How do you isolate the lateral tricep?
How do you activate all 3 heads of triceps?
Using an underhand grip turns the move into a pulldown, which will work all three heads of the tricep. The overhand grip targets the long head of the tricep specifically. Your feet should be close together but not touching.
What tricep exercise hits all 3 heads?

Extend your arms to lift the barbell back to the starting position. Close-grip pushups, which require the same movement at the shoulders and elbows as close-grip bench presses, also work all three heads of the triceps.
