Matt is a professional. I came in bloated, weak and pre-diabetic. After 4 weeks my body is changing in ways I had only imagined while sitting on the couch eating chips, watching PX90 commercials. With high school knee injuries and a hernia from being fat, Matt has customized my workout to not harm me, but build a strong core. My wife is now giving me that same look she did 10 years ago, and, ahem... its been GOOD. My kids no longer call me "fatty daddy". I am 41 and this has been the best investment that I've made in myself in years. I highly recommend Matt. This is by no means a magic bullet, but 30 minutes 2x a week has changed me from dud to on my way to stud!
