Wow! Look at that. Some seriously nice work, dude. I think strength 1 would be a great choice as a next program. However…
And not to talk you out of not spending money with us, you just experienced a very impressive increase in strength. So much so, that it’d be irresponsible of me (as a coach) to ignore that response and advocate for a programming change. You could run the same program again and get great results (again). Might be worth a consideration if you found it enjoyable
