E-Z Bar or Barbell
1) Lie on a flat bench and hold a weighted E-Z bar above your head. Your head needs to be slightly off the end of the bench. Place your hands at shoulder width.
Keep your elbows slightly bent.
2) Inhale and slowly lower the bar towards your head. You want the bar to go past the top of your head - aim for about midway of your head. The bar itself should be close to your head as it is passing.
Make sure that you are only using your elbow joints to lower the weight and that you are not using your shoulders to move the bar back and forth.
3) Exhale and push the weight back to your starting position by only using your triceps (i.e. only moving the elbow joint).
