dude, hard work in the gym is always worth it man, dont stop.
look at your strength from 1 year ago, compared to right now. at all the lifts. how much did you squat last year? deadlift? power clean? how much could you row?
have you improved in terms of strength in 1 year?
look at your training logs from 1 year ago. if there isnt a great improvement, thats where you went wrong.
if there is no improvement in PERFORMANCE, there is no increase in MUSCLE.
if you want to be bigger, improve on the core liftss.
its very unlikely to deep squat 400+, deadlift 400+ and not be at least respectively built.
those are both very attainable goals that i am nearing myself.
remember the 3 pillars of fitness: the thoughts you think, the food you eat, and the exercise that you do.
dont underestimate the thoughts pillar. you gotta change up your mindset man, and go back in the gym ready to set some RECORDS. YEAHHH!
intelligent, hard work will solve a lot of your problems
