"Don't go crazy." What does that exactly mean?

I love ambiguous phrases like "don't overdo it" or "don't go crazy."  What do they mean?  My idea of not overdoing it might be someone else's idea of totally overdoing it!  Do you see where I'm going?

Today was the second time that my physical therapist, Bryan, has used the phrase "don't go crazy" with me.  That cracks me up because he obviously knows me!  Today, I could not help myself; I had to ask him to define what that meant.  You know that phrase, "Go big or go home"?  Well, I get that!  What's the point of doing something (heck, doing anything) if you're not going to go big!  Well, Bryan's "don't go crazy" is pretty much the exact opposite of "go big or go home," so it was probably a good thing I asked for a definition!

A quick recap for all you kiddos out there: physical therapy is going well, and I'm up to 95% of my weight on the AlterG.  I'll do one more session on Wednesday at 95%, and then, if all goes well and I feel good, I'm set free & can start running outside again!  Woo hoo!  But here's where the "don't go crazy" comes in!  My PT's definition of "don't go crazy" means no more than 4 days of running each week (totally do-able), starting off with a run combo of something around 2 short runs of about 3 miles each, 1 medium run of about 4 miles, and 1 long run around 6-7 miles (again, totally do-able), and not increasing overall mileage by more than 5-10% each week.  Did you notice that I didn't say "totally do-able" there?  I'm mathy.  I get numbers, and I'm pretty good at calculating 5% and 10% of any number out there.  It's just that 10% is so small, and 5% is so much smaller!  With a 3-3-4-6 type of week, 5% more would add just 0.8 miles.  Since I like round numbers, I'd bump that up to a 1.  (Come on, you know you would too!)

But here's the thing: you don't need to worry about me.  Yes, I will take it slowly, and yes, I'll be extra careful!  I've got 11 teammates for Ragnar who need me in just about another 10 weeks.  If you think I'd risk letting them down, you've got another thing comin'!
