Swansea Man Swaps Personal Trainer for AI, Gets Stronger

AI Fitness Coaching: Real Results, Lower Costs
AI vs Personal Trainer

• Key Takeaways:

  • A 23-year-old Swansea gym-goer used AI to build workout and diet plans, increasing his bench press from 70kg to 110kg.
  • A 21-year-old runner used AI training for the Cardiff Half Marathon and improved her time by one minute.
  • Trainers say AI speeds learning and planning but cannot fully replace human accountability and connection.
  • Cost comparisons: average UK gym membership ~£38/month (Which?) and personal trainer sessions typically £30–£65.

AI in everyday training: real people, measurable gains

Richard Gallimore, 23, from Swansea switched to AI-created workout and nutrition plans after feeling "unfit." He says the result has been dramatic — his bench press rose from 70kg (150lb) to 110kg (240lb) and he now trains about two hours a day.

Leah Walsh, 21, from Aberdare used an AI tool to prepare an 11-week hybrid running-and-gym schedule for the Cardiff Half Marathon. The tailored plan helped her shave a minute off her previous time and finish in 2:11.

How people are using AI tools

Users report that AI platforms offer customized schedules, specific time or pace targets, and on-demand Q&A. Leah highlighted convenience and the ability to tweak plans instantly to fit work and life demands.

Richard said AI made structured routines and nutrition guidance accessible and free in his pocket, allowing him to progress at his own pace without paying for a personal trainer.

Costs and market context

A Which? survey (Nov 2024) found the average UK gym membership cost is about £38 a month, with chains ranging from £23 to £132. Research from PureGym notes personal trainers usually charge about £30–£65 per 45–60 minute session outside London, and £45–£65 in London.

That pricing gap helps explain why some people opt for AI-driven plans to save money while still getting structured coaching.

Where AI helps — and where human coaches still matter

Personal trainer Dafydd Judd, with 12 years’ experience, says AI can "speed up progress" and educate clients, but stresses the enduring value of human connection and accountability.

"A computer won't keep you accountable at 07:00 before work," he said, arguing many clients want warmth and in-person guidance that AI currently cannot replicate.

Bottom line

AI fitness tools are delivering tangible results for motivated users by offering cheaper, flexible programs and nutrition advice. However, for many people the human elements of real-time accountability, injury management, and interpersonal support keep personal trainers relevant.
