After a holiday period filled with indulgent treats and downtime, many people head into the new year aiming to get their fitness back on track.

But, could Artificial Intelligence be changing the world of exercise by offering an option to personal trainers?

Personalized Plans and Adaptable Timelines

Leah Walsh used an AI tool for impromptu preparation for the Cardiff Half Marathon.

This young woman hailing from Aberdare said she liked the liberty to pose queries any time of day – a feature she believed was not possible with a traditional coach.

Leah relied on an AI-driven running app that provided her customized schedules with audio coaching and speed targets for her inaugural long-distance race in 2024.

She said she requested it to create a regimen combining running and the gym, and it produced an multi-week programme customized to her race date and goals.

Leah then adjusted the plan to suit her daily routine, which she said was highly practical.

Subsequently, she opted for a different tool because it was cheaper and she could consult it at any time. She finished a minute faster than her target finish.

She said she wanted to avoid the pressure from a human personal trainer.

"With AI you have to find your own drive, which I quite like," she remarked.

Significant Strength Improvements

Meanwhile, Richard Gallimore, 23, based in Swansea, has been employing artificial intelligence for his exercise and nutrition programs, and reported he has never felt stronger, increasing his chest press from a lower weight to 110kg.

Richard turned to a AI assistant for help after being forced to walk a race.

"I just knew I need to sort myself out," he said.

This no-cost application constructed a fitness and meal program tailored to his goals, and created structured routines.

"I train for about 120 minutes a day and I've seen a noticeable change," he added.

The Cost Comparison: Technology vs. Traditional Coaching

One recent survey in late 2024 analyzed costs for numerous of the biggest fitness chains and found the average membership cost was around £38 a month, for standard full-access plans.

Fees started at £23 at the most affordable provider to £132 at the highest-priced.

According to industry research, personal trainers set their own rates, typically £30-£65 per hour-long appointment in most areas and about a similar range in the capital.

Clients will often hire a trainer once or twice a week and work with them for a few months, but these agreements are often adaptable.

The Essential Human Element

Personal trainer Dafydd Judd, based in the Welsh capital, acknowledged AI can be beneficial to speed up progress, but believes it will never replace the personal interaction and accountability that live training provides.

This expert, who has over a decade of experience as a trainer, specialises in older adults and recovery from injuries. He said a number of his trainees also employ AI.

"I think it's extremely useful, additional information is positive," he said.

"I believe the more that people are connected digitally the more they'll want human connection because they want the warmth from the understanding that is absent from a machine," he added.

Dafydd explained Artificial intelligence can educate users and make guidance more effective.

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

"As useful as it is at the middle of the night, a digital tool cannot ensure you show up at early morning before work," Dafydd added.

For many, he suggested, the gym is a place to leave phones behind and stop being glued to screens.
