I would never say bad workout. I love being in the gym. Only tough part is when the body is exhausted and it don't want to do what the mind says let's go! I love being there either way. To me it's like the saying about fishing. A bad day lifting is better then a great day working! LolTough days, weeks and workouts go hand in hand, better you had a bad workout got it in, then not doing one at all.
