Dr. Malek recommends adding front planks into your routine two to four times a week to strengthen your core and maintain endurance of your core stabilizers.
Start face down on the floor resting on your forearms and knees.
Push off the floor, raising up off your knees onto your toes and resting mainly on your elbows.
Contract your abdominals to keep yourself up and prevent your booty from sticking up.
Keep your back flat — don't let it droop or you'll be defeating the purpose. Picture your body as a long straight board, or plank.
Hold for 30 to 60 seconds, and complete a total of three sets.
