Even if you exercise regularly, you've felt it: the aching, can't-sit-down-or-lift-my-arm muscle soreness the next day after a workout. That soreness you feel a day or two after an intense workout is known as DOMS, or delayed onset muscle soreness, and is caused by muscle microtearing, which helps build muscle fiber and make them stronger. I'm always a little pleased to feel sore after a workout, but even so, like many I've been guilty of using it as an excuse to skip out on a workout.
Last week, I was introduced to a few little-used muscles during a leg-focused strength-training session with my trainer at Crunch. Those subsequent days of dreading any stairs that popped up in my path led me to ask him how he deals with muscle soreness, and whether he recommends his clients power through the pain. Trainer Tim's response? Muscle soreness is rarely a good excuse to bypass the gym. Read on for his recommendations for dealing with muscle soreness during your exercise regimen.
