Abstract: A training apparatus provides a modular frame for performing group exercises. The frame includes a first, second, third vertical posts configured upright on a horizontal supporting surface and a crossbeam extending from a top of the second vertical post and a top of the third vertical post. The first vertical post and the second vertical post define a first vertical plane. The first vertical post and the third vertical post define a second vertical plane. The first vertical plane and the second vertical plane are arranged at a substantially right angle to each other. The crossbeam is adapted to be assembled with at least one first training attachment which is adjustable in a horizontal position. The second vertical post and the third vertical post are both adapted to be assembled with a second training attachment which is adjustable in a vertical position.
