Step 1
Get a weight bench and adjust it so that it is flat. When you are on it you should be parallel to the ground.
-
Step 2
Get a preacher curl bar and add some light weight plates. Remember, you are working your triceps not your chest. You only need a little bit of weight for this small muscle group.
-
Step 3
Grasp the preacher curl bar with an overhand grip. Your hands should be on the part of the preacher curl bar that angles inward and upward. Your thumb knuckles should be pointed toward each other.
-
Step 4
Bring the preacher curl bar to your chest as you lay flat on the bench. Your feet should be to the sides of the bench flat on the ground.
-
Step 5
Raise the preacher curl bar straight up so that your arms are perpendicular to the ground. This is your starting position.
-
Step 6
Bend your elbows and lower the preacher curl bar toward your head. Stop just before you hit your forehead, then raise the weight to your starting position. This is 1 rep. Do 10 to 12 reps, then rest. Do 3 to 5 sets of skull crushers.
