    Frequently asked questions

    Here you can find answers on frequently asked questions. If you cannot
    find the answer, feel free to contact us via email or phone.

    What makes your training approach different?

    I focus on sustainable lifestyle changes rather than quick fixes. My program combines evidence-based exercise science with behavioral psychology to help you build lasting habits. Each client receives a customized plan that considers their unique goals, limitations, and lifestyle factors.

    Do I need to have previous gym experience?

    Not at all. My training programs are customized to your current fitness level. Whether you’re completely new to exercise or an experienced athlete, we’ll create a plan that challenges and develops you appropriately.

    How quickly will I see results?

    Most clients notice initial improvements in energy and strength within 2-3 weeks. Physical changes typically become visible around the 6-8 week mark with consistent training and proper nutrition. Remember, sustainable results take time – we’re building a foundation for lasting change.

    What my clients have to say

    “Working with Jackson for just three months has been a game-changer! My deadlift, bench, and squat have all increased by 20%. I am the strongest I’ve ever been at 44. His personalized approach and expert guidance make every session productive and motivating. If you’re serious about reaching your strength goals, Jackson will get you there!”
    Ryan Kelly, 44
    "If you’re looking for someone, who’s very knowledgeable, patient, lighthearted, fun, but very professional Jackson is your kind of trainer. He works with all different ages and skill levels. He helped me achieve so many of my goals plus introduced me to some new skills and really started my new journey on learning how the body works in at a deeper level . Even gave me some introduction lessons to boxing for cardio needs. He keeps things interesting and changes it up especially if you need to keep it fun and engaging. "

    "Working with Jackson for the past three years has completely transformed my fitness journey. When I first started, I had little to no knowledge about weightlifting or how nutrition fueled my body. Jackson has been an incredible coach, combining deep knowledge of muscle groups with a keen understanding of my body, age, and metabolism. He designed a personalized 1:1 plan with daily workouts and a full nutrition strategy, and I’ve seen amazing results.

    I’ve gotten stronger, leaner, and more energized—and the best part is that I’ve gained so much confidence, not just in the gym but in how I feel about my body and even in my clothing. Upper body work, which I used to avoid, has become one of my favorites, especially as I see progress in my back and shoulders.

    Jackson has always been patient and supportive, teaching me without ever making me feel incompetent. His ability to explain complex concepts and guide me through exercises has helped me grow into a more capable and confident version of myself. I am beyond grateful for the progress I’ve made with Jackson’s guidance and would highly recommend him to anyone, regardless of age or fitness level."
