Top 23 Fitness Influencers to Inspire You to Get into Shape this Summer

For the last decade, there has been a gradual explosion of influencers on social media, people who inspire millions of people each day. These influencers have made posts covering a wide variety of genres, but fitness is one niche that has remained popular from the beginning. We react well to seeing fit, healthy influencers showing us how they look due to their exercise and fitness routines. Indeed, good fitness influencers can inspire even the most lethargic couch potatoes to exercise and try and emulate their healthiness, at least for a short time.

Of course, many of the fitness influencers we spend time admiring on Instagram have busy lives outside the gym. The most popular fitness influencer, The Rock, is probably better known nowadays for his film career than the activities he initially engaged in that gave him his name. Yet, when you look at the Instagram images he shares, it's evident that fitness is still vital to him today.

It didn't take brands long to recognize the potential for working with fitness influencers (albeit the fitness superstars are out of the league financially for all except the most prominent brands.) Many now leverage fitness influencers to help with their marketing campaigns. In this post, we look at some of the most influential people on Instagram who regularly make posts relating to fitness.
