Is there such a thing as too much exercise?
Quite simply, yes.
Most folks don't have this problem, of course, but since I'm on class number 6 in just 48 hours, let's examine what happens to your body if you work out too much. There are a couple of really important words to discuss: catabolic, and anabolic.
Things that are catabolic (destructive metabolism) break down your body, and set it up for either injury or illness, or both. When we lift weights, for example, we are creating microscopic tears in the muscle tissue. Then we REST those muscles for 24 hours, and they get stronger from the stimulation. However, if you don't allow the rest portion, you keep breaking down tissue, and you end up breaking down your body, rather than building it up. So while I needed to keep my regular class load, and cover for some fellow instructors, 6 weight lifting based classes in that short a period of time isn't recommended. Even if you lift less than normal weight, you are still asking your body to do too much of the same thing.
Things that are anabolic build in a positive way--constructive metabolism. Mixing your types of workouts to include cardio, weight lifting, and plenty of restorative stretching are ways to build up your body in a positive way. Building muscle is still initially a destructive process--to stimulate we overload--but giving the muscles recovery is what separates the wheat from the chaff.
So be sure you are giving your body recovery through different types of exercise, and be sure to have 24 hours between lifting sessions. One way to be sure you are getting enough recovery is to alternate muscle groups throughout the week: Monday, legs Tuesday, chest and back Wednesday, arms and core Thursday, legs Friday, chest and back Saturday, arms and core Sunday, rest This is just one possibility among a myriad of ways to approach exercise is a healthy way for your body. But most importantly, listen to your body. If it's crying out, you are hurting it. Too much is as bad as too little. Find the balance that's right for you.
