Apparatuses, Systems, and Methods for Improvement of Physical Fitness

An apparatus comprising:

• a strap having a first end, a second end, a length between the first end and the second end, the strap having an elastic portion between and spaced apart from the first end and the second end;
• a first handle configured to be coupled to the strap on a first side of the elastic portion such that the first handle is spaced apart from the elastic portion;
• a second handle configured to be coupled to the strap on a second side of the elastic portion such that the second handle is spaced apart from the elastic portion;
• and
• a first suspension member configured to be coupled to a supporting structure and to the strap at a first point between the elastic portion and the first handle;
• and
• a second suspension member configured to be coupled to a supporting structure and to the strap at a second point between the elastic portion and the second handle;
• where each suspension member comprises:
• a first flexible member configured to be adjustably coupled to the strap;
• a first bracket having a width, a height, and a thickness that is smaller than each of the width and the height, the first bracket coupled to the first strap;
• and
• a second bracket including a slot having a width and a height, the width of the slot being less than the width of the first bracket and being larger than the height of the first bracket, the height of the slot being larger than the thickness of the first bracket and being smaller than the height of the first bracket;
• and
• a second flexible member coupled to the second bracket and defining a loop through which the second bracket will fit.
