Watch these videos. Ignore the weights or kettlebells. We will be doing AIR GETUPS. Do the exact movement, keeping an empty hand and straight arm perpendicular to the floor throughout the exercise. Please watch the complete videos so you are using proper form!! Strict form matters!
The below video breaks down the TGU into segments to help get the form down. The AIR GETUPS (and the TGUs) are meant to be one fluid motion. This video is for instruction, not as a demonstration.
