Pushing yourself to the limit in every training session won’t automatically make you faster – quite the opposite. Find out what really matters when it comes to sustainable endurance training.

The trap of always pushing too hard

“No pain, no gain” – few training mottos have stood the test of time quite like this one. At first, the basic idea sounds convincing: if you want to succeed, you have to work hard. But constantly pushing yourself to your limits can put too much stress on your body. Like the ebb and flow of the tide, periods of high training stress need to be followed by sufficient recovery. Without it, performance can stagnate – or you may end up burned out. This is particularly true for people who are already under a lot of pressure in everyday life. With limited time available, it can be tempting to push harder during training in an attempt to get as much as possible out of every session. And that’s exactly where the trap lies: Many recreational athletes spend too much of their training time in a moderate heart-rate zone – too hard to allow proper recovery, but not hard enough to provide a meaningful training stimulus. The goal is to create enough variation in intensity and keep your endurance sessions easy enough that they don’t compromise your ability to perform during your high-intensity workouts.

Easy, long and deliberately hard

Experienced endurance athletes do around 80 per cent of their training at an easy pace, staying in what’s known as the “green zone”. Only around 20 per cent of their sessions are genuinely hard. The important thing is that these hard 20 per cent aren’t simply about pushing yourself to complete exhaustion. Instead, it’s about training with intention – approaching every session consciously and intelligently, and training exactly as planned or in a way that serves the goal of the session. When you train hard, do it with purpose and control – not on impulse and not by pushing yourself to the limit every time.

For the easy sessions, the rule is simple: longer is often better than harder. Rather than trying to complete an easy run as quickly as possible or adding a hard interval to it, it’s often more beneficial to keep the entire session at an easy pace. These longer, steady sessions are precisely what trigger the key adaptations your body needs to improve endurance.

Recognising the green zone

How can you tell if you’re in the green zone without having to visit a lab? It’s simple: use the talk test. If you can have a relaxed conversation with your training partner while still taking in your surroundings, you’re generally in the right zone. If your breathing becomes noticeably heavier, your focus narrows and conversation becomes more difficult, you’ve moved into the yellow or red zone. A heart-rate monitor can also help you keep yourself honest – especially when you’re starting out and haven’t yet developed a feel for your own training zones.

For most recreational athletes, extremely hard training offers little additional benefit. Occasional hard sessions at around 90 per cent of your maximum heart rate are more than enough. Professionals generally opt for hard and longer rather than extremely hard and shorter – probably because they’re better able to recover from it.

Conclusion 

It all comes down to one simple but effective principle: consistency beats ambition. Keep most of your sessions deliberately easy and use hard training stimuli purposefully and intentionally. You’ll not only train more effectively, but also stay motivated and injury-free in the long run. After all, sport should become part of your life – and there should always be room for enjoyment.
