Confidence isn't just an abstract concept or a feeling that some people naturally possess while others don’t. It's a skill that can be developed and strengthened, much like a muscle. At LVLTN, we believe in empowering individuals to build confidence through evidence-based strategies, in and out of the gym.

Let's delve into the science behind building confidence and how you can apply these principles to your own life.

Understanding Confidence…

Confidence is the belief in your ability to succeed in specific situations. It stems from a combination of:

  • Self-esteem (how you feel about yourself)
  • Self-efficacy (your belief in your ability to accomplish tasks and reach goals)

Research has shown that confident individuals are more likely to take on challenges, persist through difficulties, and achieve their goals.

The Brain-Confidence Connection:

Neuroplasticity

Our brains are incredibly adaptable. Neuroplasticity refers to the brain's ability to reorganize itself by forming new neural connections. When you practice confident behaviors and positive thinking (hello mindfulness), you strengthen these neural pathways, making confidence a more natural part of your behavior.

Dopamine

This neurotransmitter is often referred to as the "feel-good" chemical. Achieving small goals and making progress can trigger dopamine release, reinforcing positive behavior and enhancing your overall sense of confidence.
Ever heard of the term “runner’s high”?

Evidence-Based Strategies for Building Confidence:

Set Achievable Goals

Setting and accomplishing small, manageable goals can create a positive feedback loop. As you achieve these goals, your brain releases dopamine, boosting your confidence and motivating you to tackle bigger challenges.

Visualization

Visualizing success can activate the same neural circuits in the brain as actually performing the task. Spend a few minutes each day imagining yourself succeeding in your goals. This mental rehearsal can increase your self-efficacy and prepare you for real-life situations. You can even practice this through journaling as well.

Positive Self-Talk

The language you use with yourself matters. Positive self-talk can counteract negative thoughts and increase your self-esteem.

Phrases like "I can do this" and "I am capable" can rewire your brain to adopt a more confident outlook.

Let me mention journaling again — create a mantra and write it down.

Body Language

Your physical stance can influence your mental state. Adopting "power poses" (e.g., standing tall with open, expansive postures) can lead to a boost in confidence.

Practice Resilience

Confidence isn't about never failing; it's about how you respond to failure. Developing resilience by learning to view setbacks as opportunities for growth can help maintain and build confidence over time. Techniques like mindfulness and cognitive restructuring can aid in developing a resilient mindset.

Mastery Experiences

According to psychologist Albert Bandura, mastery experiences are the most effective way to build self-efficacy.

Engaging in tasks where you can develop and demonstrate competence gradually builds your confidence.

Start with tasks within your skill range and gradually increase the difficulty as your confidence grows.

Final Thoughts

Building confidence is a journey that involves understanding the science behind it and applying practical strategies consistently.

By leveraging neuroplasticity, dopamine, and evidence-based techniques like goal-setting, visualization, positive self-talk, and resilience training, you can cultivate a strong sense of confidence that will empower you in all areas of your life.
