Ryan Harbrecht struggled to lose weight on his own for nearly his entire life.
"My knowledge of working out is very limited. No real guidance, no real goal setting, just that desire to change, but no action behind it."
The weight just kept piling on. He eventually got up to 375 pounds.
"There was also a lot of depression going on."
Desperate to get healthy - physically and emotionally - he hired a personal trainer.
"It's about the dealing with the personal issues, personal obstacles and setting something up that meets them at their place of need, and then following up over time," says personal trainer Cris Dobrosielski.
The demand for personal trainers is growing. The number of fitness instructors is expected to jump almost 25% over the next decade.
Dr. Cedric Bryant from the American Council on Exercise believes the spike is directly connected to the nation's obesity epidemic.
"No doubt, personal trainers are seeing more obese individuals and individuals who are suffering from a variety of obesity related conditions."
But sticking with it has been tough for Ryan. He quit his workout program for more than three years before coming back.
"It's not happiness in a pill its not, um, going to a doctor and having something done. It's really sticking for the long haul and getting it done in a healthy fashion."
Since March, Ryan has lost two inches from his waist and added healthy muscle. His goal is to lose 50 pounds over the next year but says he's more proud of what he's gained in the process.
Ryan's excessive weight is also taking a toll on his health. He has metabolic syndrome which puts him at risk for heart disease.
