Increasing the number of codes on the schedule to more than 50 at this year's multi-sport festival, the event is set to take place at the Sandton Convention Centre and will hold another health and fitness expo, which last year hosted 200 exhibitors.
The 2017 Arnold Classic Africa will be held in partnership with the Gauteng provincial government and the SA Sports Confederation and Olympic Committee (SASCOC).
Wayne Price, Arnold Classic Africa partner said: "Last year we were really pleased with the response and the turnout, and this year we want to make sure every visitor to our event has more to do and more to see.
"After attracting world-renowned stars to compete in 2016, we are aiming to do the same once again, and the additional sports are expected to attract more athletes and spectators. With just 100 days to go, the excitement is building fast and we are eager to host another spectacular showpiece."
Faith Mazibuko, the Gauteng MEC for Sports, Arts and Culture said: "We are pleased to once again play a role in such a popular event, which helps us to meet our objectives in bringing people together and promoting health and fitness.
"After seeing the success the Arnold Classic Africa enjoyed last year, we are confident it will once again be enjoyed by thousands of people in our province, across the country and around the world."
