3c L-Sit Pullup
Hang from a pullup bar with hands outside shoulder width and palms facing away from you. Bend your hips 90 degrees so that your legs are straight out in front of you (your body will form an "L" shape). Pull yourself up until your collarbone touches the bar. Perform reps for 30 seconds, and then rest 60 seconds. Repeat the circuit twice more (three total sets for each exercise).
