Why Do You Give Up When Your Workout Gets Tough? Scientists Reveal a Psychological Trap

The first week, you go to the gym with enthusiasm. By the second week, you’re already starting to feel tired, but the prospect of results keeps you going. The third week brings the first setback. You get held up at work, you don’t feel like going in the evening, and when you look in the mirror, you feel like nothing has actually changed.

And that’s when a subtle thought creeps in: Maybe I’m just not cut out for this.

It’s strange how quickly we can turn a single unpleasant experience into a conclusion about our own abilities. We no longer see a tough workout as a natural part of the process, but as proof that we’ve set a goal that’s too ambitious. But what if the problem isn’t the difficulty itself, but rather the meaning we attach to it? This is precisely the question that American psychologist Daphna Oyserman of the University of Southern California has been researching for a long time.

Two people, the same obstacle. A completely different outcome

Imagine two people who start working out regularly. Both have a similar starting fitness level, a similar workout plan, and the same goal: to get stronger and feel better. After a few weeks, both reach a point where results aren’t coming as quickly as they expected. The first person starts to doubt. If they have to put in so much effort and still don’t see any changes, maybe working out just isn’t for them.

The second person interprets the same situation differently. The results aren’t significant yet because this is a long-term process that requires time, consistency, and gradual adaptation. The difference doesn’t necessarily lie in greater willpower or better genetics. It lies in how they interpret what they’re both currently experiencing.

This is an illustrative example, not a specific experiment with bodybuilders. However, it accurately captures the mechanism addressed by the theory of identity-based motivation.

Researchers have described two ways we perceive difficulty

According to research by Daphna Oyserman, people can interpret a challenging task in two different ways. The first is referred to as “difficulty-as-impossibility.” In this case, we understand difficulty as a signal that the goal is likely unattainable or unsuitable for us.

The second approach, “difficulty-as-importance,” means that we perceive difficulty as a sign that a particular goal matters to us. In an experimental study published in 2018, researchers examined how this interpretation relates to students’ perceptions of their future and their performance on academic tasks.

Participants who were guided to perceive difficulty as a sign of importance achieved better results on some tasks than groups that received a different explanation or none at all. Interestingly, the task itself remained challenging. What changed primarily was the meaning participants attributed to it.

Difficulty, therefore, does not automatically mean we should give up. Sometimes it can simply be part of something we truly care about.

A 2026 Study: Our Mindset Is Not Set in Stone

An even more interesting perspective was provided by a study published on April 24, 2026, in the Journal of Personality. Researchers Alysia Burbidge and Daphna Oyserman analyzed the results of five studies involving a total of 2,746 participants. They examined whether the way difficulty is interpreted is a stable personality trait or whether it can vary depending on the specific situation.

The results showed that both are true.

Although people differ in how they typically think about challenging tasks, their interpretation is not fixed. It can vary depending on the circumstances and context. The study also found that people more inclined to interpret difficulty as an insurmountable obstacle were more likely to prefer easier tasks. Conversely, interpreting difficulty as importance was associated with daily engagement in meaningful activities.

However, this does not mean that simply changing one’s mindset will automatically lead to better athletic performance. The research focused primarily on academic and everyday situations, not on muscle growth or long-term adherence to training plans. However, it offers an interesting explanation of why the way we think can be an important part of perseverance.

Why does this apply to your training?

The biggest obstacle to regular exercise is often not a single exceptionally demanding workout. Much more often, it’s the ordinary days when you don’t feel like it, you’re tired after work, or you feel like your efforts aren’t getting you anywhere.

That’s exactly when it can be helpful to distinguish between two questions.

Is this workout objectively unsuitable, or is it just difficult for me to complete right now?

If you’ve been overworked for a long time, aren’t sleeping well, or are in pain, the right solution might be to rest or change your plan. But if you’re just losing your initial enthusiasm, that doesn’t necessarily mean you’ve chosen the wrong goal. At times like this, try not to judge your entire potential based on a single evening. Skipping one workout doesn’t make you undisciplined. Likewise, one subpar performance doesn’t prove that you’ll never improve.

It might be more helpful to ask yourself: What can I do today to make it easier for me to keep going next week?

When Your Routine Falls Apart, Even Strong Motivation Won’t Help

Your mindset is important, but it’s not enough on its own. If you regularly find yourself unable to fit in a workout, cook a meal, and rest after a demanding workday, another motivational video might not be the solution. Sometimes a better-planned routine, a prepared meal, or a realistic number of workouts per week can help.

The same applies to nutrition. Anyone who wants to build muscle in the long term should also pay attention to getting enough protein. If you’re unable to get enough protein from your regular diet, GymSupps XWhey Protein can be a practical option. It’s a whey protein that combines concentrate, isolate, and hydrolyzed protein.

However, no protein will increase your discipline or change your psychological perception of obstacles. It can only simplify one specific aspect of your diet. And that’s exactly the point: to eliminate unnecessary complications wherever possible, rather than relying solely on willpower every day.

How can you change your mindset when things start to get tough?

Research on how we interpret difficulty offers interesting inspiration for daily training. It’s not some magical mental technique, but a way to create some space between an unpleasant feeling and the decision to quit. Start by noticing your first automatic reaction. When you can’t lift the planned weight, instead of immediately concluding that you’ve hit a plateau, try to examine the circumstances. Did you get enough sleep? Did you increase your training volume too quickly? Is there a problem with your form?

If you skip a workout, you don’t have to consider the whole week a loss. Think about how to adjust the following days so you can keep going. And if you don’t feel like going to the gym, remind yourself why you decided to start in the first place. Not because every workout has to be enjoyable, but because it means something to you in the long run. It’s important not to confuse mental resilience with ignoring your body’s warning signs. Sharp pain, dizziness, injuries, or symptoms of overtraining aren’t obstacles you have to overcome at all costs.

The point isn’t to endure everything. The point is to learn to recognize when it’s worth continuing and when it makes more sense to change your approach.

Maybe you don’t need more motivation. Just a different perspective on obstacles

In the fitness world, there’s often talk of discipline, pushing past limits, and the ability to endure discomfort. But there’s less talk about how we interpret our own difficulties. That’s where the important difference lies. If you see every complication as proof of your own inadequacy, it becomes increasingly difficult to stay connected to your long-term goal.

If, on the other hand, you can view it as information you can work with, it opens the door to another attempt, an adjustment to your plan, or gradual improvement. Daphna Oyserman’s research doesn’t claim that positive thinking automatically builds bigger muscles. However, it does show that the way we interpret difficulty is linked to our decisions, motivation, and willingness to devote effort to important tasks.

And that is precisely the insight worth applying to the gym as well.

Because sometimes it’s not the extra kilogram on the barbell that separates you from your goal. It’s the conclusion you drew about yourself the moment something went wrong.
