Sit on the floor, with your leg together and extended straight out in front. Position the Pbars underneath your shoulders.
Grip the bars and lock your arms. Squeeze the triceps and rotating your shoulders into their sockets so your elbow creases face forwards.
Drive your hands downward, and depress and protract your scapula.
Compress your core, and lift your hips off the floor. Exhale as you press yourself up, squeeze at the top and relax down.
Repeat for repetitions.
Ensure you keep the arms straight.
