I've read/heard that when doing box squats, you should take a wider then normal stance. I know that the box squat is suppose to be more of a p-chain movement so maybe a wide stance has something to do with that. However, I was wondering if I could use my normal stance for box squats.
Would the emphasis change? My stance is a little wider then shoulder width apart. I can sit back more with my legs wider, but I still feel like I need to sit back more with my normal stance instead of sitting down because when I squat, I can't seem to stay upright. I have more forward lean then people that I've seen on instructional vids I've seen.
Also, in the program I'm doing, I do back squats 4-5x1-6. Should I stick with this rep scheme or do 10x2? And what percent of my max squat should I use. I've read a person should use 50-60% but I feel like I'd just train for speed with that. I feel like I should use between 85-100% of my squat. I know I can't do 100% of my back squat, but I just mean I need to use heavier loads then 60%. Any thoughts?
