similar to cali press, try this the next time through.
a combination of three movements: skulls, a roll, and close grip. Lying down, extend your lower arms with your elbows as your pivot point (just like a skullcrusher) but bringing it down to your throat instead (controlled!!!). from there, roll the bar right along your front past your chest and to the upper abdomenal. after a slight pause, close grip that son of a batch and there's one rep for ya. Lot of lifters have little to no problem with the lateral and medial heads of the tris. The long head a bit more challenging, especially running down towars the elbow. This exercise ive found, really hits all three heads of the tricep.
