Kneel down with physioball in front of you. While kneeling, allow your upper body to rest on top of the ball. Your chest and underarms should be firmly on the ball. This exercise can be done from a kneeling position or with the legs fully extended behind you.

Grasp any form of weighted resistance. Both palms should be facing up. While keeping your elbows firmly planted on the physioball, contract the biceps muscles by pulling the weights upward toward your shoulders. Slowly lower the arms back to the starting position. Repeat the motion for any desired amount of repetitions.
