I like operating. I’ll fortunately jog for hours (and infrequently do, throughout marathons). However ask me to carry out a push-up, and I would cry. I really detest power coaching.
Sadly for me, it’s extraordinarily good for you—and for runners who want to get faster. So I made a decision so as to add in two strength-training classes per week in preparation for operating the Boston Marathon this spring.
I wished workouts designed to enhance my tempo, however didn’t wish to spend cash on a private coach. Uncertain of tips on how to begin, I turned to ChatGPT.
The chatbot didn’t give me the exercise routine I hoped for—and after following its suggestions for practically a month, I used to be no nearer to liking power coaching. However I discovered some issues alongside the best way that may find yourself serving to me develop into a greater runner.
Lesson 1: ChatGPT shouldn’t be a lot of a coach
OpenAI’s free AI chatbot is educated on huge quantities of information from sources across the Web so it will probably reply prompts with human-like textual content. To check out its exercise suggestions, I first requested it to create a marathon coaching plan.
As a operating coach who’s completed greater than a dozen marathons, I’ve a superb sense of what a strong coaching schedule seems like. The ChatGPT outcomes had been—not that. Though it instructed me to run about six days every week at varied speeds and distances (up to now, so good), it listed hill sprints and intervals with out important particulars like how briskly or far. It additionally gave me no runs longer than 14 miles, except for the suggestion to run a full marathon every week earlier than the top—one thing no legit coach would ever advise, since that’s far too taxing on the physique to be useful, particularly so near race day. I requested the query twice extra, including particulars about my health degree and targets. Now, it solely instructed me to run as much as 12 miles. As compared, the longest run on most respectable marathon plans is eighteen to 22 miles.

It’s not arduous to discover a respectable coaching plan on-line. So though I didn’t count on ChatGPT to invent a mindblowing routine, I used to be shocked that the plans it spat out had been so underwhelming and at instances incomprehensible. However possibly I shouldn’t have been. What ChatGPT does so nicely is generate “a human-like, pure language output,” explains Richard Bayly, vice chairman of product, AI, and information at PEAR Well being Labs, which owns the AI-powered health app Aaptiv. However whereas the chatbot is designed to sound like it knows what it’s talking about, it doesn’t.
ChatGPT’s major talent lies in sounding human, not in giving skilled suggestions. The web site even embrace a disclaimer to “verify your information,” stating that the chatbot shouldn’t be meant to offer recommendation. Even so, persons are already using the site for workout suggestions. (OpenAI didn’t reply to a request for remark for this piece.)
Lesson 2: ChatGPT generated respectable train concepts
Though it failed my marathon plan litmus take a look at, I nonetheless wished to see if ChatGPT may give me some concepts for power coaching. After asking “which physique weight–solely power coaching workouts will assist me run sooner,” it listed 12 workouts that appeared pretty strong, hitting nearly all the foremost muscle teams utilized in operating. However as I began to do the exercise, I noticed I didn’t have any info on units, reps, or whether or not I ought to do every train one after the other versus in a circuit.
I’m not the one one who has found ChatGPT’s exercises are lacking elementary particulars. One January 2024 study evaluating ChatGPT-generated exercises discovered its train suggestions had been solely 41% complete—that means its solutions didn’t embrace the entire American Faculty of Sports activities Drugs’s six parts of exercise prescription: frequency, depth, time, sort, quantity, and development.

But the researchers did discover the exercises to be 90% correct. Many of the inaccuracies concerned telling individuals to get medical clearance to train after they didn’t want it. Which may appear innocuous, however Linda Pescatello, a professor within the division of kinesiology on the College of Connecticut and one of many examine’s authors, says this might discourage individuals from exercising altogether. “Requiring somebody to get medical clearance is a significant deterrent to enterprise an train program,” she says.
Finished proper, AI has actual potential to get extra of us transferring. In a recent report funded by the sportswear firm ASICS, 62% of girls named the excessive value of trainers as a significant barrier to exercising. A free, simply accessible chatbot providing focused, on-demand exercise recommendation on a mass scale could possibly be a boon to public well being.
Lesson 3: The chatbot’s exercises are boring and uninspired
Two weeks into my strength-training plan, I discovered myself skipping sure strikes and swapping in others as an alternative. The issue was, I didn’t belief Coach ChatGPT. Did I really want to do burpees, or had the chatbot merely come throughout them in some random “exercise for runners” article? The solutions hadn’t given me any info on why I used to be doing the strikes, or hyperlinks to study extra, so I saved questioning the efficacy of the workouts.
Additionally, the exercise was boring, made up of primary American gym-class workouts that felt cookie-cutter, regardless of all the non-public information I’d included in my prompts.
“There’s the science of train prescription, and there is the artwork,” says Pescatello. A robotic might need accomplished my prescribed exercise and gotten outcomes, however I’m far too human to pump out the identical 12 bland strikes with gusto—particularly and not using a coach to carry me to it. “It would not account for humanity in any respect,” says Kristie Larson, a New York–based mostly private coach. “Positive, it’d write an excellent coaching plan—in the event you had been additionally a machine.”
Lesson 4: Flip to a human in the event you get injured
At one level, my sartorius muscle in my thigh began to behave up. I requested ChatGPT, “Can I nonetheless run if my sartorius muscle hurts?” It gave me a obscure, long-winded reply that wasn’t precisely “no,” however instructed I keep on with low-impact actions like strolling if the “ache is gentle and bettering.”
I introduced this up with New York-based adidas operating coach Jessica Zapotechne. Was this sound or overly conservative recommendation? “That query makes me take into consideration a subject that I speak with athletes about loads, which is distinguishing between ache and discomfort,” she tells me. There are several types of hurting, and figuring out what is just a part of coaching versus indicators of an damage requires “a listing of inquiries to undergo,” she says. That’s one other downside with AI coaches: They don’t ask questions, the best way a human coach usually would.

“You have to be very cautious about your inputs, as a result of in case you have dangerous inputs, you are going to have dangerous outputs,” says Bayly of PEAR Well being Labs. “A generative AI chatbot is relying largely on info that is extensively obtainable. I do not suppose there’d be loads of distinction between a generic program that you simply may be capable of obtain off the Web versus one thing the chatbot may return if you’re not particular sufficient.” AI-based exercise apps like Aaptiv have customers reply a number of questions on their targets, expertise, age, and extra upfront with the intention to generate customized suggestions, that are then refined additional by monitoring what the person does on the app, à la Netflix.
The difficulty is, somebody who’s seeking to AI for train concepts in all probability doesn’t know precisely what particulars they’d have to share to get probably the most useful reply.
“The one that has the talent to write down a fantastic command in all probability has sufficient talent to only write the exercise,” says Chicago-based power coach Elisabeth Akinwale. Alternatively, she provides, if somebody is asking ChatGPT for exercise assist, they won’t have the information to understand when it spits out one thing wacky, like my marathon coaching plans. “They do not have the discernment to say, no, that does not sound correct,” she says.
So what’s ChatGPT good for, on this planet of health?
In a phrase: “Selection,” says Pescatello. “One of many capabilities AI has in any career is it may be a fantastic search device. With cautious prompting, you possibly can specify your preferences and an output could possibly be generated that offers you extra choices than you are feeling there are actually.” Larson echoes that sentiment, saying it could be finest utilized by somebody skilled who’s simply seeking to combine issues up with a brand new concept so as to add to their rotation.
Nonetheless, you’d have to suit inside a slender inhabitants to get the most effective outcomes. Pescatello says her workforce discovered that ChatGPT’s suggestions are presently biased towards adults and lack cultural consciousness or concerns for disabilities. Their evaluation additionally scored the readability on the faculty degree.

Regardless of ChatGPT not turning out to be the free private coach I wished, I’m nonetheless doing a few of its really useful strength-training workouts repeatedly. I haven’t gotten sooner but, although we’ll see what occurs on marathon day.
I discover I hold going again to ask ChatGPT my 3 a.m. exercise questions that really feel too foolish or inconsequential to trouble one other human with. It’s confirmed most helpful after a session speaking to a sports activities dietitian, after I wanted a easy clarification of “anabolic potential.” The primary few outcomes Google introduced up had been too sciencey, however after I requested ChatGPT to outline it for an eighth grader, I bought precisely what I used to be searching for: “the physique’s capability to construct and restore tissue, particularly muscle groups.” I’m lastly utilizing it for what it’s designed to do: to not give train recommendation, however to generate natural-sounding, easy-to-understand language.
