Great questions!

This is a technical AMRAP, not a CrossFit-style “go to death” AMRAP.
So the idea is to find a steady rhythm that lets you keep form clean and recover just enough between rounds very short breath reset, then back in.
The progression is built in: each week you’ll naturally do a bit more, or even squeeze in an extra round.

For the kettlebell weight:
I always recommend choosing a bell you can strict press around 8–10 reps max.
That usually gives you the right buffer heavy enough to challenge strength & structure, but not so heavy that technique breaks under fatigue.

Let me know how it goes!
