Social media is full of influencers who produce content from a number of genres such as beauty, lifestyle and travel. Health and fitness influencers are some of the most inspirational influencers on social media channels, especially Instagram, with a base of loyal followers. The top fitness influencers on Instagram dominate the platform by showcasing their discipline and dedication not only to themselves, but to their fans. Fitness influencers are motivated to improve the lifestyles of their followers in ways that are fun and engaging. From releasing exciting recipes and nutrition plans to uploading short workout videos, health and fitness bloggers have a positive influence on millions of Instagram users. 

It may be intimidating scrolling through health and fitness influencers’ Instagram profiles as they show off their lean muscles and sculpted abs. However, what makes these Instagram influencers so inspiring is that they don’t expect their followers to train like crazy to achieve their body goals. Instead, health and fitness influencers recognise that there is no such thing as an ideal body type, and they reject society’s notion of what bodies should look like. Many fitness influencers prioritise adopting a healthy mindset which leads to a healthier lifestyle. For example, many influencers have been open with their supporters about their own fitness journeys, with many having transformed their out of shape bodies into bulging muscles. As a result, these influencers demonstrate that whilst beginning a fitness journey is difficult, it is not impossible. 

Many brands choose to collaborate with health and fitness influencers due to their large reach as well as their optimistic approach to healthy eating and exercise. From creating activewear to being the face of a new protein shake, there are endless possibilities for brands to benefit from fitness influencers. 

We have created a list of the most famous fitness influencers on Instagram who are changing people’s lives for the better.
