Want six-pack abs? Nikki Fogden-Moore demonstrates the 90-degree crunch with raised feet.

 

Once again we get back to basics! The wonderful thing about this crunch is that you are engaging those lower abs and keeping that tension while working the upper abdominals. It’s a great exercise to build up any lower abdominal weaknesses and a great base for more technical or advanced abdominal work.

How to

Start in the classic crunch position, raise your feet off the ground, aligned so your knees are 90 degrees.

Pulse up to the sky with your eyes up and chin off your chest, keeping the tension on your lower abs and your head supported.

Remember to keep your elbows back as this automatically helps you avoid pulling on your head and straining your neck.

Do 20 to 25 reps. Rest and repeat 3 times.
