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 includes sumo squats, high planks to downward dog, and side planks. These moves have a twist to really make you sweat. Focus on controlling each movement to feel the burn in your core, which will help build strength and stamina. If it were easy, your core muscles wouldn’t be working hard enough, says Svava. The challenge is what helps you get that toned body.

When you start to feel tired, remember to open up your chest and breathe deeply instead of slumping forward. This will help you keep your breath steady.

You’ve got this! Keep moving.

The workout consists of 10 minutes, five moves, and two sets. Perform each move for 40 seconds, followed by a 20-second rest. Then, repeat the sequence once more.
