• Jaron I., a 24-yr old elite cyclist who previously had developed exertional rhabdomyolysis after an intense training ride.

"By the way, I only paid for a month with the thought in mind that I'd limit my losses if this was yet another disappointing falling short of all that was advertised. Well, Stan, I'm already beginning to feel like I'm getting way more than I deserve for what I paid. Thanks again and again." August 2, 2008.

• Clay R., a 58-yr old man with multiple medical problems.

"I'm reading the articles you've written and suggested and I feel like I'm 'on my way.' I could not have begun without your guidance and expertise. But equally as important is your continuing to be there. I need it. I really want to introduce fitness training into my permanent lifestyle and keep it that way." July 27, 2008.
