Many years ago, when I first performed the Barbell Squat, I began on the Smith machine. With a pad.
After a month of carefully increasing my load from 95lbs to 225lbs on the Smith machine, I decided to attempt the Barbell Squat in the cage!
After careful and gradual improvements in my Barbell Squat,
I removed the pad.
It felt really really weird without the pad, and my neck hurt. So, as a complete beginner, I used the proper safety precautions! Don't knock safety, bros.
