A configurable exercise apparatus is disclosed for facilitating safe and effective hip extension exercises. The apparatus comprises a frame, an upper body support pivotally attached to a rear portion of the frame, a foot support forward of the upper body support, and a cross-member disposed between them. The cross-member limits knee movement and allows shin engagement, while the upper and foot supports are adjustable to optimize user alignment. Interchangeable foot surfaces and an elongated upper body support provide stability and ergonomic positioning during exercise. The system enables controlled hip articulation through a customizable range of motion.

The application discloses a six-degree-of-freedom light high-compatibility foot-ankle rehabilitation exoskeleton, which comprises an ankle-tibia connecting rod module, an ankle joint shaft module, a forefoot fixing module and a hindfoot fixing module; the ankle-tibia connecting rod module is used for being fixed in parallel with a lower leg and providing a power assisting anchor point at the back side of the lower leg; the forefoot fixing module and the hindfoot fixing module are respectively used for being fixed with the front end and the rear end of the foot of a wearer and providing an end power assisting anchor point at the heel; the ankle joint elastic element is directly contacted with the shoes of a user, and six-degree-of-freedom flexible interaction force is generated.
