It was a long hiatus. I didn't go to the weight room since HS football. Now I'm hitting it hard again. I wore my arms out. I still lifted arms when they straight up HURT. But I didn't do much. I still ran everyday (4 miles a day or so), and lifted legs every couple days...
But I just don't understand how my arms/chest feel fine, but when I get the weight up, I can't do more than 5 reps of 135 when I was doing sets of 7 with 155 two weeks ago....
