Foam rollers can benefit weightlifters in injury prevention by helping to increase blood flow and release muscle tightness, which can improve flexibility and decrease the risk of muscle strains. Regular use of foam rolling as part of a warm-up or cool-down routine can aid in the recovery process by facilitating the removal of lactic acid and reducing soreness. This practice can also help in maintaining a greater range of motion, which is crucial for performing lifts with proper form and preventing injuries.
