TRX Supine Pull Up
How To: Lie on the floor and grip ropes with your hands facing inward. As you pull youself up, keep your elbows tucked in to your sides. Do not lower yourself all the way to the floor, this way you will use your muscles throughout the entire movement. For beginners, bend at the knees. For advanced, keep legs straight.
Muscles Used: Trapezius Latissimus Dorsi Biceps
