Supplements brand Protein World has announced a new partnership with US TV personality Khloé Kardashian, who will share her fitness secrets for the Protein World 30 Day Challenge.

People who sign up to the challenge will be able to watch exclusive full body workouts, and have access to a comprehensive meal planner. Kardashian commented 'I've been using Protein World's Slender Blend for a while now and have grown to love the shakes. Alongside my busy lifestyle and my training regime the shakes help me build strength and maintain a balanced diet. Training can be hard sometimes... You have to remember to set realistic goals. Things that you will actually hit and start slowly. But reward yourself when you hit that goal… then set a new goal'.
