Thanks man! Hip tightness was a huge issue for me when I was runnin SS in March-May this year. It got so bad I had a hard time walking without a limp. I was miserable and my squat hit a wall at 290. I knew I had the legs for it but the hip pain was stopping me. It pissed me off because I really wanted the 3 wheels.
I figure I just couldnt handle back squats so often and started focusing on front squats once or twice per week. My hips started feeling better, most likely due to the lower weight and less hip involvement.
Then I found
Joe Defranco's Limber 11 and read Matt Perryman's - Squat Everyday. Total eye opener dude.
I started doing the limber11 daily b4 squatting and the squats went up. Hips felt great and still do.
I found that my legs could recover from daily (4-6x per week) squatting but everything else suffered. my upperbody felt beat up every day while my legs felt fine. That was probably because I was trying to train my other lifts at the same time.
Squats every day = fine to awesome
Squats every day + other lifts = not so good.
Right now I'm running the LRB intermediate program from Strength, Life, Legacy - by Paul Carter
I'm not a fan of linear progression. I'm a big fan of double progression Hepburn style workouts.
Training more often is what lets you train more often.
