Which flexibility training method involves the use of a partner?

The flexibility training method that involves the use of a partner is proprioceptive neuromuscular facilitation (PNF). This technique often requires a partner to assist in achieving a greater range of motion. In PNF, one individual performs a static stretch and then the partner provides resistance against that stretch, followed by relaxation, allowing for a further extension of the muscle. This method combines both passive stretching and isometric contractions, increasing flexibility effectively.

Static stretching typically involves stretching a muscle to its farthest point and holding it there without the aid of a partner. Ballistic stretching utilizes bouncing movements to push muscles beyond their normal range of motion, usually without the action of a partner. Active stretching relies on the individual contracting opposing muscle groups to stretch the target muscle without assistance. Therefore, proprioceptive neuromuscular facilitation stands out as the method specifically designed to utilize a partner for enhanced flexibility training.
