This first exercise challenges your core strength and stability. The plank is one of the best ways to tone your midsection and strengthen it so you can handle whatever life throws your way. It's also an exercise that doesn't take much time to improve on. After doing this workout just a couple times, it'll feel so much easier to hold a plank and you'll literally feel your core getting stronger.
Konforti's Trainer Tip: "The most important part of any exercise and especially the plank is alignment. For the plank, you'll start on your elbows than lift your body up so your neck, shoulders, glutes, and heels make one straight line. Be sure not to make a tent by poking the hips up or make a hammock by letting your hips drop. Staying aligned ensures that your core is doing the work and getting the results. To make it less intense, drop down to your knees, or up the ante by walking your elbows out past your shoulders," said Konforti.
