Muscle energy technique or simply MET, is a method by which the musculoskeletal function or joint function is improved. This manual therapy works on the principle of reciprocal inhibition, providing relaxation to the muscles on one side of the joint and to accommodate contraction on the other.

Muscular energy technique is practiced not only by manual therapists, osteopaths, and massage physicians but also by athletic trainers. These techniques are highly beneficial for people suffering from a decreased range of motion and pain.

Post-Isometric Relaxation and Reciprocal inhibition are parts of MET. In the former case, the therapist lengthens and stretches the muscle while the latter works on the contraction of the reciprocal message by contraction of the first.

This technique is highly beneficial for strengthening postural muscles, easing muscles by treating cramps, reforming and regaining muscle function and many more, it can be applied to almost every joint in a human body.
This technique is to prevent one from future injuries and wounds, most athletes use muscular energy technique as a safeguard.
