After a holiday period filled with rich foods and downtime, numerous individuals head into January looking to regain their fitness momentum.

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

Tailored Programs and Flexible Schedules

Leah Walsh used an artificial intelligence application for impromptu preparation for the Cardiff Half Marathon.

The 21-year-old from a town in Wales explained she appreciated the freedom to ask it questions any time of day – something she felt was not possible with a personal trainer.

Leah relied on an AI-powered running app that provided her customized schedules with voice guidance and speed targets for her inaugural half marathon in 2024.

She explained she requested it to design a regimen merging cardio and the gym, and it produced an 11-week plan customized to her race date and goals.

The user 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 ask it questions at any time. She finished a minute faster than her target finish.

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

"With AI you have to motivate yourself, which I actually prefer," she added.

Significant Strength Improvements

Meanwhile, Another individual, in his twenties, from Swansea, has been using artificial intelligence for his exercise and nutrition programs, and said he has never felt stronger, boosting his chest press from 70kg to a much heavier load.

He resorted to a AI assistant for assistance after being unable to run a race.

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

This no-cost application built a workout and diet plan personalized to his aims, and established organized workouts.

"I work out for about 120 minutes a day and I've seen a noticeable change," he said.

The Cost Contrast: AI vs. Traditional Coaching

One recent study in late 2024 analyzed costs for 17 of the biggest fitness chains and found the typical monthly fee was around £38 per month, based on basic memberships.

Fees started at a lower price at the cheapest chain to a premium rate at the highest-priced.

According to industry research, fitness coaches determine their own fees, typically a range of thirty to sixty-five pounds per 45-60 minute appointment in most areas and about £45-£65 in the capital.

Customers will often use a trainer once or twice a week and collaborate for a short period, but these agreements are completely flexible.

The Irreplaceable Personal Element

Fitness coach Dafydd Judd, based in Cardiff, said artificial intelligence can be beneficial to speed up progress, but is convinced it will not supplant the personal interaction and accountability that live training provides.

This expert, who has 12 years experience as a coach, specialises in senior clients and recovery from injuries. He said some of his clients also employ AI.

"I think it's extremely useful, additional information is good," he stated.

"I believe the more people are online the more they'll want human connection because they crave the warmth from the comprehension that is absent from a machine," he continued.

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

However, he argued real commitment comes when people appear physically for training.

"No matter how helpful as it is at the middle of the night, a digital tool cannot ensure you show up at early morning before work," he added.

For many, he said, the gym is a space to leave phones behind and take a break from technology.
