I like working. 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 actually detest energy coaching.
Sadly for me, it’s extraordinarily good for you—and for runners who wish to get quicker. So I made a decision so as to add in two strength-training periods per week in preparation for working the Boston Marathon this spring.
I needed workouts designed to enhance my tempo, however didn’t wish to spend cash on a private coach. Uncertain of begin, I turned to ChatGPT.
The chatbot didn’t give me the exercise routine I hoped for—and after following its suggestions for almost a month, I used to be no nearer to liking energy coaching. However I realized some issues alongside the best way which may find yourself serving to me grow to be 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 might 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 working coach who’s completed greater than a dozen marathons, I’ve an excellent sense of what a stable coaching schedule seems like. The ChatGPT outcomes had been—not that. Though it informed me to run about six days every week at varied speeds and distances (thus far, 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, apart from the suggestion to run a full marathon every week earlier than the tip—one thing no authentic 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 objectives. Now, it solely informed me to run as much as 12 miles. As compared, the longest run on most respectable marathon plans is eighteen to 22 miles.
Learn Extra: Your Mind Does not Need You to Train
It’s not arduous to discover a first rate coaching plan on-line. So though I didn’t anticipate ChatGPT to invent a mindblowing routine, I used to be stunned that the plans it spat out had been so underwhelming and at instances incomprehensible. However perhaps I shouldn’t have been. What ChatGPT does so effectively is generate “a human-like, pure language output,” explains Richard Bayly, vp 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 prefer it is aware of what it’s speaking about, it doesn’t.
ChatGPT’s major talent lies in sounding human, not in giving professional suggestions. The web site even embrace a disclaimer to “verify your info,” stating that the chatbot shouldn’t be supposed to present recommendation. Even so, individuals are already utilizing the location for exercise strategies. (OpenAI didn’t reply to a request for remark for this piece.)
Lesson 2: ChatGPT generated first rate train concepts
Though it failed my marathon plan litmus take a look at, I nonetheless needed to see if ChatGPT may give me some concepts for energy coaching. After asking “which physique weight–solely energy coaching workouts will assist me run quicker,” it listed 12 workouts that appeared pretty stable, hitting virtually all the key muscle teams utilized in working. However as I began to do the exercise, I spotted I didn’t have any info on units, reps, or whether or not I ought to do every train separately versus in a circuit.
I’m not the one one who has found ChatGPT’s exercises are lacking basic particulars. One January 2024 examine evaluating ChatGPT-generated exercises discovered its train suggestions had been solely 41% complete—which means its solutions didn’t embrace the entire American Faculty of Sports activities Medication’s six elements of train 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 folks to get medical clearance to train after they didn’t want it. That 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 folks from exercising altogether. “Requiring somebody to get medical clearance is a serious deterrent to enterprise an train program,” she says.
Performed proper, AI has actual potential to get extra of us shifting. In a latest report funded by the sportswear firm ASICS, 62% of ladies named the excessive price of trainers as a serious 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 be taught extra, so I stored questioning the efficacy of the workouts.
Additionally, the exercise was boring, made up of fundamental American gym-class workouts that felt cookie-cutter, regardless of all the private information I’d included in my prompts.
“There’s the science of train prescription, and there is the artwork,” says Pescatello. A robotic may 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 with no 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—when you had been additionally a machine.”
Lesson 4: Flip to a human when 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 prompt I persist with low-impact actions like strolling if the “ache is delicate and bettering.”
I introduced this up with New York-based adidas working coach Jessica Zapotechne. Was this sound or overly conservative recommendation? “That query makes me take into consideration a subject that I discuss with athletes about so much, which is distinguishing between ache and discomfort,” she tells me. There are various kinds of hurting, and figuring out what is solely a part of coaching versus indicators of an harm requires “a listing of inquiries to undergo,” she says. That’s one other drawback with AI coaches: They don’t ask questions, the best way a human coach sometimes would.

“You have to be very cautious about your inputs, as a result of when you have unhealthy inputs, you are going to have unhealthy outputs,” says Bayly of PEAR Well being Labs. “A generative AI chatbot is relying largely on info that is extensively accessible. I do not assume 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 in case you are not particular sufficient.” AI-based exercise apps like Aaptiv have customers reply a number of questions on their objectives, expertise, age, and extra upfront as a way to generate personalised suggestions, that are then refined additional by monitoring what the consumer does on the app, à la Netflix.
The difficulty is, somebody who’s trying to AI for train concepts in all probability doesn’t know precisely what particulars they’d have to share to get essentially the most useful reply.
“The one who has the talent to write down an incredible command in all probability has sufficient talent to simply write the exercise,” says Chicago-based energy coach Elisabeth Akinwale. Alternatively, she provides, if somebody is asking ChatGPT for exercise assist, they may not have the data to appreciate 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 an incredible search device. With cautious prompting, you might 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 trying to combine issues up with a brand new concept so as to add to their rotation.
Nonetheless, you’d have to suit inside a slim inhabitants to get one of the best outcomes. Pescatello says her workforce discovered that ChatGPT’s suggestions are at the moment biased towards adults and lack cultural consciousness or concerns for disabilities. Their evaluation additionally scored the readability on the school degree.

Regardless of ChatGPT not turning out to be the free private coach I needed, I’m nonetheless doing a few of its advisable strength-training workouts usually. I haven’t gotten quicker but, although we’ll see what occurs on marathon day.
I discover I preserve going again to ask ChatGPT my 3 a.m. exercise questions that really feel too foolish or inconsequential to hassle one other human with. It’s confirmed most helpful after a session speaking to a sports activities dietitian, once I wanted a easy rationalization of “anabolic potential.” The primary few outcomes Google introduced up had been too sciencey, however once I requested ChatGPT to outline it for an eighth grader, I acquired precisely what I used to be on the lookout for: “the physique’s capability to construct and restore tissue, particularly muscle tissues.” 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.
