Expect Great Results with our Glendora Personal Trainer

If you want to look great, lose weight, and firm and tone your muscles, consider hiring David, our Glendora personal trainer from the High Performance Personal Training Team. With personal trainers available in Glendora, Pasadena and Los Angeles, we have one that is close enough to your location. We will develop a program that will help you get in better shape than you ever thought possible before.


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.

In addition to personal training at David’s Glendora personal training studio or our Santa Monica headquarters, we also offer the following fitness related services to address all your health and fitness needs:
