Amy Schumer sent her personal trainer a cease and desist after she was subjected to “extreme and unduly punishing” workouts

In an episode of her ‘3 Girls, 1 Keith’ podcast, she was joined by AJ and celebrity trainer Harley Pasternak, who has also trained Amy in the past.

And Amy clearly prefers one trainer over the other, as she said: "AJ, our workouts were so hard that I threatened you near constantly.

"I did have my lawyer, Isaac Dunham, send her a cease and desist. This is the guy I bought bench ads for without his permission, so his face was on benches for several months.”

The ‘Trainwreck’ star had the cease and desist letter on hand to read out, which jokingly claims AJ gave her exercises that were “well outside the bounds of normal physical training”.

Reading out the letter, Amy said: "He said, 'We are the attorneys for Amy Schumer, an internationally known actress, comedian and high-profile public figure. It has come to our attention that while Ms. Schumer has engaged you to perform simple physical training for her, you have instead forced Ms. Schumer to perform extreme and unduly punishing physical exercises well outside the bounds of normal physical training.' I mean, it goes on and on.”

And whilst AJ knew the threats of legal action were in good humour, the letter did make her panic that her career might be “totally over”.

The trainer said: "Amy told me after several of our sessions, 'You will be hearing from my lawyer.’ Like, without even saying bye. And then, when I finally heard from her lawyer, I opened the letter and I actually got goosebumps. I had a moment of, 'Was she serious? Is my career totally over?’ ”
