A spring-loaded adjustable workout handle apparatus for adjustable height and cushioned workouts includes a handle having a parallel portion and a pair of perpendicular return portions. A pair of support tubes is coupled to the perpendicular return portions. Each support tube is cylindrical and has a sidewall and an open bottom end. A pair of support legs is coupled to the pair of support tubes. Each support leg has a shaft portion and a foot portion. The shaft portion is slidably engaged within the open bottom end. Each of a pair of springs is coupled within one of the support tubes and is compressible by the shaft portion of the respective support leg. Each of a pair of adjustment mechanisms is selectively engageable with the pair of support tubes and the pair of support legs to adjust a fixed height of the handle.

An abdominal exercise apparatus can include a track, at least one rolling member, a cart, and a base. The track can extend between first and second ends. The rolling member can be moveable along the track. The cart can support the rolling member for the movement along the track and be grasped by the user during exercise. The base can be engaged proximate to the first end and have a surface configured to receive the knees of the user during exercise. The second end can be pivotally movable about the base over an arcuate range by the user while exercising during the rectilinear and rolling movement along the track by the at least one rolling member. The apparatus can also include a structure such as a helical spring for resisting pivotal movement that is elastically deformable.

Apparatus (60) for supporting a subject (2) in an inverted state comprises a ground engaging plinth (8) and a support platform (12) pivotally coupled to the plinth (8) about a first pivot axis (15) so that the support platform (12) is pivotal between a first state with a subject (2) in a supine state on the support platform (12) and a second state with the subject (2) inverted on the support platform (12). The subject is supported in the inverted state on the support platform (12) by shoulder engaging elements (24), and is secured to the support platform (12) by a torso strap (35). A foot engageable element (77) connected to a weight carrying bar (84) through connecting members (79,82) extending through an elongated slot (80) in the support platform (12) allows leg and abdominal muscles to be exercised by urging the foot engageable element (77) in the direction of the arrow A against weights (85) carried on the weight carrying bar (84). A carrier element (81) slideable on a guide bar (83) guides the foot engageable element (77). Handgrips (86) are connected by steel cables (87) around pulleys (88,89,90,91) to the weight carrying bar (84) for facilitating exercising of arm, shoulder, chest and back muscles.

A body held sparring device configured for either striking or being hit with the addition of a secondary target. The secondary target is offset from the sparring tool and designed to yield when struck, rather than transmit dangerous torque to the body part holding the sparring tool. Additionally, the sparring tool can further incorporate additional sparring tools, additional secondary targets and or additional control body points. A body held sparring device comprising: a U-shaped structure, at least a first sparring tool, and at least a first target wherein the first sparring tool is configured to be controlled independently of the U-shaped structure and to simulate punches being thrown by an opponent such as jabs and crosses. Wherein the first target is configured to yield when struck to reduce the amount of torque received by the body part through the structure.
