The Telle Curl

Here's the secret for bigger muscles: Challenge them in a new way. This exercise is a variation of the barbell biceps curl. "You alter your body angle to increase stress on your arms throughout the motion," says Bill Hartman, C.S.C.S., co-owner of Indianapolis Fitness and Sports Training.
The benefit
You're always stronger at the top of a curl than at the bottom, so this exercise shifts your body to increase tension at your weak point. By building on this soft spot, Hartman says, you'll potentially work your arms more and build bigger biceps.
How to do it
Hold a barbell with an underhand grip, your hands shoulder-width apart, and let the barbell rest against your thighs.
Keeping your elbows close to your body, curl the bar up to shoulder level. Pause briefly and contract your arm muscles.
Without changing the angle of your elbows, bend forward at the hips until your forearms are parallel to the ground.
Keeping your forearms parallel to the ground, slowly straighten your body to a standing position. Your arms should remain at about the halfway point of the curling motion. Lower the weight and repeat. Perform three sets of eight to 10 repetitions each.
