First off ik yall, this is mgtow and its not a workout sub but ik a lot of yall on here workout, i couldnt find any other sub i could post this but anyways i could use some brotherly advice

Here's my my workout routine: 1 day upper a day or two later lower then rest and repeat, I workout abs both times, for upper body I start w 3 sets of dumbell press w 8 reps each using same amount of weight each time (35 lbs each hand), then do tricep and bicep machines then hammer curls all 8-12 reps, then lat pull down, tricep extension and end it off w chest press machine all 3 sets of 8. For legs i do about the same thing 3 sets of 8 for each leg machine, also i run 3/4 mile before every workout for each. Tbh I havent seen much progress in myself the past months and ive been gaining some belly fat while my chest stays the same, although my biceps have gotten bigger, but am i doing something wrong?
