40 years old and lifting the past 5 years (2 of them seriously). Current stats are 6’2” 187 pounds roughly 16-18% bodyfat. I did a 3 month cut last year and went from 210 to 180. I have been on a very small caloric surplus the past 4 months and have added 7 pounds back onto my frame. My issue is that I am 6’2 with arms that are only a hair above 15”, chest is 43”, waist is 32-33”, quads 22” and calves at 14”. Certain angles I looks ok but all in all I still feel skinny. Current lifts are squat 260, dead 405 and bench 260. These are 1RM. I feel as if I should have progressed mich further in the time I have been lifting. I should add that I jave been on TRT for the past year and I am sure this contributed to my fat loss originally. Just looking for advice on a decent intermediate program. I am looking for size.
