You will want to learn and progress this exercise in progressive “stages.” That’s the most effective way to learn.
STAGE 1: Master the movement without load, and while using a handrail or support for balance. This allows you to pattern the movement well without struggling.
STAGE 2: Once you feel comfortable with it and are moving correctly, you begin to load it – first with 10-20lbs – and then up to 35 to 45 lbs if you’re a male – 25 to 35 lbs if you’re a female.
STAGE 3: Train the movement without any support, relying on your own balance and hip stability to be able to power through, using as much load as you can handle, with control.
