Or does it?
Even for those "in shape" this fat burning workout is designed to reunite you with not just your abs - but your deeper core - and light that fire in your belly. So, be kind to yourself. We are building some serious strength here, from the inside out. With integrity! So it will seem a little hard at first. But don't give up! Even if you only do a little bit at a time, learn it like a vocabulary. This way you can slowly build your vocabulary and eventually have the ability to have an awesome conversation with your core strength. (You like how I did that there?)
Build your vocab and eventually you will know an awesome sequence that creates vitality in your core. If you do this I guarantee you discover parts of yourself that you never knew existed. Not to mention a happy healthy back and better working pipes!
Remember it is about the practice. Give it a try. Practice.
Good luck and love aways!
