About Jumping Jacks

The risks and benefits of combining stretching with warming up are disputed, although it is generally believed that warming up prepares the athlete both mentally and physically.

Jumping Jacks

A jumping jack (Canada & US) or star jump (UK and other Commonwealth nations), also called side-straddle hop in the US military, is a physical jumping exercise performed by jumping to a position with the legs spread wide and the hands touching overhead, sometimes in a clap, and then returning to a position with the feet together and the arms at the sides. The jumping jack name comes from the traditional toy of the same name, while "star jump" refers to the person's appearance with legs and arms spread.

More intensive versions of this jump include bending down (over) and touching the floor in between each jump.

A similar jump exercise is called half-jacks, which were created to prevent rotator cuff injuries, which have been linked to the repetitive movements of the exercise. They are just like regular jumping jacks, but the arms go halfway above the head instead of all the way above the head. The arms also hit the sides to help tighten the jump.

Beginners class usually start with a repetition of 10 times jumping jacks. Later on the repetition increases as you gradually progress through training.
