Terroll Lewis has lived a crazy life. Growing up on Brixton's Myatt's Field estate, he was surrounded by gang culture, and like so many other young people, he found it hard to resist the lifestyle. By the time he was 15, he had already joined a gang, been stabbed, shot at, and was selling drugs.
A chance to play professional football offered a way out, but the lure of an easier life - the promise of girls, money, and cars - led him back to South London and the notorious OC, or Organised Crime, gang.
Violence and drug dealing were the norm in OC, but Terroll has long since turned his back on this world, though the association with OC endures through the ink on his skin.
These days Terroll's giving something back; Block Workout, a street-gym he founded in his old neighbourhood, gives young men an opportunity to follow a different road to the one he took during his adolescence - helping them develop their minds as well as their bodies - and the chance to live a better life.
