You’re now halfway through Svava Sigbertsdottir’s 30-day fat-burning home workout challenge! Day 16 is all about using your body weight, so no equipment is needed. Let’s jump in!

Today’s moves include sumo squats, high planks into downward dog, and side planks. These are designed to make you sweat and keep things exciting. Make sure to control each movement to really feel the burn in your core, helping you build strength and stamina. If it were easy, your core wouldn’t get much of a workout, right? That’s why it has to be challenging—it’s the path to a toned body.

When you start to feel tired, remember to open up your chest and avoid slumping forward. This helps you breathe better and keep going strong.

You’ve got this—keep moving! The routine is simple: 10 minutes, five moves, done in two sets. Do each move for 40 seconds, followed by 20 seconds of rest, and then repeat.

Now let’s get it done!
