Ok so for sometime ive been debating with myself if deadlifts are better suited with back work or leg work. So what are the MAIN muscle involved with this lift? i know a lot of guys do deads for back thickness. But for me, my hams, quads, traps, and low back feel this lift the most. My actual lats dont become sore from this at all. Id like some science on what extra lifts would go with deads the best.
