Lie face-up on a mat grasping something overhead or your arms flat at your sides. Pull your legs up so that they are at a right angle with your torso. (Theresa Hessler demonstrates at top of page.) This is your start position. Keep the position of your legs as consistent as possible. Now curl your hips up to the position shown in the second photo while exhaling. Your weight should be concentrated on your shoulders, not your neck. Slowly return to the start position while inhaling.
Start on the floor with your feet outstretched (more difficult) or your knees slightly bend with your heels on the floor (a bit easier). Contract your core, lift your upper body from the hips so your lower back and shoulders are about 10 inches off the floor. Stretch your arms out along your sides with palms up, and simply hold that position for up to a minute at a time. Ouch. It's a good one.
Your core muscles allow you to stabilize your spine when you do pushups, shovel snow, walk up stairs, pick up your kids from the floor, and otherwise go about the motions of everyday life. "That's why the best ab exercises don't flex your spine, they keep your spine straight," says Durkin. The hip-up does exactly that while also sculpting your obliques and increasing your rotational control and stability.
For example, believing that you should eat your pre-workout meal is a great way to procrastinate with your training. What if you worked overtime and you don’t have enough time to eat your pre-workout meal? What if you don’t have enough money to buy supplements? All the items in the above list have the potential to evolve into excuses for procrastinating, or worse, quitting. Just forget about them and only do what matters. This will save you enormous time and willpower that should be spared for the things that actually matter in your quest to get abs.
To do it: Stand with your feet planted 3-4 feet apart, toes slightly turned out, hands on your hips. Lower into a plie by bending your knees out over your toes and lowering your hips directly underneath your shoulders. Then, as your straighten back up, slowly lift the right knee up towards the right shoulder. As you go back into the plie, slowly return the foot to the floor. Be sure to move at a very controlled pace to really engage the obliques the entire time—on the way up and on the way down. Do 10 repetitions on the right side, then another 10 repetitions on the left side for a total of 20.
