Emer O'Neill: Keep It Up

Six-part docu-series: basketball star and Ireland’s favourite PE teacher Emer O’Neill’s theory is put to the test as she brings together nine teenage girls who have either given up sport or never played. More than half of girls playing sports in Ireland drop out by the time they are 14. Puberty, bullying, crop tops, cliques, team sport v singular sports, smelly dressing rooms, and spray tans, everything is discussed.
