I can't find much information on this variation, but sometimes when I am at the gym and most of the 45 plates are being used I will instead put 225 on the bar and stand those step up plastic pieces (for elevation) and do deadlifts like that. It just allows me to go deepers into the lift and I feel it more in my hamstrings after I go past where the ground would be. I just randomly thought of this one day and I can't find information on it. My grip on deadlifts is as if I was bench pressing. I only do mixed grip when I go up to 405. My grip can't keep it from rolling in the other formation.
Also, to the tall people. Is deadlift your strongest lift? I seem to explode in deadlifting, but all my other exercises are lacking. My squat max is only 225 for 6. and my bench has yet to break 200 pounds, but I can somehow deadlift 405 for 8 reps comfortably.
I've been training off an on since I was 17 in weightlifting class in school, but I never got serious until this last year or so. I only took weightlifting and advance strength and conditioning for the credits.
