"Background: I am a woman, mid-thirties, been lifting for about four months. Height 5'9", weight 148 lb, squat 140~150 lb, bench 110 lb, press 70 lb, clean 85 lb, and deadlift 170 lb (all but the DL are working weights for sets across; I've had to dial back squat weight as I keep hitting a wall). Oh, I can do 5 sets of 5 chin-ups--pretty proud of that one!
The problem: I have worked my way up to squatting my body weight twice now and had to back off. The first time, I felt a pain in my lower back. Now, I am experiencing some intermittent pain in my knees and soreness in the front of my hips. I know that this *could* be due to my knees traveling forward at the bottom of the movement, as explained in the squat chapter of SS. But I just can't figure out a way to attain below-parallel depth while keeping the bar path vertical without my knees traveling forward somewhat. Thoughts?
Before re-reading the squat chapter, I thought that my hip tendons were hurting due to insufficient recovery, and I am taking a rest week right now to take care of that. I am eating a fair amount, 2400 kcal/day, with 150 g of protein a day. Lots of cultured dairy and whey protein powder as well as some milk--cannot stomach too much uncultured milk, unfortunately, due to a bit of lactose intolerance.
Another relevant bit of information: I have had lower back problems pretty much all my life, and I had arthroscopic surgery for a meniscus tear in my right knee 15 years ago. My knee gets a little sore now and then but doesn't generally bother me. I am flexible, which means I get injured easily."
