Power tower (exercise)

Power tower (exercise)

A Power tower, also known as a knee raise machine or knee raise station, and sometimes referred to as a captain's chair, is a piece of exercise equipment. The equipment most commonly has a backrest and fore-arm rests that form the chair, with vertical handles at the ends of the arm rests. This main piece is used for knee raises and the captain's chair exercise. There are often parallel horizontal handles as well for performing dips. Often, a pull-up bar is attached to the top.

Captain's chair exercise

The roman chair exercise, that works the lower back, is a complementary exercise to the captain's chair exercise that works the lower abdominals. The abdominal exercise using the captain's chair is performed as follows: Stand in the "chair", place the forearms on the rests and grab the handles. Supporting the body on the arms, lift the knees towards the chest, keeping the upper body straight, without using momentum. The desired action is similar to a crunch. Fact|date=September 2007
