The High Performance Personal Training program

I designed the High Performance Personal Training program for the thousands who have been disserved with the offerings of most fitness club and of the in-house personal training programs like those found at other gyms, with other trainers, and online. Hula-dancing classes, spinning and piloxing are not going to get you the body you’ve always wanted. A head above the rest, my High Performance Training program combines results, ease and personal attention. We strive to offer you the experience you’ve never had before and deliver the results you most likely didn’t know were possible.

After 4 years living in hotels, working way too hard and working out way too little had resulted in what I thought was an extra 10 – 15 pounds that I just couldn’t get rid of no matter what I tried. When someone enquired when I was due I realized it was time to really do something about it. Jason Kozma was the answer. In 8 weeks Jason gave me a better body than I had ever had before. 10 – 15 pounds turned out to be 25 pounds and the six pack I had only ever fantasized about became a reality. Jason’s combination of weight training and his amazing diet (he actually had me eating 3 times as much as usual and dropping pounds by the day) is the quickest, healthiest way I know of to guarantee the body you’ve always wanted. The effects of training with Jason and the new body that came with it have enhanced every aspect of my life…I can’t recommend him highly enough. Not to mention he has you laughing the whole way through it.

Team Leader Jason Kozma is a former Mr. America who is based out of Santa Monica. He has more than 20 years of experience helping clients lose weight, increase their performance in sports, and decrease body fat. Jason works with men and women alike, structuring his approach differently in order to help each person meet his or her individual needs. While men normally prefer to get ripped abs and build muscle, that’s not always the case with women, and Jason can help ladies lose fat, get back in their “skinny jeans”, become firmer and stronger while still looking feminine and curvaceous. For those men women who do want a more muscular appearance or even compete, Jason can help them achieve those goals as well.
