Every time we see a picture of Cameron Diaz rocking a bikini , we're wowed by her strong and svelte physique! Her longtime trainer (and KIND Snacks  spokesperson) Teddy Bass has one move he recommends to anyone looking to whittle her middle and reshape her core: the trusted plank. While exercises like crunches and reversed curls target specific areas, says Teddy, the beauty of planks is that they work your entire core, from your pelvis to your obliques and all the way up to underneath your rib cage.
There are so many different variations of plank , but Teddy's go-to pick for beginners is the elbow plank for 30 to 40 seconds. To make the most of your time in this exercise, it's essential to keep your body in a straight line from your shoulders all the way to your heels and to "stop praying !" According to Teddy, when your hands are together in plank, you're hindering your body's ability to achieve a great posture like Cameron's — a beautiful benefit of this no-equipment move.
