When I first started strength training at my gym, I felt sore for a couple of days following my workouts. Now, a few weeks later, I don't feel sore the next day but I do work my muscles to fatigue. Do you need to feel sore the next day to get the benefit of weight training? --T.E.

Soreness comes from throwing something at your body that it isn't used to. So even if you're in great shape and you try something new, you're going to feel soreness. Once your body becomes familiar with the activity, it has the defenses to prevent soreness. This is a good thing. Otherwise you'd be sore all the time.

So even though you're no longer feeling sore after your workouts, you're still getting a good workout. If you feel like you're working hard during your lifting session and pushing yourself to the point of fatigue, you're getting all of the benefits, and probably all of the results, you're after. Whenever you change your routine, there is a decent chance you'll experience a bit of residual soreness.
