Deads. My squats are limited by shoulder injuries and are uncomfortable. I get by using a multitude of squat techniques to try and make up for it. Lately I've only been squating up to 225-275 depending on how I feel then switch to front box squats and work up to 275-315(again weight is dictated by shoulder condition that day). Leg day is frustrating but everyone has their shlt I suppose. I love doing deads and find them most gratifying. my shoulder injuries do limit me somewhat but I can still pull 405 which in the weightlifting world isn't a lot but in my world that's seen the inside of an ER more times in 8 years then most will see in two lifetimes , its very satisfying. I'm looking forward to pulling a 500lb dead one of these days. I just start doing deads from a deficit and incorporated some new posterior and lateral delt lifts to build up what ill need to advance without tearing my shoulders out again. Look twice for bikers god damnit!
