Between back-to-back meetings in the CBD and the humidity of a Singapore afternoon, it is easy to see why stress is a constant topic of conversation among our clients. But not all stress is created equal. Understanding how to navigate it is a skill, much like perfecting your squat form or hitting your protein targets. We often bucket all pressure under one label, but if you want to perform better at work and in the gym, you need to distinguish between the two primary types of stress.
Eustress: The Stress That Moves You Forward
Think of eustress as 'good stress.' It is the physiological and psychological response to a challenge that you perceive as manageable and exciting. When you sign up for your first 5km run or tackle a high-stakes presentation, that jittery feeling is eustress. It sharpens your focus, increases your energy, and helps you adapt. In our personal training sessions, we intentionally apply eustress. By challenging your muscles with progressive overload, we force your body to adapt and grow stronger.
Distress: The Friction That Wears You Down
Distress is the negative version. It occurs when the demands placed on you exceed your perceived ability to cope. This is the burnout you feel after a month of poor sleep, bad diet, and constant deadlines. Unlike eustress, distress doesn't lead to growth; it leads to stagnation, fatigue, and injury. When you are constantly in a state of distress, your recovery is compromised, making it impossible to see progress in your fitness goals.
The Yerkes-Dodson Law: Finding Your Sweet Spot
There is an optimal level of stress where we perform at our best. If you have too little, you are bored; too much, and you crash. This relationship is defined by the Yerkes-Dodson Law. As you can see below, performance increases with physiological arousal, but only up to a point.
How to Increase Your Tolerance
Your capacity to handle stress is not fixed. Just as you build resilience through training, you can raise your 'stress ceiling' by:
Prioritizing Recovery: You cannot out-train a lack of sleep. If you are struggling to manage your load, book a free consultation to discuss how to balance your training intensity.
Reframing Challenges: Learn to view difficult tasks as opportunities to grow rather than threats to your wellbeing.
Consistency over Intensity: You do not need to hit a personal best every single time. Consistency in your habits provides the stability needed to buffer against life's unpredictability.
Stress is a flow, not a wall. Your tolerance will fluctuate depending on your work load, your nutrition, and your sleep quality. The goal isn't to live a life without stress, but to master the art of knowing when to push and when to recover. Stay optimal, stay focused.
