Row Tow Tone Your Arms
Rowing a boat can give you spectacular arms, but since most of us dont have access to water (or a row boat), simulate this exercise in the gym with an Olympic bar (the long bar you use to bench press). Stand with the bar between your legs and pick up only one end. Walk backwards until your about in the middle of the bar. In a slightly bent forward position, bend your arms to bring the bar closer to your body and then extend it in a rowing motion. Perform 20 rows. For even more arm toning, start in the same position and circle the bar 10 times clockwise and then 10 times counterclockwise as if you were stirring a big pot of soup from both an upright position and a bent over one.
