Just wanted to get one in today. Back is still pretty sore. I chose the front squats because they have not hurt my back in the past. About 15 min after my back started to hurt. I am posting this 9 hours later and my back is killing me. I guess I am hurt worse than I thought. I hope with all the traveling I don't make this worse. I am going to have to stay away from anything that puts pressure on my back for the next few weeks.
