Abstract: An apparatus for exercise use, which is easy to carry, fold up, and that can be used in methods, which include workout programs to help people improve athletic performance and promote weight loss. The apparatus may include first and second U-shaped members, and first and second attachment devices, which connect first and second ends of the first and second U-shaped members, such that first U-shaped member and the second U-shaped member form a substantially rectangular shape when the apparatus is placed in an unfolded and flat state on a ground surface, and the apparatus can be placed in a folded state in which the first U-shaped member sits on top of and is substantially aligned with the second U-shaped member. The apparatus may further include first and second straps, which form a plus sign, and which together with the U-shaped members may form four substantially rectangular openings.
