THE TOP 10 FITNESS HASHTAGS FOR TIKTOK FOR 2025

Before you start using some of the top 10 most popular fitness hashtags on TikTok in 2025, let me tell you something you probably have been turning a blind eye to…

TikTok is not helping your business

• TikTok is a “money extraction” machine. Its business model is designed to make money from you. Its algorithm has been deliberately engineered to lower your organic reach so you have to buy ads to reach your followers.
• That’s why a tiny fraction of your followers get to watch your videos on TikTok. A massive issue affecting thousands of marketers. 
• You keep trying to build an audience on TikTok you will never own. 
• You cannot transfer your hard-earned TikTok followers to your best CRM software.
• Your customer acquisition costs from TikTok ads are through the roof.

The solution

I can offer you the best digital marketing strategy workshops that will help you:

• Lower customer acquisition costs.
• Minimise dependency on paid media.
• Build a marketing engine with marketing assets and channels you fully own.
• Craft the best digital marketing plan and social media strategy that boosts sales and customer lifetime value.

What are the most popular fitness hashtags on TikTok in 2025?

I am surprised many gym owners and fitness trainers are not using some of the most popular TikTok fitness hashtags to amplify and reach more followers and new potential customers.

We have completed this research so you can start using some of the top 10 most popular fitness hashtags for TikTok listed below…

Customer segmentation – An important step for fitness content success

Before you start using some of the below most popular fitness hashtags on TikTok, you may want to also use some niche, unique fitness hashtags that will connect you to your exact audience.

For example, if you provide fitness services for rock climbers in New York, you may also want to use “rock climb” “NYC” related hashtags.

Publishing popular fitness hashtags will surely bring you likes to your TikTok content, it may not be enough to reach your desired audience.

If you want to have – let’s say – 30 great exclusive clients per week, then you do not necessarily need thousands of “likes” and “followers” on TikTok.

You may decide to reach – let’s say – mums with babies between 30-40 years old who are looking for belly blaster workouts in San Francisco’s Haight Ashbury area. That’s quite a niche and that could be enough business for you. Then you will use far better hashtags as you know the exact people you want to reach.
