CHIN-UPS

Chin-ups strengthen back muscles, biceps and shoulders. A simple repositioning of the hands works other muscle groups.

You can buy an inexpensive chin-up bar at any fitness retailer; be sure it's installed properly or you may find yourself doing chin-ups in a hospital bed. {relatedarticles}

If you're truly looking to go old school, find a low-hanging beam, hold on tight and go to work.

Stop paying gym fees; stop being gawked at by middle-aged men in biker shorts, stop buying gimmicky exercise machines from washed-up actors, and stop wasting time and gas driving to the gym. Have fun. Get fit. Go old school.
