Want to learn a new card game? The rules are easy. Turn a card over, do 10 press ups. Turn another card over, do 10 more press ups. Turn a card over, do 12 burpees. Another card, six burpees. And another, nine burpees. Exhausted yet? Want to keep going?
This is exactly how workout app Sweat Deck works. It asks you to assign an exercise to each of the four suits in a deck of cards. You have a long list of exercises to choose from so you can design your own workout, and if you upgrade to the pro version, there's an even longer list plus the ability to add your own exercises.
You then have two customisable joker cards, which you should obviously use to challenge yourself. (Yes, we see you writing, “Rest for 30 seconds”. Tut tut. You can do better than that. Try “Double-under skipping – one minute” instead.) Are you ready? You have 54 cards to get through, all against the clock.
If this sounds a little gimmicky, wait until you’re halfway through a pack of cards, having just turned over a king followed by an ace, followed by a jack, followed by a nine all of the same suit.
Depending on how you set up your deck, that essentially means you could have just done 40 narrow grip push-ups in a row. Take our word for it: it burns. We promise you won’t be underestimating the seriousness of Sweat Deck once you try it.
