BodyPump

BodyPump is a weight-based group-fitness program, created and distributed globally by Les Mills International. Every week 5.5 million people attend a Les Mills class in 17,500 licensed health clubs in over 100 countries.

In January 2017 BodyPump celebrated its 100th release(25 years) from centers all over the world

The first BodyPump classes were created by Phillip Mills and his wife Dr Jackie Mills in December 1991 in Auckland, New Zealand. According to Dr Jackie Mills the idea was to attract men into the group fitness studio while also breaking down the stigma that women shouldn’t, or couldn’t, do weight training.

BodyPump classes are 59 minutes long and contain eight separate muscle-group specific songs or "tracks" along with an opening warm up track and closing cool-down track. There are also 45-minute and 30-minute class formats.

The classes are performed to music using free weights-plates, barbells and an aerobic step. Participants choose their weights based on the exercise and their personal goals. Major muscle groups are worked via series of compound and isolation-based exercises including squats, presses, dead lifts. The focus is towards muscle endurance by moving light weights at high repetitions, what Les Mills calls the Rep Effect.

In 2011 Les Mills introduced the Smartbar, a barbell designed for BodyPump workouts.
