What is the best way to work on balance for squatting? I was reading "Starting Strength" and Rippetoe says that when starting you need to squat down and push your knees out...my problem is that I can't get close to that point because I start to fall. I can only do a partial squat (with the bar or without) until I start to fall over. I put my weight on my heels and I'm doing the correct form, I just start to fall over when I get too low. Any tips on how to correct this?
