Distance Lifestyle Coaching Service

In the past, due to the nature of our business, it has been necessary to physically engage with our clients on some frequent basis. This in turn has limited the scope of areas in-which we have previously been able to provide our services. However, with the advancements in telecommunication, it has become ever more possible to provide the level of quality service our clients have come to expect, to a much wider demographic area. We are very excited about our ability to help so many others, by utilizing our Distance Lifestyle Coaching Services.

Ron brings knowledge and integrity to the health & fitness industry

Ron began his career in the health & fitness industry, in the late 1980s. His interest in health & fitness grew as an amateur bodybuilder, training with some of the top physique competitors in the world. In 1991 Ron opened Baer’s Fitness, a 16,000 sqft full service fitness center, in Palmdale CA. In 1998 Ron Relocated to Orange County CA, and has been providing quality health and fitness services to the community ever since.

Ron recognized there was a need to do more in closing the gap between what the scientific community was showing in their research and what the general public was actually doing. Ron has made it his lifelong commitment to bridge the gap, by improving the communication between the scientific, medical community, and the general public. For the past 27 years he has pursued a tireless effort to expand his studies in the fields of life science to include; General medicine, pharmacology, neuroscience, virology, infectious diseases, immunology and exercise immunology, genomics, cell biology.

Ron believes, by understanding a top-down/bottom-up point of view of physiology, one might be able to capitalized upon certain principles which may be used to affect change in one’s physiology and behavior. In other words, by understanding genetics, molecular biology, cellular biology, systems biology and behavior, a clear picture is presented which maximizes the efficiency of making lifestyle modifications that in turn produce a higher quality of life.

Ron’s knowledge has afforded him the ability to address each individual’s needs and goals with an unrestricted and unbiased approach. He believes that in order to provide the highest quality of service possible, one must be able to help others obtain their goals as effectively as possible with the least amount of risk. His definition of a good trainer is one that is not bound by the equipment around him, but rather, by the ever-growing information and research available. Those who choose to train with ATP Lifestyle Modification, tend to be the very best in their field and demand the same. Ron is committed to an endless pursuit of knowledge in the fields of life science, and to the ability to transform that information into meaningful and real results for others in order to improve the quality of their life.
