How to: Lie on your back with your legs extended out in front of you. Place your arms by your sides, palms down. You can also alternatively bend your elbows so your upper body is resting off the ground. Engage your core by pressing your lower back into the mat. Lift both legs off the ground about 6 to 12 inches from the the floor or about a 45-degree angle. With your core tight and neck relaxed, lower one leg toward the floor as you lift the other leg up. This is the start of the “scissoring” motion.
3Forearm Plank
Drazen_//Getty Images Don-A-Matrix likes this classic move that can be a bit more challenging than the traditional straight arm plank since it recruits a few more essential core muscles.
How to: Place forearms on the floor with elbows aligned below shoulders and arms parallel to your body at about shoulder width. Ground toes into the floor and squeeze glutes to stabilize your body. Your legs should be working, too; be careful not to lock or hyperextend your knees. You can either hold the move, or step your feet out one at a time for a greater challenge.

How to: Lie flat on the floor with your arms and legs extended. Take a deep breath and as you exhale, contract your abs and simultaneously raise your right leg up to the ceiling and your opposite left arm to touch your right foot. Lower back down slowly, and repeat on the other side so that your opposite hand touches the opposite foot.
5Bear Plank Walkouts

How to: Start on all fours with your back flat, wrists directly under your shoulders, and knees bent resting on the floor. Engage your core and lift your knees, allowing them to hover a few inches off the ground. Step back into a traditional plank with your legs straight, and then step back into the bear plank position.
