Crunch Gym is squeezing its personal trainers — paying the fitness instructors just $8.75 an hour for one-on-one sessions and refusing to compensate them at all for other duties like meetings and cleaning, according to a new class-action lawsuit.

Arielle Jernigan, who worked at the East 59th Street location from 2015 to 2016, and Kadeem Johnson, who is still employed there, filed the suit in Manhattan state court on behalf of 30 to 40 other Crunch trainers.

Their suit says they weren’t paid for 15 to 21 hours of work each week, including attending lengthy meetings, cleaning weights and organizing the gym.

The practice violates state wage laws, according to court papers.

They’re suing for up to $200,000 in lost wages, plus additional damages.

Crunch did not return an e-mail requesting comment.
