Maybe not as good as Bad Santa or that one with Ralph who wanted the BB gun but those are movies that everybody's already seen. Not everyone has seen Santa's Slay yet. The intro alone is one of the greatest scenes ever filmed. I rented this movie once from Blockbuster and liked it so much that I just never took it back. Fuck Blockbuster anyway. But I don't know where that movie is right now so I have to watch it on Youtube.
Since it is Christmas Eve I guess I'll give you something.
Using a regular deck of cards.
Turn one card. This is how many sets you're going to do.
Before each set you turn another card and that will be how many reps you're going to do. A Joker is a set to failure.
Beyond that everything else is up to you. You can take as long or as short of rest periods as you want. You can change weights between sets, or not. You can even change exercises or exercise variations between sets. It might not seem like it just reading about it but it's a pretty versatile game.
For the advanced version, the first card you flip is going to be how many exercises you'll do. Then you continue as you normally would, flipping for sets and reps on each exercise. On an unlucky day you might end up doing 10 exercises for 10 sets each so save it for a weekend or any night when you know you've got it pretty easy the next day at work.
If you don't have a deck of cards around, buy one at the fucking dollar store. What's wrong with you? In the meantime you can use dice.
I did. I think I had two or three sets of them for a while. I don't know where they are now though. I even had the 100-sided die, which was totally fucking useless.
Anyway there you go. And if you're feeling particularly badass, or you're just limited on weights, you can use the dice or cards to decide how many minutes a set will last rather than how many reps. Entirely up to you. You can't cheat at this game. I do recommend that you try though.
Happy birthday tomorrow!
