CozmoSize Fitness

My son started with Matt his Freshman year of high school. Matt educated my son about lifting and nutrition. Matt’s attention to form and constant positive encouragement made him have a strong, healthy and knowledgeable work ethic all together.

Hands down the best personal training in the valley! There’s plenty of high end equipment that will help you reach all of your physical goals!

Matt is the best! His dedication to his clients and the results he gets for them are incredible! My daughter's two CIF high school championships wouldn't have happened without Matt and CosmoSize.

I've been a member for quite a while, and I've noticed a dramatic change in my athletic strength and ability. Matt is a great coach, very knowledgeable and friendly. He will tailor any workout according to your ability.

I started up at Cosmo Size about 4 months ago and I’m not looking back. Matt is an awesome person and definitely 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!
