Charlie has always been a ladies' man. That is to say, he was raised by a house full of women. His mom, who served in the military and put herself through college, passed that inner motivation on to Charlie. So when you hit the bag, he wants you to ignite your inner wildfire. Should you need help finding it, he'll get you there.
Seeing his clients reach their goals makes him do backflips. Literally. With his gymnastics, bootcamp, TRX, cycling and running backgrounds, Charlie is basically Superman. But every Superman has his kryptonite. Charlie's is tickling. Do. Not. Tickle. Superman.
