Outstanding deadlift Chris, particularly with NO lifting belt, multi-ply deadlift suit, or straps!!
Are you an all-natural weight-trainer? I see that you weigh approx. 225 lbs.
As we discussed in a previous thread, if you are drug-free then you can theoretically add roughly a third to this poundage (to adjust for doping) and to compensate for the lack of either a multi-ply deadlift suit/belt add another 50-100 lbs...so that would be what...approx. 850-900 lbs. "adjusted"?!
Back in my "prime", I eventually reached 605 lbs. at a bwt. of 200 lbs. with only a 4-in. wide lifting belt and no straps (used a hook grip). Sadly though, it was a "gym lift" and I didn't have a camera (how I wish!)...so I "honestly" can only claim my official PL contest lift of 520 lbs. at a bwt. of 185 lbs. (light in bwt. while competing in the 198 lb. class). Of course, these lifts were drug-free.
By the way, I watched Bob Peoples deadlift and he kept his hips high in the get-set position over the bar...almost like a stiff-legged dead with a "soft" knee lock.
Again, congratulations Chris on an outstanding dead, particularly w/o any belt/support-gear!!
By the way, have you tried to do a 1RM on the Gerard trap bar?
