On your own:
40 Box jumps (10 reps, 3 breaths x 4)
30 Box jumps (15 reps, 3 breaths x 2)
20 Box jumps (20 straight)
With a partner:
Intersperse sets of jumps with sets of partner work.
Travel in order (top to bottom) down both lists.
Rest is earned by hustling to and through the box jumps en route to the next partner set.
