The role of a personal trainer goes far beyond counting reps or demonstrating exercises. Clients often underestimate how much energy and behind-the-scenes work a trainer puts into each session — until the trainer isn’t there and they have to do it themselves. Many admit they get tired just loading and unloading the bar!

The Physical Effort Behind the Session

During in-person workouts, I’m constantly moving — setting up equipment, adjusting weights, correcting form, and ensuring everything flows seamlessly. It might look effortless, but behind that smooth execution lies a steady stream of physical work and mental focus to create an effective, safe, and engaging experience for each client.

The Virtual Shift

With the rise of virtual consultations, the setting has changed, but the energy demand hasn’t. Even while sitting at my computer, I’m fully engaged — cueing clients, monitoring movement quality, and staying mentally sharp.

I also have a habit of shaking my legs while coaching, which research shows can significantly increase energy expenditure (study link). Between sessions, I include short “exercise snacks” — quick bursts of movement to stay active and focused throughout the day.

Beyond the Session

The effort doesn’t stop when the session ends. Trainers spend hours preparing programs, reviewing client progress, and fine-tuning exercise plans to ensure continued results. It’s a profession fueled by passion, purpose, and a genuine commitment to helping others improve their health and performance.

I’d love to see a study quantifying how much energy a personal trainer expends in a typical workday — I’m willing to bet it’s surprisingly high!

The Unseen Commitment

Whether on the gym floor or through a screen, the true value of a personal trainer lies in the unseen effort — the dedication, energy, and care invested in every client’s journey. It’s this hidden work that defines the essence of personal training.
