I feel pretty confident doing the deads so far. I started by finding my max about a month ago which was 405. Then I started actually doing them as a regular part of my weekly split only two weeks ago. I started with 315 for 5x5. It feels really good to do them and in my gym it's rare and scares people. Anyway I was wondering if I should wear a belt or wrist straps. I did 325 for 5x5 last week and by the end I could feel that my grip was getting tired.
