The purpose of foam rolling as part of a fitness routine is to aid in muscle recovery and enhance flexibility. Foam rolling helps relieve muscle tightness and soreness by using self-myofascial release techniques to target trigger points in the muscles and fascia. This process promotes increased blood flow, which can enhance circulation and nutrient delivery to the muscles, facilitating recovery. Regular foam rolling can also lead to improved range of motion and overall functional performance, making it a valuable addition to both warm-up and cool-down phases of workouts.
