WATCH: Irish Olympian Fiona Doyle’s one-arm pull-ups put us all to shame

That's why she's an Olympian.

Our idea of pull-ups are very different to Fiona Doyle's. https://www.youtube.com/watch?v=OUW6hhDNkgQ The Irish swimmer heading for Rio this summer is a beast in the gym. She's actually taken our notions of tough work-outs in gyms up and down this country and she's laughed at them. https://www.instagram.com/p/2EQE9jvhFr/ The Limerick native is one of the stars of RTÉ's new Road to Rio documentary airing on Wednesday night. At 24, Doyle is coming into her first Olympics off the back of two medals at last summer's World University Games and it's easy to see that she's ready to compete. A sneak preview of Wednesday's upcoming episode shows the swimmer being put through her paces. Or putting the paces through their paces. Her intensity in the pool, her gym workout, her ridiculous ease at flinging herself up for one-armed pull-ups really makes you think about your own exercise regime. Prepare to feel bad about yourself. This is what competing actually looks like. https://www.youtube.com/watch?v=IL2z57rZWEU
