What I mean by this is that every time you go the gym, you use the same exercise, reps, and sets over and over. This can definitely cause your workout to suck because both your mind and muscles are literally bored. Stop being lazy and challenge yourself with some new and dynamic workouts every week, which will assure that every session is a new adventure. This will keep you on your game both mentally and physically so that going through the motions is a thing of the past!.
