The Olympic gold medallist (pictured) began his pro career with a first round win over Emanuele Leo at London’s O2 Arena last Saturday (Oct 5).
Joshua will train using a range of LA Muscle supplements and protein following a nutrition plan put together by the brand and its team of nutritionists.
The 23-year-old says: “Having LA Muscle in my corner was a real boost ahead of my professional debut.
“It’s important for me to have the right nutrition in place to help me achieve my goal of being the best I can be.
“I’m looking forward to working with the team following a positive start at the O2 on Saturday night.”
