Ive been doing toe add 30 in 30, on friday of my third week I was benching 85% or my 1rm and brought a friend to spot, figured while I had him there Id check my max. so i did my 2 sets of 2, added 20 lbs, did 1 rep, added 10 pounds, brought the bar down, started up and it started coming back down my upper chest hurt a little and I finished my workout. monday went back in and could barely push the bar on the left side and boy was it sore. I pushed out 2 sets then dropped some weight and did one more. its still pretty tender and it affects my workout. gonna give it a few days off. what do you think happened? should I not work it till it feels better?
