2A L-Sit Dip
Stand between two parallel bars and grab each with an overhand grip. Straighten your arms so that you're suspended over the bars. Bend your hips 90 degrees so that your legs are straight in front of you. Now bend your elbows and lower your body until your upper arms are parallel to the floor. Perform reps for 20 seconds straight, and then rest 10 seconds. Then go on to the side lunge.
