Let’s be clear from the start: this is not about creating a training program based on experience, hearsay, or the latest trend you saw online. Too many programs out there resemble a random stew — a bit of sprint work here, some HIIT training there, mixed with threshold, FatMax, and Zone 2 sessions — without a clear structure or purpose. The training program is like your tactics – how to reach a goal. But without the right strategy the tactics will fail.

Tactics without strategy are the noise before defeat. Sun Tzu

Creating a training program starts with a clear goal. Based on that goal we need a strategy on how to reach this goal. And then the tactics: these are the actual workouts and plan to implement the strategy

This article isn’t about a training philosophy. It’s about the process — the critical steps that ensure a training program is actually successful. 

And what do we mean by successful? A successful training program is one that, given real-world constraints — such as available training time, access to facilities, and the athlete’s ability to recover alongside work and social life — delivers the highest possible performance improvement under those circumstances.

By the end of this article, you’ll walk away with a clear, actionable framework. A framework that, when followed, enables you to design training programs that are consistently successful — using the definition above. Applying these principles, and creating an effective training plan becomes not just possible, but straightforward.

Before diving deeper into the article, watch INSCYD founder Sebastian Weber explain the exact 5-step framework used by the world’s most successful endurance coaches.

👉 Watch the video below to see how the process works in practice.

Now that you’ve seen how the framework works, explore the detailed breakdown in this article.

You’ll get a step-by-step manual on turning physiological data into smarter, goal-driven training plans. Let’s get started.

Step 1: Start From the End

The best way to think about a training program is this: it’s a description of how to get from point A to point B in the shortest possible time. Just like a GPS navigation system finds the fastest route to your destination, a well-designed training program does exactly the same — it shows you the most effective path from your current performance level to your goal.

That’s why every successful training program must start at the end — with a clear definition of the goal. Without knowing exactly where the athlete wants to go, it’s impossible to know what kind of training is needed to get there.

Consider this: the most effective program to become a better sprinter is completely different from the one needed to run a faster marathon. The destination determines the route.

However, athletes can only describe their goals in terms which won’t allow you to immediately decipher the real goal — “I want to run a marathon,” “I want to cut an hour off my Ironman time,” or “I want to be a better climber.” These sound specific, but they’re not. It’s like telling your GPS, “I want to go to a restaurant.” Even if you specify which restaurant, your navigation still needs exact coordinates to calculate the route.

It’s the same in training. To design the best possible program, you first need to define exactly what the output should be — the precise, measurable goal you’re aiming for. That’s what we’ll tackle in the next step.

“When you’re heading in the wrong direction, there’s no point in increasing your speed.”

Step 2: Strategy - Translate the Goal Into a Destination

Once the goal is known, the next step is to make it specific enough that it can serve as a true destination — something precise you could enter into your “training GPS.” A GPS can’t calculate a route to “somewhere nice”; it needs exact coordinates. Similarly, a training program can only work when the desired outcome — the intended adaptation — is clearly defined.

At this stage, we are not yet deciding which strategy to take. Instead, we’re recognizing that there are multiple possible routes aka strategies to reach the same goal.

Take a marathon, for example. The goal “run a faster marathon” sounds clear, but there are many ways aka strategies to achieve it. Performance could improve by increasing VO₂max, by improving fat oxidation, by reducing body weight, or by enhancing running economy. 

Each of these strategies could lead to a better marathon result — yet each would require a completely different training approach. A program with increased training load to raise VO₂max will look nothing like a nutrition-focused plan to reduce body weight, and both will differ from a program designed to improve running economy.

The same logic applies to a road cyclist who wants to win races. One athlete might need to increase sprint power to outsprint competitors. Another might already have enough sprint power but needs to arrive at the finish line less fatigued.

No matter the sport or the goal, the principle remains the same: different strategies can be used to reach the same goal. Understanding that there are multiple possible routes is essential before choosing the right one.

In the next step, we’ll discuss how to determine which of these strategies is the correct one for your athlete.

Step 3: Define the Starting Point

Think back to the analogy of a training program as the shortest route between point A and point B.

If point B is the goal, then we must first know where point A is — our starting point. 

Without knowing where you are, it’s impossible to navigate any route, no matter how good your map or GPS might be. The same applies for your training program: without knowing precisely the starting point aka current athletic performance status, it simply is not effective to start training.

“When you’re heading in the wrong direction, there’s no point in increasing your speed.”

Before taking any action, a coach must establish the athlete’s current performance status. That’s where performance assessment comes in. The more comprehensive and precise the assessment, the better the training decisions will be.

Think of it like prescribing a diet: no coach would design a nutrition plan to reduce body weight without first knowing the athlete’s actual weight. And if that weight were only known with an accuracy of ±10 kg, the coach would hesitate to act — because the foundation is too uncertain.

It’s the same with training. We need all data points that could be relevant, we need them measured accurately, and ideally, we need as many as possible. Sometimes, what looks like “too much data” later turns out to be exactly what explains a hidden pattern or unexpected limitation.

A complete performance assessment should therefore include — at minimum — the following key parameters and why they matter:

  1. VO₂max – The maximal aerobic capacity, the main energy contributor for almost all exercise lasting longer than one minute.
  2. VLamax – The anaerobic power, which informs not only sprint capability but also carbohydrate sparing, fat combustion rates, and thresholds such as LT2 or MLSS.
  3. Substrate Utilization (FatMax, MFO) – Knowing the rate at which fat and carbohydrates are burned is essential, since carbohydrates are a limited and valuable fuel source. Training at or near FatMax is often the most efficient way to improve aerobic capacity.
  4. Thresholds (LT1, MLSS, etc.) – These help monitor progress, define training zones, and connect physiological data with real-world performance.
  5. Glycogen Status – Glycogen is the body’s high-octane fuel, but it can be depleted within just over an hour of intense exercise. Replenishing it takes 48–72 hours, which has major implications for training frequency and recovery.
  6. Lactate Accumulation Rate – Indicates how quickly lactate builds up (in mmol · L⁻¹ · min⁻¹), reflecting time to fatigue and muscle acidosis.
  7. Lactate Clearance – Shows how efficiently lactate is removed from the muscle and blood, a key marker for recovery capacity and endurance performance.

In short: without a clear understanding of where your athlete stands today, you can’t determine the most effective way to get them to their goal tomorrow.

💡 Coach’s Insight

A comprehensive performance assessment doesn’t have to be time-consuming or require a lab.

With modern testing methods like INSCYD, all of these key metrics — from VO₂max to lactate clearance — can be measured in less than 30 minutes, using only field data from cycling or running tests.

Step 4: Contrast the Status Quo with the Goal

Now that we know where we are and where we want to go, the next step is to determine how to get there — the actual route between point A and point B. This is where we define the training strategy.

Should the focus be on increasing VO₂max by raising training volume or intensity?

Would it be more effective to keep the training load constant but adjust nutrition to reduce body weight?

Or perhaps the best approach is to improve movement efficiency, such as enhancing running economy?

These are the kinds of questions that leave many coaches stuck — not because they don’t know the science, but because they don’t have the tools to see where the biggest performance gains can be made. In other words: how to find the “how.”

This is exactly where the INSCYD Virtual Test comes in.

How it works

Based on a real performance assessment — whether it’s a quick lactate test (20–25 minutes) or a remote test with just four all out efforts ranging from 20 seconds to 8 minutes — a virtual copy of the athlete’s profile is created.

Imagine having a dashboard in front of you showing all the key metrics: VO₂max, VLamax, FatMax, thresholds, substrate utilization, and more. Now you duplicate that profile and can freely “play” with the numbers:

  • Want to know what happens if aerobic capacity increases? Adjust VO₂max and see the effect on fat combustion.
  • Curious about how lowering VLamax affects carbohydrate sparing or threshold performance? Try it.
  • Wondering how reducing body weight influences running pace? Test it virtually.
  • Thinking about whether improving running economy is worth the effort before a 10 km race? You’ll see the outcome instantly.

By comparing the modified copy to the original assessment, you can simulate different training strategies and immediately see which physiological adaptation yields the biggest performance improvement.

That’s how you identify the most efficient route — the strategy that gives you and your athlete the biggest return on training investment.

And there’s a powerful side effect: you can show it to your athlete. Visualizing why a specific approach was chosen transforms motivation and trust. When athletes see proof that their plan is based on data, not guesswork, adherence and confidence rise dramatically.

Step 5: Bring It All Together – the Training plan

Now you can finally bring everything together.

You’ve defined a goal, translated that goal into specific metrics, and — by contrasting these metrics with the athlete’s current status — you’ve used performance projections to identify which metric to focus on.

Only now does it make sense to talk about the training program itself — the tactics.

Because now, you know exactly what you want to improve. From the once-random stew of training methods, you can now select only those that truly contribute to your defined goal. 

Instead of having one or two sessions per week that by chance move the athlete in the right direction, every single session can now be purposeful and aligned with the strategy.

Design your program around that strategy — choose the right methods, the right interval structures, the right training zones, the optimal recovery times, and the appropriate nutrition support.

This is where your coaching experience, creativity, and understanding of the athlete’s real-world constraints — time, work, and family — come into play.

And here’s the best part: once you’ve built this foundation and created the first program (for example, a weekly plan), extending it into a longer training phase becomes surprisingly straightforward.

Yes — it’s mostly copy and paste.

That may sound uninspired, but it’s actually the opposite.

By this point, you’ve done the heavy lifting: analyzing, quantifying, and deciding what truly drives performance for your athlete. Once that is known, there’s no reason to deviate from what works. Repetition is not laziness — it’s progress through consistency.

Training adaptations don’t happen through variety alone; they happen through repeated, targeted exposure to the right stimuli. So repeating the correct and effective workouts isn’t just efficient — it’s the most reliable way to achieve the goal.

Conclusion: From Guesswork to Precision

Creating a training program doesn’t have to rely on gut feeling, trends, or a mix of everything that might work. When you follow a structured process — defining the goal, translating it into metrics, assessing the starting point, identifying the right strategy, and finally executing with precise tactics — success becomes predictable, not accidental.

This is not about training harder; it’s about training right. It’s about replacing guesswork with data, uncertainty with clarity, and opinion with proof.

When you apply this process, you’ll notice something remarkable: designing an effective training program suddenly feels simple. Because it is — once you have the right framework.

And when your athletes see their results improve, session after session, you’ll know that what drives their progress isn’t luck, but your ability to connect science, strategy, and coaching experience into one powerful system.

That’s what successful training looks like.
