A plus-size woman has spoken out after she was ruthlessly mocked for filming videos of herself at the gym.

Bethy Red took to her TikTok account on Thursday, August 12, to open up about how she was bullied by a woman who confronted her over recording her workouts.

According to Red, this woman said: "Girl, what are you doing? Are you taking videos of yourself?"

Take a look at Bethy Red's original video here:

In the video above, Red testified that was recording herself for fun. Her critic then added: "You are? Well, why? For your own documentation or what?"

When Red replied to her that the videos were for her blog, the woman apparently laughed in her face and said: "Good luck."

Red edited the footage of her encounter with the woman - covering her with a white square so that her appearance could be kept secret.

Yet a number of other TikTok users were clearly outraged by this woman's attitude, taking to the comments section to share their support for Red.
