In two years, Seaside Crossfit has moved from its owners' garage in Marion, to a warehouse, and now, with more than 100 members, to the Wareham Industrial Park.

Owners, trainers, and husband and wife Matthew and Jennifer Christopher relocated the business to Wareham this month, but the idea sprouted when Matthew returned from Iraq.

Matthew served as a captain in the U.S. Army, and Crossfit's physical training routines helped him and his fellow soldiers stay in fighting shape.

"I was exposed to this in 2007, 2008," said Matthew. "The army switched to this program."

Matthew and Jennifer started training two to three people in their garage with the rigorous program in the fall of 2011.

Crossfit isn't about losing weight — although it's a likely side effect. It's about becoming stronger in every aspect possible. Strength, flexibility, agility, endurance, balance, and more are worked upon in an intense workout that can be scaled to anyone's ability.

"The beauty of it is it's infinitely scalable," said Jennifer. "I could have grandma next to an elite athlete."

Jennifer ran Division 1 track at UMass Amherst and says that when she started doing Crossfit, she realized that while her body was specially trained to run fast and leap over hurdles, other areas had been neglected.

"We don't specialize" on isolated muscle areas, Matthew explained. "Nature doesn't reward the specialists."

Rachel Hallett, a 28-year-old gymnastics coach, tried Crossfit for the first time earlier this month. She said Crossfit gave the intense workouts she did when she was gymnast herself a run for the money.

"It's very similar," said Hallett. "I would say it's a little bit more intense."

Thirty-nine-year-old Jen Moura has been with Crossfit since the workouts were in the owners' garage, was partway through losing 120 pounds when she began.

"I was running a lot and it just got boring for me," she said.

Since beginning Crossfit, she said, her goals don't involve a number on a scale that can change minute by minute, day to day, but instead on conquering tough workouts.

"My body changed," Moura said. "Had I kept running I'd probably be lighter, but that's not my goal."

Seaside Crossfit offers the first class for free, and in addition to adult workouts, there are programs for children and teens ages five and older.
