TRX Bicep Curl

Hold the straps with your palms facing up and lean your body back at an angle, arms extended toward the anchor point above you. Keeping your body straight and rigid, curl your hands toward your forehead by bending your elbows, which pulls your chest up toward your hands. Your own bodyweight and the angle you're leaning at set the resistance — the more upright you stand, the easier the curl. Lower back to a full arm extension under control rather than letting your body drop toward the floor. Keep your elbows pointed forward and your core braced so the movement stays in your arms instead of turning into a sway from your hips.
