Take the first 10 or so minutes of class to find a max height box jump. Stack plates (not boxes) to get your desired height.
“Cindy” should be treated any way you need – some may want to scale so that you can get 15+ rounds, while others just got their unassisted pull-ups and want to go Rx. Since it’s an AMRAP, this is a safe place to experiment and challenge yourself. Scaling options include reducing the rep scheme (3-6-9 or 4-8-12) or doing assisted pull-ups with a band or ring rows, and doing inclined push-ups.
