Marnie Swindells is the queen of mental strength; she’s a champion boxer, a qualified solicitor, a boxing coach, and now has opened her own community gym, having won a quarter of a million pounds on this year’s Apprentice. She talks to Karan about how she created her own success, how she copes with pressure and stress - and what motivates her to keep going every single day. This episode also talks about boxing and injury - what exactly is concussion, how you can avoid it and the benefits of boxing for fitness.
