How many hours have you wasted listening to locker room know-it-alls describe their complicated workout routines: 20 reps of this, 20 second break; 30 reps of that; 30 second break….? Now comes research from Southampton Solent University suggesting that when it comes to exercise, simple is just as good as complicated. That’s right, it doesn’t matter if you start slow and work up to the greatest resistance; what matters is that you do it. The researchers also found that altering the intervals had no influence on the benefit of exercise. Really, the most exhausting part of exercising shouldn’t be listening to someone tell you how to do it. Read the study in Applied Physiology, Nutrition, and Metabolism.
