How coaching works in real life

What Coaching Actually Looks Like

Your training plan is only the starting point. The real coaching happens when your schedule changes, recovery drops, a session doesn’t go as expected or race day gets closer.

01Personalized weekly planning

Training Built Around You

Running, cycling, swimming, strength and recovery are planned around your goals, current fitness and the time you actually have available.

Real TrainingPeaks training week: bike intervals, easy runs, strength, mobility and an unavailable day
02Workout review + coach feedback

Your Training Gets Reviewed

Key sessions are reviewed so the next decision is based on how you actually performed — not just what was originally planned.

Example of coach feedback on a reviewed easy run session
03Ongoing plan adaptation

Your Plan Changes When Life Does

Poor sleep, business travel, a late meeting or a missed session shouldn’t derail your training. The week is adjusted while the bigger goal stays the same.

04Race strategy + execution

Race Day Isn’t Left to Chance

Pacing, fueling, preparation and key race cues become part of the coaching process so you know what to do when it matters.

A plan tells you what to do. Coaching helps decide what to do next.

Real-Life Adaptation

Your Week Won't Always Go to Plan.Your coaching shouldn't depend on it.

Work gets busy. Sleep suffers. Travel changes the week. Sometimes a session simply doesn't fit. Good coaching isn't about forcing the original plan — it's about making the right adjustment while keeping the bigger goal on track.

The GFitness Method

A Simple Process. Continuously Adapted.

Understand Plan Train Review Adapt

Good coaching is not about creating the perfect plan once. It is a continuous process of understanding where you are, planning what matters, reviewing what happens and adapting what comes next.

  1. Understand

    Understand You First

    Goals, training history, current fitness, available time, work, travel and recovery all shape the starting point.

    GOALS · LIFESTYLE · TRAINING HISTORY

  2. Plan

    Build the Right Week

    Your endurance, strength and recovery sessions are structured around what will move you forward — and what realistically fits your life.

    ENDURANCE · STRENGTH · RECOVERY

  3. Train

    Execute With Purpose

    Every session has a reason. You know what to do, how hard it should feel and what success looks like.

    PURPOSE · INTENSITY · EXECUTION

  4. Review

    Learn From What Actually Happened

    Key sessions, recovery and progress are reviewed so coaching decisions are based on your real response to training.

    FEEDBACK · PERFORMANCE · RECOVERY

  5. Adapt

    Decide What Comes Next

    The plan evolves with your fitness, schedule and circumstances — while the long-term goal stays in focus.

    ADJUST · PROGRESS · REPEAT

  6. Back into the next planning cycle

Each week informs the next one.

Training becomes more specific as we learn what works for you.

Real Athletes · Real Progress

Built for Real Lives. Proven in Real Training.

Different goals. Different schedules. The same principle: training that fits the athlete instead of forcing the athlete to fit the plan.

Portrait of Christoph, a GFitness athlete preparing for the Vienna City Marathon

Christoph

Busy Professional · Marathon

Goal

Prepare for the Vienna City Marathon 2027 while rebuilding consistent endurance training.

Challenge

A demanding job, regular business travel and little predictable training time. Consistency matters more than following a rigid programme.

Coaching Approach

  • 5–10 hours per week, depending on availability
  • Structured running development with strength work
  • Scheduling adapted around work and travel
  • Regular workout review and feedback

Progress

In progress

Consistency First

Building a sustainable running routine with progressive volume, strength integration and training that fits around frequent business travel.

“Andy takes careful care of all the details — for example a demanding work schedule, holidays and nutrition — to achieve individual, personal goals.”

— Christoph
Portrait of Mario, a CFO coached by GFitness on strength and health

Mario

CFO · Strength, Health & Performance

Goal

Regain strength, improve body composition and build sustainable fitness in his early 50s.

Challenge

A former professional athlete whose old training methods no longer produced results. Previous knee surgeries meant training had to stay challenging without stressing his joints.

Coaching Approach

  • Individualized strength and conditioning
  • Programming adapted around his knees
  • Weekly check-ins and progress tracking
  • Practical nutrition guidance

Result

Stronger. Leaner. Sustainable.

Steady weight loss, visible body-composition changes and improved strength — without unnecessarily stressing his knees.

“It was the first time in years that the effort I put in was also visible and lasting.”

— Mario

Andy Gesellmann, endurance coach and founder of GFitness, in a relaxed portrait
Meet Your Coach

Coaching Built for People With Real Lives.

I'm Andy — endurance athlete, coach and the person behind GFitness.

I built GFitness around a simple idea: training should support your life, not compete with it.

Like many of the athletes I work with, I know what it means to fit training around demanding work, travel and other responsibilities.

The goal isn't to create perfect training weeks. It's to make good decisions consistently — and keep moving toward the bigger goal.

My Coaching Philosophy
A training plan is useful. But the real value of coaching comes from knowing when to follow it, when to adjust it and when doing less is the smarter decision.
  • Endurance Athlete

    First-hand experience balancing endurance training, race preparation, recovery and everyday responsibilities.

  • Certified Coach

    IRONMAN U Certified Coach · Precision Nutrition Level 1

    Evidence-informed coaching translated into practical training decisions.

  • Built for Real Life

    Training designed to work alongside work, travel and other responsibilities.

What Athletes Say

Coaching That Works Beyond the Training Plan.

The best coaching relationship is built on trust, communication and knowing that your training can adapt when life changes.

“Every Sunday I can't wait to get my new training schedule. Andy adapts every workout to my daily routine and keeps me highly motivated.”
Doris · Human Energy Practitioner
“When motivation faded and life got in my way, I always felt I had someone to guide me through the struggles — someone who would listen and understand.”
Susann · Full Time Mum
“Since I started working with Andy, I developed a strong desire to go way beyond what I originally intended to achieve.”
Ben · Business Owner
