Now take the deck of cards including the jokers. Give it a good shuffle and turn over the top card. Whatever the value of this card is the number of reps for the exercise.
Face card values:
With each card you turn over, do that amount of reps for the exercise, and then turn the next card over and move onto the next exercise.
When you are starting you may be unable to do a full deck of cards. No problem. Start with the number cards up to the eight. Add one more card at the beginning of each workout until you can use the full deck.
