Nothing wrong with 5/3/1. Most of the time it is the programmers fault not Jim’s. Since you are doing jokers how low did you set your TM? Are you eating like a motherfucker? When you are not looking forwards to the next meal or shake that’s when you are eating enough.
Are you doing too much bullshit after the bench or on other days? I would reset the bench TM by 85%, eliminate all other BS from the session and only concentrate on the bench. The Beyond programming IS your accessories and is built in.
Lastly the bench is and can be a bitch to get to climb. Sometimes it just takes a while as not everything is going to gain the same from cycle to cycle.
