Stretching is an important lifestyle choice that will pay healthy dividends for years to come. Stretch Buddy™ makes the choice easy. The Stretch Buddy is designed to be the ultimate tool to assist with self-stretching the whole body. The Stretch Buddy uses multiple foot and hand pockets throughout the strap to allow for greater gains in flexibility by performing PNF (Proprioceptive Neuromuscular Facilitation) self-stretching. This form of stretching is an active stretch that uses isometric contractions to help the body achieve greater gains in flexibility.
