The comedian joked about the prank on the season finale of her podcast, 3 Girls, 1 Keith.

Raise your hand if you've ever done a workout that was so grueling, you briefly considered suing your gym, trainer, or class instructor for putting you through it. If you can relate, Amy Schumer feels your pain. On the latest episode of her podcast 3 Girls, 1 Keith, the comedian revealed that she had her lawyer jokingly draft a cease and desist letter to her personal trainer, AJ Fisher, after some particularly intense workout sessions.

Most people tuning into the podcast probably thought Schumer was kidding—but she wasn't. To prove to the world that she was, in fact, serious, the mom-of-one shared the actual cease and desist letter to her Instagram, which naturally went viral.

"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 exercise well outside the bounds of normal physical training," the letter reads. 

It continues by noting that Schumer was "unable to perform simple daily tasks like walking and picking up her child as a result of such exercise"—something pretty much anyone who's made it through a tough workout can relate to.

Then came the letter's official warning: "Your blatant disregard of Ms. Schumer's physical well-being can only be interpreted as a deliberate effort to cause Ms. Schumer emotional distress, potential physical injury and lost revenue. It may even be determined to be a violation of her human rights." (Related: 8 Times Amy Schumer Got Real About Embracing Her Body)

The letter ended with a note to Fisher saying that she should "cease and desist such torment" and alter her workouts to ease "such pain and suffering." (Related: 8 Ways to Override the Urge to Quit)

In her Instagram post, Schumer questioned if having her lawyer draft this letter was a waste of resources. "Very very much so," she wrote. "But it brought me so much joy."

Obviously, the whole thing was a prank and shared in good fun. Schumer even made it a point to note that Fisher is actually an "amazing" trainer. "[She's] the reason I feel strong and good and have recovered from my herniated discs and C-section," Schumer wrote.

ICYDK, Schumer has been open with fans about many of her health issues, including herniated discs she suffered as a result of old volleyball and surfing injuries. The new mom has also been candid about her challenging pregnancy: She not only experienced hyperemesis gravidarum (HG), an extreme form of morning sickness, but she also had to undergo a C-section unexpectedly.

Fortunately, Schumer seems to be recovering and getting back into a routine with her exercise, in large part because of her training sessions with Fisher, the comedian said in her Instagram post.

As for Fisher, she doesn't seem too upset by the cease and desist letter. In fact, she wrote on Instagram that it might just be the "best quasi-testimonial" she's ever received.
