Oritse has gone on a special diet of "clean foods" and water for maximum pecs appealJLS star Oritse Williams has gone on a special diet for the group's European tour.
The 25-year-old singer has created his own menu of "clean foods" and he has taken up a strict exercise regime of Bikram yoga and martial arts to ensure he stays in shape for all the boy band's 4th Dimension concerts.
He said: "I've set myself a new diet where I eat clean foods and only drink water six days a week. I also do Bikram yoga and martial arts."
Fitness fanatic Oritse is obsessed with burning off any alcoholic drinks he consumes and during a recent trip to the US with the group - which is also made up of Marvin Humes, Aston Merrygold and J.B. Gill - he went to the gym at 3am after spending the night partying in a club.
He added to the Daily Star: "When we were last in America I thought, 'If I have an alcoholic drink, I'll need to burn this off,' so went straight to the gym at 3am after being in the club."
As well as their 4th Dimension tour, JLS have been busy planning Marvin's stag party with the help of a former MI5 secret agent ahead of the 26-year-old singer's summer wedding to The Saturdays' singer Rochelle Wiseman.
