Pained lawyer sues trainer

Guess he never heard of “no pain, no gain.”

The exercise routine that gave Beyoncé her banging bod was too much for a scrawny Manhattan lawyer, who’s suing a Chelsea personal trainer, claiming the workouts left him in constant pain.

Three years after several intense sessions of squats and thrusts with a Focus Integrated Fitness trainer, attorney Neil Squillante still suffers “pain and weakness when he stands,” and has trouble sitting “for reasonable periods,” according to a lawsuit he filed yesterday against a personal trainer, his boss and the company.

As a result, Squillante said he schedules few meetings, rarely travels, is unable to recruit workers, and has a diminished social life.

Squillante’s woes began in April 2010, the suit says, when he met with Focus co-founder Gabriel Valencia, whose clients included “Get Me Bodied” singer Beyoncé.

Squillante “lived a sedentary life with minimal physical activity, lacked physical strength and fitness . . . and had no experience with vigorous physical exercise or strength training,” the lawsuit says.

But instead of a mild workout, Squillante said he got a torture session.

“Within a few days after his first physical training session, Squillante told Valencia by telephone that his arms were so sore from the workout that he could not lift them,” the lawsuit said. “Valencia chuckled and said that Squillante’s soreness was normal and nothing to worry about.”

The lawsuit does not describe the exercises, but in a Focus promotional video featuring Mrs. Jay-Z, the hip-hop diva is shown doing leg raises for her abdominal muscles, and pelvic thrusts from a large ball for her buttocks.

She also does double-handed jabs with a medicine ball to tone her arms.

He went to two more, then canceled a fourth because he could barely move, he says. Three years later, he says he’s still in pain.

Squillante did not return calls for comment.

Valencia and the personal trainer, Brent Carter, also did not return calls for comment.
