Bulk is stalling
Been trying to bulk for like 7 months I guess now after finishing a pretty hard cut but my strength is not really going up. My lifts fluctuate alot and some days i can barely lift my usual. I do my best to find my maintenance everyday because my activity really does vary from day to day and ive been experimenting with around a 100-200 cal surplus but i dont think i am gaining weight. My plan was to go the lean bulk maingain route because i really do not want to do any sort of dirty bulk ever again but idk what to do. Is it because i am too lean and need a heavier surplus? I understand there is variation and its very hard to find your true maintenance but i am like 118lbs F 5”8 and ive got my maintenance at around 2100 (including my cardio and gym) which is pretty spot on i feel, and i figure out the met for any activity im adding onto the day. Any help what to do?
