You’re now halfway through Svava Sigbertsdottir’s 30-day fat-burning home workout challenge! Day 16 requires no equipment. Let’s dive in.
Today’s workout includes sumo squats, high planks into downward dog, and side planks. These moves are designed to make you sweat with a twist and really get your core burning to build strength and stamina. If it were easy, your core wouldn’t have to work as hard. It’s supposed to be challenging to get that toned body you’re aiming for.
When you start feeling tired, remember to keep your chest open instead of falling forward to catch your breath, as this can restrict your breathing. Always open your chest and breathe deeply.
You’ve got this. Keep pushing through. The session is 10 minutes long with five moves, done in two sets. Perform each move for 40 seconds, followed by a 20-second rest. Then, repeat the sequence one more time.
