k, last friday was the first day i had worked out in about 3 months, i did my usuall Shoulder/back with a few sets of shoulder press, shoulder fly's, and shrugs and it was an ok workout for first day back i was doing each set to my limit, but now on sunday i'm still very very sore, and it's hard to do anything because my upper arms and shoulders are sooo sore even 3 days later, is this normal? when i worked out before i had never felt so sore, is there anything i can do ?? should i do another workout??
