Video: Olympian Fiona Doyle completes one-arm pull-ups with ease during rigorous training
Irish swimmer Fiona Doyle will be giving it everything when she takes part in the 200m breaststroke at the Rio Olympics in August.
The 24-year-old combines work in the pool with a tough gym and running regime to attain her best performances.
The Dubliner's current personal best stands at 1.07.15, clocked in Korea last June as she swam to bronze in the World University Games.
Doyle was filmed for the RTE documentary Road to Rio which airs on Wednesday night and just watching this teaser would make you tired.
Her mastery of the one-arm pull-up is particularly impressive.
