Sydney, I thought it did I should update itWhich city are you in? Doesnt say in your profile.
Since you can't do squats at the moment I think leg press is a fine substitute if you can do them.
I'm also not the biggest fan off 531. The extremely slow progression is very boring and too slow for beginners. Also it just didn't work well for me when I did it.
How was the increase in strength? Should this be used later on when gains aren't as easy to get compared to starting out?
