How AI is transforming the fitness industry

Before digging into a long-awaited meal, you may wonder about the true nutritional value of your food. Now, by simply snapping a picture of the burrito bowl sitting in front of you, detailed statistics about the nutritional contents of your meal are generated within seconds. As the modern world of sports becomes increasingly attentive to the impact of diet and macronutrient intake on fitness and athletic performance, new innovations are accommodating to this focus. This is mainly made possible by one thing: artificial intelligence.

Like many other facets of our day-to-day life, AI has become one of the most convenient and accessible tools in the fitness industry. Beyond ChatGPT and other large language models, AI has been integrated into programs such as Whoop, Peloton, and other fitness-related tools and appliances. The rise of machine learning in the fitness industry mirrors its success in other fields; its efficiency and personalized nature cut the time it takes to manually research fitness goals to just a few seconds.

Some AI fitness scanners, like Fitbod, are able to assess the client’s physical state (age, weight, medical condition, BMI) in more detail than a personal trainer would be able to achieve. Apps then take that information to tailor a specific workout regimen — all in a matter of minutes. Rather than investing hundreds of dollars into a trainer, AI offers a cheap, innovative alternative.

“When I didn't know how to work out and it was difficult for me to find resources which were beginner friendly, AI was the way to go,” said Aarav Upadhyay ’27.

Not only can AI be used to gather data on the athlete’s physical metrics, it’s used as a tool to predict injuries and outcomes. Wearable bracelets are able to sense muscle imbalances and stress patterns before it’s too late. The Dallas Cowboys implemented this wearable tech system for performance analysis and injury prevention, an issue that has long plagued the sport. Additionally, Paralympic cyclist Skylar Espinoza praised AI fitness program Parity in helping her track her biometrics ahead of the Olympic Games.

Despite the benefits and streamlined efficiency, there are concerns over AI’s privacy and reliability. These fitness trackers collect massive amounts of data on a person with little to no guarantee of misuse or breach. Systems with a poorly trained algorithm are capable of recommending risky or even dangerous workouts, increasing the risk of injury. In sports, AI implementation has caused arguments on who has the final say in injury situations: the coach, athlete, or AI.

“I don’t use AI trackers for my sport because the US figure skating [team] has their own app,” said Audrey Chiu ’26. “I don’t actually trust it because it can’t really know what’s going on in human bodies.”

While it is tempting to immediately turn to AI for advice, PHS students have many resources at their disposal, ranging from health classes and gym teachers to professional guest speakers who teach us about fitness and nutrition. An overreliance on technology is dangerous, especially if we entrust our physical health with it: AI indiscriminately sources from the internet, and it is our job to be proactive by verifying generated answers.
