Following a holiday period packed with indulgent treats and relaxation, numerous individuals enter the new year aiming to get their fitness back on track.

But, is it possible that Artificial Intelligence be transforming the fitness industry by offering an alternative to personal trainers?

Tailored Programs and Adaptable Schedules

One fitness enthusiast used an artificial intelligence application for last-minute preparation for the Cardiff Half Marathon.

The 21-year-old from a town in Wales said she liked the freedom to ask it questions at all hours – a feature she believed was unavailable with a personal trainer.

Leah used an AI-powered running app that gave her personalised plans with voice guidance and pace setting for her first long-distance race in 2024.

She said she asked it to design a regimen combining cardio and the gym, and it produced an multi-week programme customized to her event day and objectives.

Leah then adjusted the schedule to suit her lifestyle, which she said was highly practical.

The following year, she chose a alternative application because it was more affordable and she could ask it questions at any time. Her result was a minute faster than her goal time.

She said she did not want feeling pressure from a live instructor.

"Using AI you have to motivate yourself, which I quite like," she remarked.

Remarkable Strength Gains

In a similar case, Another individual, 23, from Swansea, has been employing AI for his fitness and diet plans, and said he has never felt stronger, increasing his bench press from 70kg to 110kg.

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

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

This no-cost application constructed a fitness and meal program tailored to his aims, and established organized workouts.

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

The Expense Contrast: Technology vs. Conventional Training

A recent survey in late 2024 compared costs for 17 of the largest fitness chains and found the typical monthly fee was around £38 per month, based on standard full-access plans.

Fees started at a lower price at the most affordable provider to a premium rate at the highest-priced.

According to further data, fitness coaches set their own rates, typically a range of thirty to sixty-five pounds per hour-long appointment in most areas and about £45-£65 in London.

Clients typically hire a trainer one or two times a week and collaborate for a short period, however these arrangements are completely flexible.

The Essential Human Touch

Fitness coach Dafydd Judd, based in the Welsh capital, acknowledged artificial intelligence can be useful to speed up progress, but believes it will not supplant the human connection and accountability that live training offers.

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

"In my opinion it's very valuable, more knowledge is good," he said.
"I believe the more people are connected digitally the more they'll desire human connection because they crave the empathy from the understanding that is missing from a machine," he continued.

The trainer said Artificial intelligence can educate users and make coaching more efficient.

However, he argued real commitment comes when people show up in person for their sessions.

"No matter how helpful as it is at 2am, a computer cannot ensure you show up at 7am before work," he concluded.

For many, he suggested, the fitness center is a place to disconnect from devices and stop being glued to screens.
