Instructions
Band Skull Crusher
Secure a band to the base of a rack or the bench. Lay on the bench so that the band is lined up with your head.
Take hold of the band, raising your elbows so that the upper arm is perpendicular to the floor. With the elbow flexed, the band should be above your head. This will be your starting position.
Extend through the elbow to straighten your arm, keeping your upper arm in place. Pause at the top of the motion, and return to the starting position.
JM Press
Start the exercise the same way you would a close grip bench press. You will lie on a flat bench while holding a barbell at arms length (fully extended) with the elbows in. However, instead of having the arms perpendicular to the torso, make sure the bar is set in a direct line above the upper chest. This will be your starting position.
Now beginning from a fully extended position lower the bar down as if performing a lying triceps extension. Inhale as you perform this movement. When you reach the half way point, let the bar roll back about one inch by moving the upper arms towards your legs until they are perpendicular to the torso. Tip: Keep the bend at the elbows constant as you bring the upper arms forward.
As you exhale, press the bar back up by using the triceps to perform a close grip bench press.
Now go back to the starting position and start over.
Repeat for the recommended amount of repetitions.
Verdict
Both exercises target the triceps. Band Skull Crusher is a beginner exercise using bands, while JM Press is beginner and uses barbell. Choose Band Skull Crusher if you have access to bands, or JM Press if you prefer barbell. JM Press is a compound movement working multiple joints, making it better for overall strength. Band Skull Crusher isolates the target muscle for focused development.
