If you're pushing yourself at the gym in order to reach certain fitness goals, you may actually be working against yourself. Dr. Brian Grawe, an orthopedic surgeon at the University of Cincinnati, says this situation is actually pretty common. "Some people can actually exercise too much," he said. "By over-training our bodies, eventually our athletic performance will plateau or even decline." These plateaus can effect your fitness levels or weight loss goals, and they happen when your body starts to burn out.
Tyler Spraul, a certified strength and conditioning specialist and head trainer at Exercise.com, agrees. "When you exercise too much, your body will eventually start to grow weaker and continually break down, instead of recovering and growing stronger as you would expect to happen when following a good training program," he said. "Basically, your body is going to find ways to make you take a break." Shorten your workouts, or maybe just take a break for a few days, to give your body a chance to rest.
Celebrity fitness trainer Autumn Calabrese adds that exercising too much can even cause you to lose the muscles you've already built, saying, "Over-exercise prevents your body from building muscle, leading to lean muscle loss."
