Question: how sore is too sore?
Answer: Exercising When You're Already Sore “My rule is that working out with a little bit of stiffness or soreness is okay. If it's a 1, 2 or 3 out of 10, that's okay. If it's getting above that, or the pain is getting worse during activity, or if you're limping or changing your gait, back off the intensity of the workout.”
