In a country where the focus is increasingly on those that are too sedentary, it is hard to believe that there is also an increasing focus on those who are too active.
Recent reports on MSNBC are saying that our bodies don’t bounce back as well after more than 12 hours of exercise a week. The reason for this is that over- exercising can cause injuries (such as muscle strain) to adults but it can also cause oxidative stress, in which oxygen molecules (called free radicals) are formed. These free radicals can damage DNA and cells in ways that, over time, can accumulate to cause cancer.
A good rule of thumb is to be more in tune with your body and if you are tired or achy, take a rest. Also, take days off and vary the intensity of your workout.
Fit's Tip: I know it's easy to take this as an excuse not to work out (since I rarely give you one) but that is not the point and whatever you do, don’t stop exercising.
