    Frog Crunch

    Froggy Crunch or Frog Crunch is an abdominal exercise that strengthens the rectus abdominus and helps flatten your abs. Similar to a regular crunch, your legs remain on the ground while you flex you upper body up and down off the floor. The primary mover of this is your rectus abdominus- your six-pack.

    The difference between frog crunch and a regular crunch is that your legs are open in a diamond shape with the souls of the feet touching and the knees splayed out to the sides looking like frog legs. So what are the benefits of putting your legs in this position? With the legs opened up and relaxed you are less likely to tighten your quads and hip flexors and use them over and above using your abdominals.

    If you learn how to do froggy crunch you will have a new way of performing an abdominal crunch. With this new form you will be more likely to do a crunch properly. So many people perform crunches incorrectly. Often crunches get a bad rap mainly due to this factor. Of course crunches by themselves– or any ab exercise for that matter – will not solely flatten your belly. Eating clean and getting in your cardio exercise is part of getting flat abs since it reduces the fat that covers your belly in the first place. However, done properly abdominal crunches are one of the best moves you can do to build core strength. Froggy crunches will teach your body the proper form.

    Here are the steps to performing frog crunch:

    1) Start lying on mat with fingers at the base of your head and elbows pointed out. Bring the soles of your feet together, knees pointed outward.

    2) Tilt your chin slightly forward and squeeze abdominals to lift chest upward.  Keep arms and neck relaxed.  Slowly lower down and repeat.

    Targets: core
