The main difference between Reverse Hyperextension and the original version is that during the training on the reverse version the the torso is the most loaded part, but not the legs. Consequently, the muscles of the buttocks and thighs work harder, and the muscles of the back only assist. In fact, the reverse hyperextension is working on the same muscles as the classical one, but changing the stress accent this option can be called safer.
The traditional way involves focusing on long back muscles and knee joints, which implies the chance of an injury while working with a big weight. The technique of reverse extensions, on the other hand, allows professional athletes to use extreme weights.
The Reverse Hyperextension is recommended to athletes of different levels of physical training for warming up muscles before performing more severe training, as well as for beginner athletes for warm-up before pulling exercises.
