Open Grip for Early Arm Push in the Jerk
If you push too early with your arms in the jerk and ruin everything, try this in your warm-up sets:
Open your hands completely in the rack position—feel the bar settled completely and securely connected your trunk.
You can also do the same from behind the neck, which usually feels stronger and more stable, meaning it’s even easier to trust your legs to do the work.
You should be able to jerk with a full grip on the bar in the rack (for those of you with the mobility and proportions for it) while still keeping your grip relaxed. However, you’ll tend to grip the bar too tightly even if you know you shouldn’t when you’re not confident.
Too tight of a grip will also prevent a fully secure rack position, which will then feedback and make you grip even more tightly and push even sooner.
Completely opening the hand prevents that unintentional gripping and lets you focus on balance, stability, rack security and complete, power leg drive.
Even once the bar is off your shoulders, only grip the bar tightly enough to control with the proper hand/wrist position overhead.
