After a festive period filled with indulgent treats and downtime, numerous individuals head into January looking to get their fitness back on track.

But, could Artificial Intelligence be transforming the fitness industry by providing an option to human coaches?

Tailored Plans and Adaptable Timelines

One fitness enthusiast employed an artificial intelligence application for last-minute preparation for the a major running event.

The 21-year-old hailing from Aberdare explained she liked the liberty to ask it questions at all hours – a feature she felt was unavailable with a personal trainer.

Leah used an AI-driven running app that provided her personalised plans with audio coaching and pace setting for her first half marathon in 2024.

She said she asked it to create a plan merging running and the gym, and it generated an 11-week programme tailored to her event day and objectives.

Leah then adjusted the plan to fit her daily routine, which she described was convenient.

Subsequently, she opted for a alternative application because it was more affordable and she could consult it at any time. She finished a minute faster than her goal time.

She noted she wanted to avoid the pressure from a live instructor.

"With artificial intelligence you have to motivate yourself, which I quite like," she added.

Remarkable Strength Improvements

Meanwhile, Richard Gallimore, in his twenties, based in a Welsh city, has been using artificial intelligence for his exercise and nutrition programs, and reported he has achieved peak strength, boosting his chest press from a lower weight to a much heavier load.

Richard resorted to a bot for help after being forced to walk a race.

"I realized I need to get myself in shape," he said.

The free tool built a workout and diet plan personalized to his goals, and established structured routines.

"I train for about two hours a day and I've seen a noticeable change," he said.

The Cost Comparison: Technology vs. Traditional Training

One recent study in late 2024 analyzed prices for 17 of the largest gym brands and found the average membership cost was around £38 a month, based on basic full-access plans.

Prices ranged from £23 at the most affordable chain to £132 at the highest-priced.

According to industry research, personal trainers determine their own fees, typically £30-£65 per hour-long appointment outside London and about £45-£65 in the capital.

Clients typically hire a coach one or two times a week and work with them for a few months, however these arrangements are often adaptable.

The Essential Human Touch

Fitness coach one experienced professional, from the Welsh capital, acknowledged AI can be beneficial to accelerate results, but is convinced it will never replace the personal interaction and accountability that live training provides.

The 37-year-old, who has over a decade of experience as a coach, specialises in older adults and injury rehabilitation. He said a number of his trainees also employ technology.

"In my opinion it's extremely useful, more knowledge is good," he stated.
"I think the more that people are connected digitally the more they'll want human connection because they want the warmth from the comprehension that is absent from a machine," he continued.

Dafydd explained AI can inform clients and make guidance more effective.

But, he argued real commitment comes when people appear in person for training.

"As useful as it is at 2am, a digital tool cannot ensure you show up at early morning before work," Dafydd added.

For many, he suggested, the fitness center is a space to disconnect from devices and take a break from technology.
