According to a study published in the Journal of Human Kinetics, warming up is definitely beneficial. Researchers split a group of 36 athletes into three groups: those who did a 20-minute bicycling warmup before performing weighted lunges, those who only did a cool-down, and those who did neither. Everyone was given a pain threshold test on the two days following to determine muscle soreness, and guess what? The group who warmed up had the highest pain threshold and reported relatively ache-free muscles.
