As one patron at the gym put it "It's very good motivation,' Ms. Wong said, pointing at the fluorescent bulb above her head. 'You can watch yourself burning fat to turn on that light."' Although the power generated at the [gym only totaled to 300 watts](https://www.trendhunter.com/trends/revolutionary-fitness-experience) when the "13 machines, it was enough energy to "run three 27-inch television sets, five 60-watt light bulbs or several hundred video iPods. If all the [exercise machines](https://www.trendhunter.com/trends/connected-gym-ecosystem) were in use 10 hours a day for a year, the gym could generate roughly $183 worth of electricity. It doesn't seem like much but if all the gyms in this country did this..."well,you do the math." ## Trend Insights (Trend Hunter) - Score: 3.9/10 - Popularity: 30% | Activity: 80% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: South America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Key Themes Behind This Trend - **Green Gyms:** The trend towards 'green gyms' utilizing human-powered energy could be capitalized on by innovative gym equipment manufacturers. - **Energy-monitoring Apps:** The increasing use of energy-monitoring apps could be utilized to incentivize gym-goers to work harder and generate more energy. - **Community Energy Sharing:** The development of community energy sharing models could allow gyms to sell excess energy generated to nearby businesses or residents. ### Where This Applies - **Fitness Equipment Manufacturing:** Companies that produce gym equipment have the potential to innovate by producing machines that harness human-power and act as generators, therefore providing 'green energy' that gyms could use or sell to other businesses. - **Mobile Health Technology:** Mobile health technology companies could develop tracking apps that monitor energy output for gym-goers to make energy output tangible and may provide incentive for people to work out harder and burn more calories for energy - **Energy Trading:** Companies with experience in energy trading could develop models and technologies to allow sharing the excess energy generated by gyms in their community, making for a more sustainable business model and positive impact on the environment and economy. ## Related on Trend Hunter - [Power-Generating Desk Bikes](https://www.trendhunter.com/trends/lifespan-ampera.md) - [Productivity-Supporting Exercise Bikes](https://www.trendhunter.com/trends/acer-ekinekt-bd-3.md) - [Regenerative Cycling Equipment](https://www.trendhunter.com/trends/energy-keeper.md) - [Collaborative Sports Performance Centers](https://www.trendhunter.com/trends/everlast-gyms.md) - [Fitness-Focused Electric Motorbikes](https://www.trendhunter.com/trends/gymofit-motorbike-concept.md) - [Modular Smart Gyms](https://www.trendhunter.com/trends/fittransformer.md) - [Plug-and-Play Workout Equipment](https://www.trendhunter.com/trends/pocket-gym.md) - [In-Gym Hotels](https://www.trendhunter.com/trends/in-gym-hotel.md) - [Modular Exercise Machines](https://www.trendhunter.com/trends/modular-home-gym.md)
