Self-doubt is like mental poison. I’ve seen it thousands of times in my 35+ years in the fitness industry… people with genuine potential to transform their bodies sabotaging themselves before they even start. Not because they lack information or ability, but because they don’t believe in themselves. They doubt themselves. Then they get trapped in a cycle of self-doubt, overthinking, and “paralysis by analysis.”
As the No-BS Body Transformation Coach, I’m here to tell you that your mind is often the biggest obstacle between you and the body you want. Fixing your mental approach doesn’t require acquiring more and more special knowledge—it requires decisive action.
Here are eight powerful strategies to crush self-doubt, start believing in yourself, and make real progress on your fitness and fat loss journey:
1. Create A Written Plan and Commit 100%
The fitness industry thrives on novelty, and keeping you confused. New diets, workout trends, and “revolutionary” approaches keep you second-guessing your choices. If you’re continually distracted by all these shiny new objects, this will feed your self-doubt.
The solution? Pick ONE solid, proven approach and commit to it completely. Write it down in detail—not just “I’ll work out more,” but specific workouts on specific days, meal plans with macro targets, and recovery protocols, including for sleep hygiene and managing stress.
This written plan becomes your guiding light. When doubt creeps in (and it will), you don’t need to question everything again. You just need to execute the plan you already decided on. This removes the mental burden of constantly reevaluating your approach.
I’ve seen this countless times: the clients who make the most dramatic transformations aren’t the ones with the newest plan or the “perfect” plan—they’re the ones who picked a good enough plan and followed it consistently without constantly second-guessing their choices.

2. Focus on Daily Actions (Process), Not Just End Goals (Outcome)
Goals are vital, including long term goals. And you should dream big. But huge goals like “lose 60 pounds” or “get six-pack abs” can actually feed your self-doubt because the goal seems so far away and so hard.
It’s important to always keep your long-term vision on your mind. But it’s also not only ok to “think small,” it’s essential for breaking through self-doubt, building confidence, and ultimately reaching your big goals.
What I mean is, when you’re goal setting, don’t stop with the big, long term goal. Break it down all the way to daily goals. That’s your plan. That’s also what some people call “the process.” It’s things like: Complete your planned workout. Walk 8,000 to 10,000 steps. Hit your protein target. Drink enough water (not liquid calories). Turn the screens off and get to bed on time.
These daily targets feel believable and achievable. By shifting your attention to process rather than outcome alone, then taking small daily steps, you build belief in yourself. Your identity changes. You start seeing yourself as someone who follows through—which is the true foundation of self-confidence.
3. Collect Small Wins Like They’re Trophies
Self-doubt thrives in the absence of evidence. So your job is to generate overwhelming evidence of your capability through consistent small wins.
In addition to executing your daily plans, set up a series of mini-goals that you can knock down like dominoes. These short-term goals could be daily, weekly or monthly (not long term). They should be slightly challenging, but feel achievable to you. For example:
- Add 5 pounds to your squat
- Hit your step goal 7 days in a row
- Follow your meal plan with 80 – 90% adherence for a week
- Drink 2 to 3 liters of water daily for 10 days straight
- Complete 20 workouts in a month
Each achievement serves as tangible proof that you can trust yourself and your abilities. This creates positive momentum that naturally drowns out the voice of doubt.
Don’t underestimate how powerful setting these small goals can be and how good these small victories can feel. I’ve seen people completely transform their self-image and self-confidence by accumulating dozens of these small wins over time.
To make it more powerful, keep a list or journal of your wins. And to sustain your mental gains, and avoid slipping back into old negative thinking, commit to making this perpetual goal-setting a practice you keep doing for life. Become a goal setter. Make it part of your self image. Not, “I set goals.” But, “I AM a goal setter.”
4. Study Self-Confidence Like It’s Part of Your Training
Most people treat self-confidence as either something you’re born with or something that magically appears only after you’ve achieved your goals. Both of those ideas are dead wrong.
The opposite of self-doubt is self-confidence, and self-confidence is a skill. It’s a skill that can be developed systematically just like any other aspect of fitness.
A book that’s been transformative for many of my clients is “The Confident Mind” by Dr. Nate Zinsser. It’s the same mental performance system he uses with elite military units and Olympic athletes.
His approach treats confidence as a specific capacity you can build through deliberate practice—not a personality trait or a result of success.
5. Create an Environment That Makes Confidence Inevitable
Your environment either reinforces your doubts or challenges them. Be ruthless about curating your surroundings to support your confidence, not erode it.This means:
- Audit your social media feeds—do they make you feel inspired or inadequate?
- Choose podcasts and content that emphasize process and persistence, not overnight transformations.
- Set up your physical space for success—workout gear visible, healthy food accessible, motivational pictures or quotes on the wall.
- Evaluate your social circle—are they supporting your goals or subtly undermining them?
Your brain is constantly scanning for evidence that confirms your existing beliefs. If you believe you’ll fail, you’ll find reasons why that’s true. By deliberately surrounding yourself with evidence of possibility, you begin to rewire this mental filtering system.
6. Embrace The “Good Enough” Plan Instead Of Chasing The “Perfect” Plan
A popular saying is, “perfectionism is just procrastination in disguise.” We could also say, “procrastination is self-doubt in disguise.” The pursuit of the “perfect” workout plan or the “optimal” nutrition strategy keeps you stuck in research mode instead of action mode.
One of my favorite quotes is from General George Patton. He said,
“A good plan executed violently now is better than a perfect plan next week.”
We could also say that a good plan carried out consistently over a long period beats a great plan that’s constantly changed.
When it comes to choosing your plan, make the decision quickly and commit fully. Then save your analytical energy for making adjustments based on real-world results—not speculative possibilities.
Some of my most successful transformation clients started with very basic approaches that they simply executed without questioning for 12 weeks before making any major changes or completely switching routines.
7. Implement a “Doubt Management Protocol”
Self-doubt isn’t something you eliminate once and for all—it’s something you learn to manage effectively. Rather than trying to use positive thinking or willpower alone, rely on a specific protocol for when doubt strikes:
- Acknowledge the feeling without judgment (“I’m experiencing doubt right now”)
- Ask yourself: “Is this doubt based on actual evidence or just fear?”
- Remind yourself of previous successes (keep a physical list)
- Take one immediate action that moves you forward, no matter how small
- Connect with supportive people who reinforce your capability
You’ll never eliminate self-doubt completely, especially if you have big dreams and set big long-term goals. But having a protocol like this ready means you won’t be caught off guard when doubt inevitably surfaces. You’ll have a system to deal with doubtful feelings and move forward despite it.
8. Use External Accountability Strategically
Sometimes the best way to overcome self-doubt is to make yourself accountable in a way that makes following through easier than backing out.
This could mean:
- Hiring a coach who expects weekly check-ins
- Finding a workout partner who counts on you showing up
- Joining a group challenge (like our Burn the Fat transformation contest)
- Scheduling workouts as non-negotiable calendar appointments
- Making a public commitment to a specific goal with a timeline
- Joining a support community (like our Burn the Fat Inner Circle)
Ultimately, you must be accountable to yourself first. But external accountability creates boundaries around your tendency to overthink and question yourself. It provides scaffolding while you gradually build up your internal confidence systems.
The Truth About Self-Doubt
Here’s something most fitness coaches won’t tell you: Even the most confident-looking, successful people in fitness deal with self-doubt. The difference isn’t that they don’t have doubts—it’s that they’ve developed systems to act despite those doubts.
Self-doubt isn’t eliminated through positive thinking alone. It’s overcome through positive action that generates real results. Each week you follow your plan builds evidence that you can believe in yourself. Each workout you complete proves you have discipline. Each healthy meal you prepare and eat demonstrates your commitment.
Eventually, these accumulated actions speak louder than the voice of doubt in your head. Remember, you don’t become confident and then take action—you take action consistently until confidence becomes the only logical conclusion based on your track record.
The path to your fitness goals isn’t about finding some magical approach that eliminates all doubt. It’s about acknowledging your doubts, creating systems to manage them, and moving forward anyway—one workout, one meal, and one day at a time.
Stop waiting for the doubt to disappear before you start. Keep thinking big and long term. But also think small, start now, and watch how your simple daily actions gradually transform not just your body, but your fundamental belief in what you’re capable of achieving.
