As intimidating as this exercise sounds, it’s actually an excellent way to target your triceps and upper back muscles. You can perform this on a bench or on the floor using a single weight held horizontally between your hands, or two weights, one in each hand.

• Lay flat on your back with bent knees hip-width apart and feet flat on the ground.
• Press the weight up until your arms are fully extended.
• Bending only at the elbows, lower the weight to the side of the face and extend arms back straight to full extension, pressing the shoulders and upper back into the bench or floor.
• Keep core engaged at all times.
