I Swapped My Own Personal Trainer for AI – And It's Working.

After a festive period packed with indulgent treats and downtime, many people head into the new year looking to get their fitness back on track.
However, is it possible that Artificial Intelligence be transforming the world of exercise by offering an alternative to personal trainers?
Tailored Programs and Flexible Timelines
Leah Walsh employed an artificial intelligence application for last-minute preparation for the Cardiff Half Marathon.
The 21-year-old from Aberdare said she liked the liberty to ask it questions any time of day – something she believed was unavailable with a personal trainer.
She relied on an AI-driven running app that provided her personalised plans with voice guidance and speed targets for her first long-distance race 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 race date and objectives.
The user then adjusted the schedule to fit her daily routine, which she said was highly practical.
The following year, she chose a alternative application because it was more affordable and she could consult it whenever she wanted. She finished a minute faster than her goal time.
She noted she did not want feeling pressure from a human personal trainer.
"Using AI you have to motivate yourself, which I actually prefer," she remarked.

Remarkable Strength Gains
In a similar case, Richard Gallimore, 23, from Swansea, has been employing artificial intelligence for his fitness and diet plans, and said he has achieved peak strength, increasing his bench press from a lower weight to 110kg.
He resorted to a AI assistant for assistance after being forced to walk a running event.
"I realized I need to get myself in shape," he commented.
The free tool constructed a workout and diet plan tailored to his aims, and established organized workouts.
"I train for about 120 minutes a day and I've seen a real difference," he added.
The Cost Comparison: AI vs. Traditional Training
One recent study in late 2024 compared costs for 17 of the biggest fitness chains and found the typical monthly fee was around £38 per month, for basic memberships.
Fees started at £23 at the cheapest chain to a premium rate at the most expensive.
According to industry research, personal trainers set their own rates, usually £30-£65 per 45-60 minute session in most areas and about £45-£65 in the capital.
Clients typically use a trainer once or twice a week and work with them for a short period, but these arrangements are often adaptable.

The Irreplaceable Human Touch
Personal trainer one experienced professional, from Cardiff, acknowledged AI can be useful to speed up progress, but believes it will not supplant the personal interaction and accountability that in-person coaching provides.
The 37-year-old, who has 12 years experience as a coach, specialises in older adults and recovery from injuries. He said some of his trainees also employ AI.
"In my opinion it's extremely useful, additional information is positive," he said.
"I think the more people are connected digitally the more they'll desire personal contact because they want the warmth from the understanding that is missing from a computer," he added.
The trainer said AI can inform clients and make guidance more effective.
However, he argued real commitment comes when people show up physically 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 gym is a space to disconnect from devices and take a break from technology.
