When it comes to getting into shape for Jason Baer, it's personal.

The Easton resident recently opened a fifth Personal Trainers Professional outlet in Greenwich 12 years after founding his first location in a 3,000-square-foot space at 28 Vitti St., New Canaan.

"We feel the demographic is good for the services we provide, and our clients kept asking us when we'd be opening in Greenwich," said Baer, who last month opened a 3,000-square-foot location at 469 W. Putnam Ave., Greenwich. "We hope to expand into the Westchester County area as PTP of Greenwich gets going."

Baer, who has a degree in exercise science, in 2008 opened PTP's second venue at 5 River Road, Wilton, and then in 2009 sold two franchise locations at 3683 Post Road, Fairfield, and 105 Danbury Road, Ridgefield. Start-up costs for PTP franchise range from $125,000 to $200,000, Bauer said.

A challenge to opening such a franchise is it may require a bit of salesmanship from personal trainers, said Steve Dubin, president of the New England Franchise Association.

"Sometimes those skills don't mesh well," he said.

The five locations, which employ about 50 employees total, have provided customized personal training regimens involving exercise, pilates, nutrition and massage therapy to "thousands of clients," Baer said. The Greenwich location, which was established with directors Michael Jordan, of Norwalk, and Matthew and Kristen Caron of Trumbull, will have three personal trainers, two pilates instructors, a registered dietician and two massage therapists to provide PTP's services, he said.

"All programs are custom-designed to the individual," he said.

Patrons may also use PTP's cardiovascular equipment 6 a.m. to 9 p.m. Monday to Friday and 6 a.m. to 3 p.m. Saturday and Sunday, Baer said.

Training regimens are given in 10, 20 or 30 hourlong sessions following a free required consultation, said Baer, who declined to give costs.

Despite the slow economy, business has been steady as most of PTP's clients have kept fitness high on their priorities, Baer said.

"They made cuts in other areas, so we were not overly-affected," he said.
