Why Some Runners Are Turning to AI Instead of Personal Trainers

A new year reset powered by algorithms

January has long been associated with fresh starts, gym memberships, and renewed fitness goals. After weeks of festive indulgence, many people look for ways to rebuild routines and regain motivation. Increasingly, some are doing so with the help of artificial intelligence. From customised workout plans to real time feedback, AI driven fitness tools are beginning to challenge the traditional role of personal trainers.

For a growing number of users, the appeal lies in accessibility, affordability, and flexibility. Fitness apps powered by AI promise tailored guidance without fixed schedules or ongoing face to face commitments, a shift that reflects wider changes in how people engage with health and technology.

Training for a race with digital support

Leah Walsh, a 21 year old runner from Aberdare in Rhondda Cynon Taf, turned to an AI fitness tool while preparing for the Cardiff Half Marathon. With limited time to train, she wanted a solution that could adapt quickly to her needs. The AI system provided structured sessions, pacing advice, and recovery guidance, allowing her to fit training around work and personal commitments.

What stood out most for Leah was the ability to ask questions at any time. Unlike a personal trainer with limited availability, the AI tool responded instantly, whether she needed clarification on a workout or advice late in the evening. This sense of constant support made the process feel more manageable and less intimidating.

Why AI appeals to a new generation

Younger users, in particular, are driving interest in AI fitness tools. Many are already comfortable using technology to manage daily life, from budgeting to studying, making digital coaching feel like a natural extension. AI platforms can analyse performance data, adjust training intensity, and track progress with a level of consistency that appeals to data focused users.

Cost is another major factor. Personal training sessions can be expensive, placing them out of reach for many people. AI subscriptions often cost a fraction of that price, opening access to guided fitness for a broader audience. For those balancing studies, part time work, or unpredictable schedules, the flexibility can outweigh the benefits of in person coaching.

The limits of machine driven motivation

Despite its advantages, AI fitness is not without drawbacks. Personal trainers offer human connection, accountability, and emotional understanding that technology struggles to replicate. A trainer can notice subtle changes in mood, posture, or confidence and adapt sessions accordingly. They can also provide encouragement in moments when motivation dips, something even the most advanced algorithm may fail to do convincingly.

There are also concerns about over reliance on generic data models. While AI can personalise plans based on input, it may not fully account for injuries, medical conditions, or psychological factors unless users provide detailed information. This places responsibility on individuals to understand their own limits.

A shifting fitness landscape

The rise of AI in fitness does not necessarily signal the end of personal training. Instead, it suggests a more hybrid future. Some trainers are already integrating AI tools into their services, using them to track progress or supplement in person sessions. Others see digital coaching as a gateway, helping beginners build confidence before seeking human guidance.

For users like Leah, AI represents empowerment rather than replacement. It offers autonomy and adaptability at a time when traditional fitness models may feel restrictive or outdated.

What this trend means going forward

As artificial intelligence continues to evolve, its role in personal health is likely to expand. Fitness, once dependent on physical presence, is becoming increasingly digital. Whether AI remains a standalone alternative or becomes a partner to human trainers will depend on how well it balances efficiency with empathy.

For now, the choice reflects individual priorities. Some value human connection, while others prioritise flexibility and control. What is clear is that AI is no longer on the sidelines of the fitness industry. It is actively reshaping how people train, prepare, and stay motivated.
