All you need for this workout is this photo, a kettlebell or dumbbell, and a deck of cards.
Complete 10 burpees to get into the game. Guess whether the first card in the deck is red or black. If you guessed correctly move onto goblet squats (the next exercise on the tree). If your guess was wrong repeat the burpees before starting the process over. See how far down the tree you can get in 30-60 minutes. If you get all the way down the tree complete as many rounds as possible of the abs exercises in the trunk of the tree with the remainder of your time.
