So I started the Christophers routine today after months and months of just doing dumb shit like shrugs and various curls and bench press. However, I find myself to really suck (which I expected). Bench I can do, no problem. Squats, I think I got, but I'm wondering if I should be doing Olympic squats or just regular ones. How far should I drop down when squatting? Should my hamstrings be parallel with the floor? Is it better to do squat a higher weight without dropping down so much, or to squat a lower weight and dip down to like ass behind knees? And then we come to deadlifts. I'm pretty sure I understand the form, I even tried using straight leg deadlifts and having a guy at the gym help me out, but I'm having a lot of trouble keeping my back straight when deadlifting. It happens right as I try to get the bar over my knees. Part of me feels like it is a result of my height (6'5"), but can someone advise me how I can practice deadlifts without arching my back, or just give some tips? Any help would be loved.
