Boot-camp gym rats $ocked

These ex-Marines must have forgotten that “semper fi” means “always faithful.”

Two former jarheads have been ordered to pay nearly $250,000 in damages for being “faithless servants” of a Manhattan gym modeled after military boot camp.

A judge ruled that fitness instructors Alexander Fell and Ruben Belliard “breached their duty of loyalty” to Pure Power Boot Camp by stealing corporate documents and sabotaging the business before opening a competing operation just blocks away.

But Manhattan federal Magistrate Judge Theodore Katz refused to shut down their rival Warrior Fitness Boot Camp, saying Pure Power’s trademark doesn’t give it “exclusive use of fixed obstacles and a military theme.”

Katz also let the pair off the hook for nearly $2.4 million that Pure Power claimed in lost profits.
