    Get Results—Or Your Money Back

    At Green Door Fitness, we don't just help you lose weight—we help you transform your life. Our 28-Day Personal Training Pass is designed to get you results, guaranteed. Do the plan, see results, or your money back. No other Denver gym makes this promise.

    Who Our Weight Loss Program Is For

    • People who've tried other programs and didn't get lasting results

    • Those with 10-100+ pounds to lose—we work with all starting points
    • Anyone tired of yo-yo dieting who wants sustainable habits
    • People who want accountability without judgment or pressure

    Why Our Approach Works When Others Haven't

    Most weight loss programs fail for two reasons: lack of accountability and unsustainable methods. We solve both:

    • Coach on floor every visit: You can't skip when someone's expecting you
    • Strength training focus: Build muscle to boost metabolism long-term, not just cardio
    • Real food, not fad diets: Sustainable nutrition guidance you can maintain for life
    • Progress tracking: Weekly check-ins to adjust your plan based on results
    • Money-back guarantee: We're so confident, we put our money where our mouth is

    2. Day-1 Assessment – Meet your coach, take baseline measurements, establish your custom plan
    3. Train 3-5x/Week – Come in when it works for you; a coach is always on the floor
    4. Weekly Check-ins – Review progress, adjust nutrition, troubleshoot challenges
    5. 28-Day Evaluation – Celebrate your wins and plan your continued journey

    Realistic Results Timeline

    • Week 1: Establish routine, learn proper form, initial energy boost
    • Week 2-3: Clothes fit differently, improved sleep, reduced cravings
