strong lifts taught me a ton too, you're progress is really pretty badass you went from average to pretty strong .. you don't see many guys benching 225 or deadlifting/squating 300lbs, feels good!
I've been doing heavy volume, major muscles 2-3x a week starting a few days ago, so far so good.
Here's what I do if anyone wants to critique:
Monday – chest w/squat (high rep)
Tuesday – shoulders w/ rackpull
Wednesday – Arms with closegrip bench for tris
Thursday – OFF
Friday – Legs with Benchpress
Saturday – Back with deadlift, curls maybe.
Sunday-OFF
Specific exercises:
I'm basically hitting deadlifts/squats 2x weekly, bench 3x weekly. Kinda seems like I'm doing high volume but my body responds pretty good to being abused, and I eat a ton of food so I think I'll be good. So far bench is increasing too and I feel swole 7 days a week.
