Most people complain that their back and or neck hurt when doing crunches so here are a few quick tips to help you out.
Press the low back into the floor as if you are trying to touch your belly button to your spine. Keep your abs tight when crunching up and down, don’t loosen up when you go back down and just flop to the floor.
Continue pressing the belly button into your spine and your low back pressed to the floor. A little trick to get you out of the neck is to bend your head forward and use your chin to hold a tennis ball, a towel or something small between your chin and chest. If you are throwing your head all over the place this is an easy way to keep that head still.
One last thing is to stop going up so far with the movement. Abs are supposed to flex the spine not throw your torso off of the floor. Shorten the motion. If you feel your feet jumping off the floor or moving around you’re throwing from your back and trying to go up too far. If you find you are sitting on your tailbone at the top half of the exercise you are going too far. It is a crunch, not a catapult, just squeeze the abs and keep them tight, up and down, every repetition.
Hope these help!
