i just moved back to college two days ago and i started working out yesturday... doing my usual back/shoulder day.. only problem i noticed is that i took too long, i tried to rest too much i don't know if i was over training or something.. the workout took me about an hour and 45mins which i dont like at all, i don't have that much time to do when calsses start rolling.. but then there is one thing i did do, i tried to do was switch around my routine, and also i added a little thing to my routine when doing the back, so maybe thats why i needed the extra rest but is there anything to worry about ?
