ChatGPT can plan your workouts, but it doesn’t know the human body


When I opened the email indicating that I accepted to play the London Marathon (UK), I was elated. But then I was horrified. Barely six months after my last marathon, I knew how committed he was to training day after day, week after week, month after month, against rain, cold, exhaustion, bad moods, and a hangover.

What no one is warning us about is that the marathon is the easy part. The constant grind of training is what kills us, and finding ways to keep that training fresh and fun is part of the challenge.

Some exercise enthusiasts think they’ve found a way to do just that: use ChatGPT, and Chat bot Artificial intelligence (AI), as a kind of personal trainer. Created by OpenAI, this model can produce anything from love poems to legal documents, and athletes are using it to make routine running more fun. Some entrepreneurs prepare business plans fitness of ChatGPT and sold.

Its attractiveness is clear. ChatGPT answers questions in seconds, saving you the need to filter through tons of information. In addition, the user can ask follow-up questions to get a more detailed and personal answer. ChatGPT’s tone of mouth is ideal for giving advice fitness, And the information is clear. Open AI He’s pretty blunt about the details, but we know that ChatGPT was trained on data pulled from search engines, Wikipedia entries, and archived books, so it might seem apt to answer general questions. Although there is no guarantee that these answers are correct.

So is ChatGPT the future of how are we going to train? Or is he just a trusted liar?

Auto drills

To test GPT’s ability to create programs fitnessI asked him to write me a plan for a marathon 16 weeks. It soon became clear that this wouldn’t work. Proper training for a marathon should gradually increase the distances covered each week. The common belief is that the longest distance should be about 20 miles (32 km). ChatGPT suggested max 10 miles (16 kilometers). I shudder to imagine how I would be able to run a marathon with so little preparation, I would be in so much pain and at risk of injury.

When I asked him the same thing again in another conversation: “Write me a 16-week training plan for a marathon,” he suggested running 19 miles (30 kilometers) the day before the race. Again, that would be a recipe for disaster. I would have exhausted myself at the marathon starting line, or because of an injury.

I wasn’t sure why ChatGPT would give me two different answers to the same question, so I asked OpenAI. Their spokesperson told me that large language paradigms tend to generate a different answer to a question each time it’s asked, adding, “It’s because it’s not Database. Generates a new answer with every question or query. The Open AI website also states that while ChatGPT can learn from questions and answers within a conversation, it cannot use past conversations to elicit future answers.

An OpenAI spokesperson asked why ChatGPT gave me potentially harmful advice, and he replied: “It is important to remind readers that ChatGPT is in beta for research purposes, and we inform you that it may produce incorrect information and result in Harmful instructions or biased content“.

One of my AI-generated plans offers a warning that it’s a good idea to consult a trainer. Another advised me to listen to my body and take rest days. Others do not contain any warning. answers Chat bot They are inconsistent and unhelpful.

In the end, I was disappointed and a little anxious. It didn’t work for me. However, while searching for Tik Tok, Reddit, and Twitter, I found that many people have used ChatGPT to create training plans. And some, other than me, followed his suggestions.

ChatGPT limits test

ChatGPT training tips can be, to say the least, impressive. Austin Goodwina fan of fitness And a resident of Tennessee (USA), he discovered that he works as a content creator and started playing around with general questions about the workout.

Goodwin asked the model about progressive overload when lifting weights (gradually increasing the weight lifted, or the number of repetitions), and why Calorie deficit to lose weight. “It gave answers you’d expect from someone with several years of knowledge. It’s like putting steroids on Google search or Wikipedia: It amplifies it, takes it to the next level,” he says.

Goodwin isn’t the only one who sees ChatGPT as a potential competitor to Google Search: Google management has declared it a threat in the red.

I found ChatGPT to be good at finding information when I asked it to write a weightlifting plan (for theoretical purposes only, I had no intention of lifting any irons according to the AI’s advice). He responded with an acceptable routine of exercises such as squats, push-ups, and lunges. To test its limits, I also told the model that my goal was slim down (Again, I lied, for the noble purposes of journalism.) He gave me a cautious response, advising me that “in order to lose weight, it’s important to pay attention to your diet.” Now, very true.

Goodwin tested the limits of ChatGPT by asking questions he already knew the answers to. I did that too Alex CohenAnother fan of fitnesswho works for Carbon Health .start from medical care.

Cohen started by asking you to calculate your daily energy expenditure (the total number of calories a person burns in a day), which is a useful tool for estimating how much you need to consume to lose, maintain or gain weight. Then he asked her to make eating and exercise plans. Like Goodwin, he was impressed with the way this model presented information. However, it has been made clear that it will not replace a nutritionist or a health professional personal trainer.

“He doesn’t customize workouts based on my body shape, build, or experience,” says Cohen. ChatGPT does not ask users additional questions to improve their answers.

in the gym

Despite the variable quality of advice fitness From ChatGPT, some people have implemented their recommendations at the gym.

US-based TikTok content creator John Yu signed himself up after a full six-day training program recommended by ChatGPT. Yu asked him for a training plan for each day, adapted to the part of his body he wanted to work on (arms, legs, etc.), and then performed the suggested training.

The recommended exercises were adequate and easy to follow. However, Yu found that they lacked variety. “I’m not interested in strictly following what ChatGPT has to offer,” Yu admits.

Bodybuilding content creator Lee Lim (Australia), had a similar experience. ChatGPT was asked to create the “perfect leg workout” schedule. The model suggested the correct types of exercises (squats, lunges, deadlifts, etc.), but rest times Between them they were too short. “It’s hard! It’s unrealistic to rest only 30 seconds between those sets of squats,” Lim admits, laughing.

Lem identified the problem with ChatGPT suggestions: they don’t take human bodies into account. He and Yu found that the repetitive motions hurt or tired her. Human trainers know how to combine their suggestions, while ChatGPT has to receive this pointer explicitly.

However, for other people, the temptation to exercise generated by AI is irresistible, and they are willing to pay for it. Ahmed Mir – Engineer at software In london sell plans created by chatgpt for $15 (13.8 euros) each. Clients give him their training goals and specifications, and he manages them through ChatGPT. Mayer confirms that he has already had many clients since he launched the service in December 2022, and he is also considering adding another option to create diets. ChatGPT is free, but people pay for the convenience.

Everyone I spoke to was united in their decision to treat ChatGPT training suggestions as fun experiments, not a training guide to take seriously. Everyone has knowledge fitnessThey know what works and what doesn’t for their bodies, and so they find out Weak form. They were all known to treat their answers with skepticism. However, exercise beginners can take it literally.

What is the future fitness?

This is not to say that AI models cannot or should not play a role in developing plans. fitness. Although, oddly enough, they can not always be trusted. ChatGPT will get better, and you can learn to ask your own questions. For example, you can ask users if there are any exercises they hate, or ask them about them Injuries and discomfort. But the AI ​​model cannot make original suggestions and has no basic understanding of the concepts it emits.

Because it’s been trained on the web, what it suggests may be something you don’t know about but others will, says Philip de Wilde, a professor of artificial intelligence at the University of Kent in England. Although many of his responses are technically correct, a human expert will always be better.

If this helps, ChatGPT can be attempted to liven up an exercise program that is out of date, or as a way to save time by suggesting exercises you may not have thought of. “It’s a tool, but it’s not gospel,” says Rebecca Robinson, MD, a consultant in sports and exercise medicine (UK).

Off the internet, I ended up taking advice from books and magazines written by experts to design my own marathon training plan, which looks pretty good to me after four weeks.

However, I am not the only one Which rejects ChatGPT hints: Lem only followed your suggestions for the purpose of recording a video; Whereas Yu went back to his old workout routine without the use of AI, which is what he enjoys the most, he told me. “I’d rather keep doing it and tweak it than feed ChatGPT more info and still be unhappy.”
