Why Athletes Swear by Foam Rollers—And Why You Should Too - AI Podcast

Story at-a-glance Foam rollers are cylindrical devices that apply pressure to muscles, helping relieve tightness and inflammation while improving flexibility and range of motion Research shows foam-rolling significantly boosts flexibility immediately after use, but provides minimal improvements in athletic performance like jumping, sprinting, or strength training Foam-rolling is theorized to work through three mechanisms — loosening fascia around muscles, improving blood circulation and temperature, and activating nerve receptors that reduce pain perception Studies demonstrate foam-rolling enhances pre-workout preparation by improving ankle mobility and single-leg balance, making it effective for warming up before exercise as well Four basic foam roller exercises target major muscle groups — hamstrings, back, calves, and quads, each performed for approximately 30 seconds per area
