Cobra Pulse: Step 1
This snake-like exercise trims your arms and builds muscle!
Lie facedown, holding your face slightly above the ground, with your abdominals tight. Bend your arms by your side, so your palms are in line with your ears and your fingers are spread.
Inhale and firmly press your palms and forearms into the floor as you lift your chest and roll your shoulders back. Keep your glutes tight and the tops of your feet on the floor.
