thnks…for the responses. I will keep this in mind:
Keep the weight on the heels.
Go down far enough.
One last thing…
I some people lean forward and others keep their torso vertical or close to it, wich one is the best form. (on a back squat)
unless you’re using a really light weight i don’t see how you are going to keep your torso vertical except at lockout
the important thing is to keep the weight balanced at the center or preferably near the heels
similarly leaning forward excessively will shift the weight to your toes and put lots of stress on your knees
doing back squats is the same as sitting down on a chair, as you try to sit down your hips will go back which will cause your torso to deviate from vertical, it’s more important to keep your back straight throughout the movement
