The Palms-Down Solo Sky Tricep Crusher

Pressure Cascade · Mechanism

Raise one dumbbell overhead with your palm facing forward, bend your elbow to lower the weight behind your head, and press it back up — that's the One-Arm Pronated Dumbbell Triceps Extension, a beginner tricep exercise that targets the long head with a pronated grip. The palm-facing-forward grip changes the emphasis slightly compared to the standard neutral-grip extension, hitting the triceps from a different angle that can stimulate new growth.

You hold a dumbbell in one hand with your arm extended overhead, palm facing forward — that's the pronated position, like you're giving the ceiling a very firm high-five. You bend your elbow and lower the dumbbell behind your head, keeping your upper arm vertical and your elbow pointing straight up the entire time. Your upper arm should not move — it stays pinned in place like a structural column, and only your forearm moves. You press the dumbbell back to full extension, squeezing your tricep at the top like you're trying to push the dumbbell through the ceiling. Then you repeat until your tricep files a formal complaint, at which point you switch arms and do it all over again.

The pronated grip shifts some of the emphasis to the medial head of the tricep, which doesn't get as much attention in standard extensions. It also challenges your forearm and wrist stability in a different way than a neutral grip, building overall arm resilience. This exercise is beginner-friendly but incredibly effective, especially for building the long head that creates the most visible part of your tricep when your arms are at your sides. Press overhead, lower behind the head, and crush those triceps into submission one palm-down rep at a time
