Hang weights from rubber bands on the ends of a barbell and lock it forcefully into your snatch overhead position. Keeping it as stable as possible, take the prescribed number of steps, stop and stabilize, and perform the prescribed number of overhead squats, then repeat for the prescribed number of times.
 
The goal is keeping the upper back, shoulders, arms and bar as motionless as possible with continuous active effort to stay tight.
 
Purpose
The snatch-grip overhead carry + overhead squat with hanging weights is a simple way to improve overhead stability for the snatch, as well as condition the hands and wrists in particular for overhead work. The hanging weights increase the demand on stabilization.
 
Programming
4-8 steps + 1-3 squats 2-4 times per set are generally appropriate for 2-5 sets. The majority of loading should be added to the bar conventionally, with the hanging weights relatively limited—10-15kg/side hanging is usually about the most necessary and even possible practically.
 
Variations
Chains can be used instead of bands and plates.
