Bird dog crunch is a core body exercise that strengthens the lower back and abdominals while helping your body learn to balance and find stability. This exercise will teach you to build a strong center while improving overall strength as well.

Here are the steps to performing bird dog crunch:

  1. Kneel on the mat on all fours. Reach one arm long, draw in the abs, and extend the opposite leg long behind you.
  2. Bring the elbow and knee in towards your center as you round your back remember to draw in your abs.
  3. Repeat for desired number of reps then switch sides.


The first tip in practicing bird dog crunch is to make sure you are on a mat or softer surface. Don’t pick something too thick or you will have trouble getting enough balance to perform the exercise.

However, make sure it is a soft enough surface that you do not aggravate your knee caps since you will be on all fours. (Much like a leg lift exercise.)

Another tip for this exercise if you have sensitive wrists is to close your hands and place your knuckles on the floor instead of open hands or hold onto some stable dumbbells that will keep your wrists in neutral position.

While you perform the bird dog crunch, try to be mindful of your breathing. Inhale as you tuck under and exhale while extending your opposite arm and leg out.

Make sure that as you extend your arm and leg you are tucking your belly button in to keep your back strong and stable. Another tip is to try and be as still as possible as you move. In other words, don’t let your back tip from side to side.
