Elitefts.com Inc. Advisor and The Spot Athletics owner JL Holdsworth performs a One Arm Deadlift with 315lbs with No Straps. Not only are One Arm Deadlifts an excellent way to develop and display grip strength, it is also an outstanding way to develop posterior chain strength. Lifters and athletes with upper extremity injuries have no excuse not only to maintain, but to improve their strength with this exercise. Forgot to mention that JL is right handed. That's 315 with his non-dominant arm!
