In the final episode of Jessica Fostekew's stand up series about big strong girls, we arrive at the most aesthetic and least functional of all the strength sports - bodybuilding.

The Schwarzenegger in swimwear one.

It's an area in which Jess is way out of her depth, having flirted with the weightlifting movement by accident over the years but never daring to face the gruelling diet.

Luckily she's got two brilliant interviewees on hand to help her get deep into the nitty gritty of things - champion bodybuilder Frances Amies-Winter and actor and former bodybuilder Megan Prescott. We also find out about the history of the sport as part of circus tradition, and Jess goes to Fran's gym to train with her on leg day.

Yes. She can just about still walk now.
