In a game like Gym League, the best way to train with your friends or even do a custom bodybuilding competition in Roblox is to use a private server. So, if you’re looking for some private servers to access in-game, I highly suggest browsing the article below where I’ve provided free links to two of them!

If you are a mobile or computer user, open the given web page on one of your browsers, such as Chrome or Mozilla Firefox, and click one of the links to access the servers directly. For console users, ask one of your friends from the above mentioned platform to join first and then send you a friend request.
