Exercise is increasingly recognized as a vital non-pharmacological component of mental health and psychological well-being. With one in five adults experiencing mental illness each year, there is a growing need for integrative and comprehensive modalities that effectively support mental health. Physical activity has emerged as a powerful tool in this regard, offering a natural way to enhance psychological well-being.
This article will explore how exercise impacts mental health, with a special emphasis on self-esteem, highlighting its role in reducing symptoms of anxiety and depression and improving overall quality of life.

The Psychological Benefits of Exercise
Regular physical activity has long been associated with numerous psychological benefits. Research consistently shows that exercise contributes to anxiety reduction, mood improvement, and better cognitive function, which collectively support psychological well-being.
Engaging in physical activity has been demonstrated to reduce symptoms of anxiety and depression. For example, a meta-analysis published in JAMA Psychiatry that included fifteen studies and over 190,000 participants found that there is a relationship between the amount of physical activity someone does and how much it affects their depression. Even levels of exercise below public health recommendations were shown to be effective at treating and preventing symptoms of depression.
One of the primary biochemical mechanisms behind these psychological benefits is the release of endorphins, often referred to as "feel-good" hormones. Endorphins are neurotransmitters that act as natural painkillers and mood elevators, which can alleviate stress and produce a sense of euphoria post-exercise, commonly known as the "runner's high." Additionally, exercise stimulates the release of other neurotransmitters such as serotonin, dopamine, and norepinephrine, which, among other functions, play roles in regulating mood.
Furthermore, regular physical activity enhances cognitive function, improving decision-making, memory, and overall mental acuity. Exercise promotes neurogenesis (the process of creating new neurons, or brain cells), particularly in the hippocampus, a brain region essential for learning and memory.
What Is Self-Esteem?
Self-esteem is defined as a person's overall sense of self-worth or personal value, reflecting how much they appreciate and like themselves. High self-esteem is considered to be a strong determining factor and influencer on mental health, as it contributes to self-confidence, resilience, and a positive outlook on life. (25)
On the other hand, low self-esteem is often linked to feelings of worthlessness and depression. People with low self-esteem are at a greater risk of anxiety, depression, self-harm, suicidal ideation, and disordered eating. (4, 19)
According to research published in the Journal of Personality and Social Psychology, various factors collectively shape how individuals perceive themselves. These may include:
- Body image
- Personal and professional achievements
- Social interactions and relationships
- Socioeconomic status
- Health problems
Exercise and Its Impact on Self-Esteem
Regular exercise has a significant positive impact on self-esteem through various mechanisms. Since the 1980s, psychologists have elucidated that physical activity affects self-esteem through four key areas: motor skills, physical condition, physical fitness, and physical attractiveness (31).
Engaging in physical activity can lead to improved body image. When individuals are active and see changes in their bodies, they often feel more confident and satisfied with their physical appearance. A systematic review published in 2022 found a negative association between physical activity and body image dissatisfaction. In other words, body image dissatisfaction decreases as physical activity levels increase. Even moderate exercise has been associated with immediate improvements in body image perception, regardless of actual fitness level or body changes.
Exercise also provides a sense of mastery as individuals set and achieve personal goals, which boosts self-efficacy and self-worth. The ability of exercise to improve individuals' sense of control over their own bodies has been shown to benefit those who have suffered traumatic events.
Social isolation increases the risk of significant health issues, such as anxiety, depression, suicidal ideation, and dementia, by 25%. One often overlooked benefit of engaging in exercise is the opportunity it provides for social interaction. Participating in group fitness activities, such as classes, sports, or group runs, allows individuals to connect with others, build friendships, and experience a sense of community. Positive interactions and support from others in a fitness setting can foster feelings of belonging and acceptance, which are essential for psychological well-being.
Exercise Modalities and Psychological Wellbeing
Aerobic exercise, including jogging, swimming, cycling, walking, and dancing, is well-known for its positive effects on mood and mental health. The reductions in anxiety and depression caused by partaking in aerobic exercise can be attributed to its ability to release endorphins, increase blood circulation to the brain, and modulate the hypothalamic-pituitary-adrenal (HPA) axis (26). According to one study, participating in three sessions of aerobic exercise three times weekly, each lasting 45-60 minutes, for 12 weeks positively influences self-esteem and mental health.
Resistance, or strength, training, which focuses on building muscle and improving physical strength, has been found to improve cognitive function, self-esteem, and mental health across several clinical trials. According to one study, low-to-moderate intensity strength training is sufficient in producing anti-anxiety effects.
Yoga, a mind-body exercise modality, combines physical postures, breathing techniques, and meditation to enhance both physical and mental well-being. Numerous studies suggest that yoga can reduce stress, improve mood, and enhance overall psychological and cognitive health by promoting relaxation and mindfulness. Research shows that you can begin to see these health benefits as soon as four weeks after initiating a regular yoga practice.
Selecting exercise modalities that align with personal preferences is key to sustained engagement and maximizing psychological benefits. Whether someone enjoys the rhythmic movement of aerobic exercise, the empowering experience of lifting weights, or the calming practices of yoga, finding a preferred activity can lead to greater consistency, enjoyment, and positive outcomes for mental health and self-esteem.
Overcoming Barriers to Exercise
Many individuals face common barriers to exercise, which can hinder their ability to engage in regular physical activity. These often include:
- Lack of time
- Lack of motivation and energy
- Lack of resources
- Feelings of uncertainty
- Physical limitations
Setting realistic and achievable goals can be an effective strategy for overcoming these barriers to exercise. SMART goals can help individuals create a clear roadmap for their exercise journey, enhancing motivation and providing a sense of accomplishment as each goal is met.
SMART is an acronym for goals that are:
- Specific
- Measurable
- Attainable
- Relevant
- Time-bound (12)
For instance, a goal could be to walk 30 minutes a day, five times a week, to improve cardiovascular health, or to perform strength training exercises three times a week to build muscle.
Finding social support and enjoyable activities that align with personal interests will also help you meet these goals once they are created. Engaging with friends, family, or exercise groups can provide encouragement, accountability, and enjoyment.
Developing a Personalized Exercise Plan
Developing a personalized exercise plan can help individuals achieve their physical health goals and maintain long-term engagement.
A successful plan should consider:
- Individual fitness levels
- Fitness goals
- Personal interests
The first step in creating a personalized exercise plan involves assessing the current fitness level. This includes evaluating cardiovascular endurance, strength, flexibility, and any physical limitations. Understanding where one stands helps in setting realistic and attainable fitness goals.
Once your fitness levels have been determined, follow the SMART criteria to set clear fitness goals.
Professional guidance from fitness experts or healthcare providers is invaluable in crafting and adjusting a personalized exercise plan. Experts can provide insights into safe and effective exercise techniques, help prevent injuries, and offer modifications tailored to individual needs. Regular check-ins with a professional can promote accountability for your goals and ensure that the plan evolves with your progress, helping to maintain engagement and continuously challenge your body.
