Following a festive period filled with rich foods and relaxation, many people enter the new year looking to regain their fitness momentum.

However, is it possible that Artificial Intelligence be transforming the fitness industry by providing an option to personal trainers?

Tailored Programs and Flexible Timelines

One fitness enthusiast employed an AI tool for last-minute training for the a major running event.

This young woman hailing from Aberdare said she liked the freedom to ask it questions any time of day – something she felt was unavailable with a traditional coach.

She used an AI-driven fitness application that gave her personalised plans with audio coaching and pace setting for her inaugural half marathon in 2024.

She said she asked it to create a plan merging cardio and the weight training, and it produced an 11-week plan tailored to her race date and goals.

The user then adjusted the schedule to fit her daily routine, which she described was convenient.

Subsequently, she opted for a different tool because it was cheaper and she could consult it whenever she wanted. She finished a full minute quicker than her target finish.

She said she did not want feeling pressure from a human personal trainer.

"With artificial intelligence you have to find your own drive, which I quite like," she added.

Remarkable Strength Improvements

In a similar case, Another individual, 23, from a Welsh city, has been using artificial intelligence for his exercise and nutrition programs, and said he has achieved peak strength, boosting his bench press from a lower weight to a much heavier load.

Richard resorted to a AI assistant for help after being unable to run a running event.

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

This no-cost application built a workout and diet plan personalized to his goals, and created structured routines.

"I work out for about two hours a day and I've seen a real difference," he added.

The Cost Contrast: Technology vs. Traditional Training

One recent study in late 2024 analyzed costs for 17 of the biggest gym brands and found the average membership cost was around £38 per month, for basic full-access plans.

Prices started at £23 at the most affordable provider to £132 at the most expensive.

According to further data, fitness coaches determine their own fees, usually a range of thirty to sixty-five pounds per hour-long appointment in most areas and about £45-£65 in the capital.

Customers typically use a coach once or twice a week and collaborate for a few months, however these arrangements are completely flexible.

The Irreplaceable Personal Element

Fitness coach Dafydd Judd, from Cardiff, said AI can be useful to accelerate results, but is convinced it will never replace the personal interaction and responsibility that in-person coaching offers.

The 37-year-old, who has over a decade of experience as a trainer, focuses on senior clients and injury rehabilitation. He said a number of his clients also use AI.

"I think it's extremely useful, more knowledge is good," he stated.
"I believe the more that people are online the more they'll want human connection because they want the empathy from the understanding that is missing from a computer," he continued.

The trainer said Artificial intelligence can inform users and make guidance more efficient.

However, he said true dedication comes when people show up physically for training.

"As useful as it is at the middle of the night, a computer cannot ensure you show up at 7am before work," Dafydd added.

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