Feel. These are intended as fast, hard intervals that are still sustainable for the 3 minutes and can be repeated with only 2 minutes rest. This means finding a pace you can (barely) maintain through the interval (and recover and repeat your effort on the next one).
Begin with a hard row buy-in to each in AMRAP that allows you to transition quickly and get straight to work. Aim to keep the wall balls unbroken in the remaining time on A1, and a fast, hard pace on the burpees in A2
