So I just recently got back into the gym after taking 9 months off. I was up to maxing out at 300 bench went to the gym again and had trouble with repping 185 5 times. I did a 5x5 routine when I first started and couldnt finish at 155. I just went today and finished it all up at 165 pretty damn easily. Is that muscle memory? Oh and I had trouble with 115 military press when I first came back. I was able to do 145 without any problem. Now I was doing 125 without much trouble. My biceps still seem to be not going along so well.
