Set-up: Set up with your hands touching each other and your upper arms close to the torso. With the toes together and hips up, establish proper upper body posture with a neutral back and braced core. A straight line should exist between your ankles, hips and shoulders.
Movement: Pull yourself into position by contracting your shoulder blades, then focus on your triceps and chest, maintaining strong tension and posture for the duration of the set.
Emphasis: Don't allow the hips or the lower back to sag. Don't allow the elbows to flare wide out to the sides.
