Cass Martin is an American fitness creator working the gym-editorial lane: sports bras, iron in the background, definition that reads competition-adjacent, and a platform row with no paid-content storefront at all.
The record is short and consistent. Facebook under her name, casssmartin on Instagram and Snapchat, thecasss on TikTok, cassmartin on YouTube — and that's the stack: no OnlyFans, no Fansly, no Patreon on file.
The gallery is wall-to-wall gym. One frame is shot like a supplement campaign — lime sports bra, hair swept up, leaning on a rack in moody depth-of-field with visible obliques and a composed three-quarter smile. The other is the working version: mirror selfie in a white bra and Nike sweats, ponytail, bicep curled toward the lens with genuine mass behind it, plates and dumbbells stacked into the background. SFW per our rating and per every pixel. If there's a training program or a coaching funnel behind this, the row doesn't capture it yet — flag for a future platform sweep, not for guessing.
