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 into downward dog, and side planks, each with a twist to really make you sweat. Control every movement to feel the burn in your core, building both strength and stamina. If it were easy, your core wouldn’t benefit as much. It needs to be challenging to help you achieve that toned body.

When you get tired, avoid leaning forward to catch your breath, as this can restrict your breathing. Instead, make sure to open your chest and breathe deeply.

You’ve got this, keep pushing through.

Here’s the plan: 10 minutes, five moves, two sets. Perform each move for 40 seconds, followed by 20 seconds of rest, then repeat the sequence one more time.
