The Rise of Fitness Influencers on Other Platforms

Instagram was the platform where fitness influencers became major social media personalities with huge audiences. Now, however, fitness influencers are also gaining popularity on other platforms. In particular, many fitness influencers have been posting on TikTok, either exclusively or in addition to posting on other platforms. The top male fitness influencers on TikTok, for example, are not all the same as the top male fitness influencers on Instagram. 

Some creators recognize the value of developing a cross-platform audience and post content on several social media platforms. They can create short-form videos for TikTok and then repurpose that content and post it on Instagram Reels or even in their feed. It’s fairly easy to rework the same content slightly so it’s ready for other platforms. This way, the fitness influencers are able to take advantage of the audiences primarily consuming content on TikTok, Facebook, or any other social media site. Learn more about how to use influencer search tools for finding the best fitness influencers of 2024.
