The stronger your core, the more stable your spine. Period. In my experience as a Chiropractor, patients who have the strongest core, generally have fewer back problems…let that exclude those who do a whole lot of ‘dead-lifts’ with heavy weight (that can create a host of back injuries). Stronger core muscles help your body stay in alignment as well! My favorite core strength exercise is the plank.
**If you have a very weak core, try this same form only go to your knees instead of your toes.
Here are some things to consider, if you want to remain in good form:
DO broaden your shoulders
DO tuck your butt in a little and squeeze
DO take deep breaths in as you contract your abdominal and back muscles
DO keep your head and neck neutral, looking toward the floor
DO NOT arch your back
DO NOT lower your hips too much
DO NOT look up in front of you
