance training that helps create long, lean muscles and a toned, strong physique.
Research has confirmed that BODYPUMP™ has strong calorie and fat-burning effects and it improves aerobic fitness, muscular strength, and muscular endurance. There is also evidence that BODYPUMP classes can have positive psychological benefits.
The secret to BODYPUMP is The Rep Effect a breakthrough in resistance training that is proven to deliver a total body transformation. The Rep Effect throws traditional thinking about lifting heavy weights on its head. It exhausts muscles using light weights, while performing high repetitions.
Using The Rep Effect, BODYPUMP classes give you sculpted shoulders, defined biceps and triceps, strong lean legs, firm glutes and a tight core. Choreography in each of these areas is specifically targeted so you'll burn fat, burn more calories and achieve more meaningful fat loss and muscle fatigue. The end result is that you build strength without building bulk.
In a typical BODYPUMP class you’ll perform between 800 and 1000 reps in a single group workout. That’s more than four times the amount a person can achieve when training alone.
