You’re now halfway through Svava Sigbertsdottir’s 30-day fat-burning home workout challenge! Day 16 doesn’t require any equipment, so let’s dive in.

Today’s workout features sumo squats, high planks into downward dog, and side planks. These moves come with a twist to make you really feel the burn, especially in your core. Svava emphasizes controlling each movement to effectively build strength and stamina. If it’s not challenging, your core won’t work as hard, and you won’t get that toned look you’re aiming for.

When you start feeling tired, be sure to open up your chest and breathe deeply instead of falling forward, which can restrict your breathing. Keep your heart open and remember to keep moving.

Here’s the plan: spend 10 minutes on five moves, repeating the set twice. Do each move for 40 seconds, then rest for 20 seconds before moving on to the next one.

You’ve got this! Keep pushing through.
