The cardio core crawl is a dynamic, multi-joint exercise that targets the core, hips, and glutes. The exercise also strengthens the lower back and shoulders.
Start on your hands and knees. Keep your core tight and maintain a slight arch in your back. Lift your knees an inch or two off the floor so that your weight is on your hands and feet.
Step one hand forward and simultaneously bend your opposite knee up to your chest. Return hand and foot to starting position. Then step forward with your other hand as you bring the other knee up to your chest. Return to starting position.
Don't allow your lower back to collapse at any point.
Pull your abs in tight and brace your core throughout the exercise.
Keep your head in line with your spine and upper back at all times.
