10 box jumps
15’ handstand walk or 3 wall walks
30 double-unders or 90 single skips
then… how quickly can you complete a game of Solitaire Concentration? In Solitaire Concentration, a deck of cards is laid out face down. The player chooses 2 cards and turns them face up. If they are of the same rank (e.g. 6 of hearts and 6 of diamonds, queen of clubs and queen of spades, or both jokers, if used) then those cards are collected and set aside. If they are not of the same rank and color, they are turned face down again. The game ends when the last pair has been picked up. Time yourself, race someone with a 2nd deck of cards!
