You’re halfway through Svava Sigbertsdottir’s 30-day fat-burning home workout challenge! Today is Day 16 and you won’t need any equipment, so let’s dive right in.

Today’s exercises include sumo squats, high planks into downward dog, and side planks, all with a twist to get you sweating. You’ll want to control each movement to really feel the burn in your core. Remember, if the exercises feel too easy, your core isn’t working hard enough. That’s why it needs to be challenging to help you build that strong, toned body.

When you start to feel tired, focus on opening up your chest instead of falling forward. This will help you breathe more easily. Keep your chest open and take deep breaths.

You’ve got this—keep pushing through! Here’s how to do today’s workout:

-10 minutes total
-5 different moves
-2 sets of each

Do each move for 40 seconds, and then rest for 20 seconds. Repeat the sequence one more time.

Good luck and keep moving!
