I'm so tired of the mundanity and repetition that even thinking feels like a chore now. Anything to escape this rut

Why didn't any of you fat fucks tell me about the part where your muscles start becoming huge from all the exercise that you're doing to lose weight so that it actually starts becoming easier to burn calories again. I maxed out the exercise bike and thought it was broken and then tried another one and it was the same and burned 1100 cal beteween the two, and then I thought the calorie counter on the bikes was broken and overcounting so I weighed myself this morning and lost 1.5 pounds. I didn't even feel that tired.
