Planks are a great way to strengthen your core! To do a plank, start by getting into a push-up position with your elbows directly under your shoulders. Keep your body in a straight line from head to heels, engaging your core to hold the position. Breathe steadily and try to hold it for as long as you can. Have you tried planking before, and if so, what's your current plank time? It's always fun to see improvement!
