"Flexible, accommodating, encouraging and knowledgeable. All qualities that lead to consistent results for me even as my fitness goals change."
- Maria Perez
"I started up at Cosmo Size about 4 months ago and I’m not looking back. Matt is awesome and knows what he’s talking about in terms of working your muscle groups together. I’ve lost weight and improved my muscle definition, and I don’t feel like I’m doing the same monotonous workouts over and over. Working out is fun again!"
