Your core is comprised of many muscles but most people think it only refers to the six pack muscles. The six packs actually aren't the most important core muscle we have. If you've read my other articles, you know the most important muscle to strengthen is transverse abdominus, otherwise known as TA. TA is the foundation of our center and is what grounds us. If this muscle is weak it doesn't matter how many six packs we have, we will be missing a big piece of core strength puzzle!
