Boredom means you work hard. I wonder if there is a stretcher in your gym, which is specially used for stretching after exercise to prevent muscle soreness. If not, you can pull your arm and press leg press on the railing somewhere, so you won't be so weak. I have been exercising in the gym recently. I haven't lost much weight for almost two weeks, but I won't gain weight after eating it. Stick to it, you can't build your body in a day or two.
