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 jump right in.

Today’s moves include sumo squats, high planks transitioning into downward dogs, and side planks. These exercises are designed to make you sweat while adding a small twist for some extra challenge.

Make sure to control each movement to really target your core, building both strength and stamina. If it were easy, your core wouldn’t be working as hard, says Svava. Remember, challenges lead to that toned body you’re aiming for.

When you start feeling tired, try to open up your chest instead of hunching forward, as this can restrict your breathing. Keep your chest open and focus on your breath.

Stay motivated and keep moving. The routine is 10 minutes long, consisting of five moves done in two sets. Perform each move for 40 seconds, followed by a 20-second rest, and then repeat.

You’ve got this! Keep pushing through the challenge.

Svava’s book, “The Viking Method,” is available on Amazon in both the US and the UK.
