Draw cards from a standard 52-card deck plus 2 Jokers. Each card drawn determines which exercise to do and the number of reps.
Suit determines the exercise:

Hearts = HSPU or HS-Kick
Diamonds = TTB or Dragon Fly
Clubs = WB shots 10/9ft 20/14# or Water Jug Thruster with a pair of 1 Gallon Water jug
Spades = Burpee
Card value determines the number of reps (face cards = 10, Aces = 11).
Jokers = 14 TGU 50/35 or 1 Gallon Water Jug (7 on each L/R)

Before the clock starts pick the first card from the deck to determine what exercise to do and how many reps. Card value = number of reps (face cards = 11, Aces = 13).
