I Replaced My Fitness Coach for AI – And It's Effective.

After a festive period packed with rich foods and downtime, many people enter January looking to get their fitness back on track.
However, could AI be changing the fitness industry by offering an alternative to human coaches?
Tailored Programs and Adaptable Timelines
One fitness enthusiast used an artificial intelligence application for impromptu preparation for the Cardiff Half Marathon.
This young woman from a town in Wales said she appreciated the freedom to ask it questions at all hours – a feature she believed was not possible with a traditional coach.
She relied on an AI-driven fitness application that gave her personalised plans with voice guidance and pace setting for her first half marathon in 2024.
She said she requested it to create a plan merging cardio and the gym, and it generated an multi-week plan tailored to her event day and objectives.
The user then tweaked the plan to suit her daily routine, which she described was highly practical.
The following year, she opted for a alternative application because it was cheaper and she could ask it questions at any time. She finished a full minute quicker than her target finish.
She noted she did not want the pressure from a live instructor.
"Using artificial intelligence you have to find your own drive, which I actually prefer," she added.

Remarkable Strength Gains
Meanwhile, Another individual, 23, based in Swansea, has been using AI for his exercise and nutrition programs, and said he has never felt stronger, increasing his chest press from 70kg to 110kg.
Richard resorted to a bot for assistance after being unable to run a running event.
"I realized I had to get myself in shape," he said.
This no-cost application built a fitness and meal program tailored to his aims, and established structured routines.
"I work out for about two hours a day and I've seen a noticeable change," he said.
The Expense Comparison: AI vs. Conventional Training
One recent survey in late 2024 compared prices for 17 of the biggest fitness chains and found the typical monthly fee was approximately forty pounds per month, based on basic full-access plans.
Fees started at £23 at the most affordable provider to a premium rate at the most expensive.
Based on further data, personal trainers determine their own fees, typically a range of thirty to sixty-five pounds per 45-60 minute session in most areas and about £45-£65 in London.
Customers typically use a coach once or twice a week and collaborate for a short period, however these agreements are often adaptable.

The Irreplaceable Human Element
Personal trainer one experienced professional, based in the Welsh capital, said AI can be beneficial to speed up progress, but is convinced it will not supplant the personal interaction and responsibility that in-person coaching provides.
The 37-year-old, who has 12 years experience as a trainer, specialises in senior clients and recovery from injuries. He said some of his trainees also use AI.
"I think it's extremely useful, additional information is positive," he said.
"I think the more that people are online the more they'll want human connection because they want the warmth from the comprehension that is missing from a computer," he added.
Dafydd said AI can educate users and make coaching more efficient.
However, he said real commitment comes when people show up in person for their sessions.
"As useful as it is at 2am, a computer cannot ensure you show up at early morning before work," Dafydd concluded.
For many, he said, the gym is a space to disconnect from devices and take a break from technology.
