Why: Skullcrushers are a great exercise to superset with other tricep exercises and work well as the second exercise because you can go fairly heavy with weight.
How: Lie down on bench and bring weight up. Keep arms straight up to ensure you’re working against gravity. Only bend your elbows. Avoid allowing upper arms to move. If they do, allow some of the load to your shoulders. Lower the weight under control, using a speed that is deliberate and consistent. Keep wrists straight and strong. Power weight back up but stop short of full extension to allow constant tension on muscle and no rest at the top of movement.
Nail it: Keep your elbows in tight and avoid elbow flare to ensure triceps do the bulk of the work. Allowing your elbows to flare reduces the triceps workload.
