Yes, this is super weird. But it nails the transverse abdominis (the deep core muscle that's like a natural weight belt) and even the internal obliques.
The transverse abdominis is a deep core muscle that acts as a natural weight belt for your spine. It's the Spanx of your abs. Developing it will help prevent injuries and create a smaller waist. You could train it with plank variations, but I like this exercise using an ab wheel and a treadmill.
Hold the ab wheel the same way you would for a rollout, but instead of rolling out, you hold it like a plank. This will also hit the internal obliques. It's fun and quite possibly a better use of the treadmill than jogging for abs. The slower the treadmill goes, the harder it is.
The goal of this article is to teach you basic triceps anatomy coupled with the knowledge necessary to design a triceps training program that'll increase your functional strength and power.
The Shotgun Method allows you to train for both size and symmetry without having to skimp on either. It actually allows you to concentrate on the big lifts without neglecting isolation exercises that address lagging body parts.
