Mixed
Utilizing the hook grip (HG) during power cleans significantly increases one-repetition maximum (1RM), peak barbell velocity, and relative peak power compared to a standard closed grip (CG) in well-trained athletes.
If you perform power cleans or similar Olympic lifts, switch to the hook grip. It allows you to lift heavier loads and move the bar faster by securing the bar without excessive hand tension. Expect some thumb discomfort when you first start; give it a few weeks to adapt, and you will likely see improvements in your max lifts and power output.
GoodSupportsHIGH confidence
The HG condition resulted in greater PC 1RM (6.6%, ES=0.43), peak barbell velocity (2.9-5.2%, ES=0.41-0.70) and relative peak barbell power (5.7-15.1%, ES=0.32-0.71) at all submaximal loads compared to CG.
Why this rating
Randomized crossover design with well-trained subjects, though small sample size (n=11).
