I haven't lifted weights in probably 15 years, so you'll need to modify that number to something that makes sense.

In Climbing, I know that when I'm on form I can generally get a route graded 7b+ after a couple hours of working it and a few redpoint attempts. The few 7c routes I've done each took about a dozen days of work spread out over the course of a month.

The route I did on one of my pre-cold days was rated 8a+ (though it was likely a bit overgraded), and I got it second go. Like I said, I came back a week later, and I couldn't even do the single hardest move in isolation.

So, that far out of the ordinary.
