I don't think it's likely, and it's likely not even possible. Jay is quite a bit shorter than Renne (5'3" compared to 5'8"); Jay is also already 54. Toney had 20" biceps when she was 30. Korableva and Kuznetsova are more likely contenders, being taller (5'6" and 5'7", I think) and having already joined the ranks of the largest woman bodybuilders while still in their twenties.
Why should she do that, and what does she gain from it?
She claims this on Instagram, and this claim can also be seen in the photos.
She has always seen herself as a mega superstar, but in her last official competition, she totally disappointed her fans, supporters, and sponsors. I think she is now looking for validation for herself. I think she has proven in her latest photos that she is capable of much more... but I think the 20 inches could also be just silly talk again. She recently publicly insulted her fans and sponsors and increased the price of her OF account to 50 euros/month. I have no idea what her expectations are now?!?
I wish her to reach 20 inches, but I think that when she soon leavs the off-season phase, her 18 inches will quickly turn into the usual 16 inches. I think we will see wonderful, hard on-season photos of her.
With actual muscle? No.
With injectable oils, creative camera angles, and a lot of exaggeration? Sure.
Which is honestly fine. She's presenting a fantasy. If it turns you on to imagine that she has 20+ inch biceps, then why the hell not?
As she mentions on her social media, she is now working on achieving 50 cm biceps. In October 2025, I had a private session with her, and I measured her biceps in 43.5 cm. She's added more than 3 cm to her biceps since then. Who knows, maybe she'll get very close to 50 cm in the off-season.
Jaqueline has set herself the goal of achieving a 20 inch biceps (min. 50 cm | ~19.6 inches). With 20 inch biceps, she would be in the same league as the unique Renee Toney.
At the moment, Fuchs seems to be stuck at 46-47 cm (~18+ inches).
Do you think she will achieve 20 inches?
A comparison between Rennes' 20+ inch biceps and Ms. Fuchs' 18+ inches (The measured arm is true to scale).
