Well I got back about 2 weeks ago from a trip to Germany for a month with my family. I started going back to the gym on Tuesday. I was stupid and kept on going with the weight I had been using before I left and didn’t work up to it at all.
Now mostly my left bicep, chest, and left shoulder are extremely sore, like my left bicep hurts to touch. Am I right that this is because of me being stupid and not working up to the weight? Also any ways to get rid of soreness would be greatly appreciated.
