About

1:1 Personal & Strength Training in Kailua Hi, I’m Gen 👋 I’m a personal trainer and strength coach offering private, one-on-one training at Elevate, a welcoming boutique fitness studio in Kailua. No separate gym membership is required to train with me. Your first session with me is complimentary. It gives us a chance to meet, talk about your goals, move together, and make sure we’re a good fit before you commit to anything. Your first session with me is complimentary. It gives us a chance to meet, talk about your goals, move together, and make sure we’re a good fit before you commit to anything. My coaching style is encouraging, intentional, and built around consistency — not quick fixes. I work best with clients who are ready to show up for themselves and want a coach who’s genuinely invested in their progress. Every program is customized, structured, and designed around you — your goals, experience level, and lifestyle. My approach blends strength training, functional movement, kettlebell work informed by StrongFirst principles, and TRX training for stability and full-body strength. A big part of my coaching is developing a strong mind-to-muscle connection — learning how to move with intention, understand what you should be feeling, and get more out of every exercise. I want you to understand the *why* behind what we’re doing so you can build confidence in your body and in the gym. I believe training is one of the most valuable investments you can make in yourself — in your health, strength, confidence, and overall quality of life. Real results come from treating fitness as a process and showing up consistently over time. My role is to guide, support, and challenge you along the way. If you’re looking for a supportive, knowledgeable coach who will meet you where you’re at and help you become stronger and more confident, I’d love to connect and see if we’re a good fit. 💪

Gen helped me get much stronger! When I started training with her, I was experiencing some pain with squatting at relatively low weights. She assessed my strength and form, then we got to work. Our workouts were a good level of challenge and a mix of old and new exercises. For all of the exercises, she helped me understand the proper form and how to ensure I worked the right muscles. Gen made training very approachable and I had a lot of fun! I'm really grateful I trained with Gen, she helped me develop balanced strength and a great foundation for my strength training.

I can’t say enough good things about Coach Gen. She is incredibly encouraging, patient, and genuinely invested in her clients. I started out feeling really unconfident and unsure of myself, and she helped me get to a place where I actually believe I can reach the goals we set together. What I appreciate most is how supportive and approachable she makes everything feel. Nothing ever feels overly intimidating or discouraging. Honestly, just knowing myself, I don’t think I’d still have a gym membership if it weren’t for her, because I probably would’ve quit by now out of sheer lack of motivation and accountability. She’s made such a huge difference for me, both physically and mentally, and I’m so grateful to be training with her.

When I began working with Coach Gen I told her, “My only goal is to feel strong.” However, Coach Gen gave me so much more than that. Today, I feel confident walking into the gym by myself. I have knowledge on how to make myself stronger. I have a changed mindset on my relationship with working out and nutrition. Coach Gen, has changed my life. I am strong now because of her.

I’ve been training with Gen since March, and the progress I’ve made under her guidance has been incredible. She’s helped me reach personal strength goals I never thought possible, and I’ve seen real changes not just in my body but in my overall well-being. My muscle tone has improved noticeably, and I feel more confident in my body than ever before. Beyond the physical results, Gen has made a huge difference in my mental health and energy levels — even my chronic fatigue has improved since working with her. She’s encouraging, empathetic, and genuinely cares about every client’s success. She knows when to push you and when to meet you where you are, which makes every workout both challenging and achievable. Gen truly goes above and beyond. She celebrates your wins, checks in when you need support, and empowers you to show up for yourself in ways that carry over far beyond the gym. Training with her has been one of the best decisions I’ve made for my health, physically, mentally, and emotionally. I truly adore her.

FAQs

What should the customer know about your pricing (e.g., discounts, fees)?
Training options are available based on how often you’d like to meet, including single sessions and recurring monthly training. My first session is complimentary so we can meet, talk about your goals, move together, and make sure we’re a good fit before you commit. From there, I’ll help you choose the option that makes the most sense for your goals, schedule, and desired training frequency.
What is your typical process for working with a new customer?
Your first session with me is complimentary. We’ll start by talking about your goals, training history, lifestyle, and any injuries or limitations I should be aware of. From there, we’ll move through some exercises together so I can get a feel for how you move, your current strength level, and where we may want to focus. It’s also a chance for you to experience my coaching style and see if we’re a good fit. If you’d like to continue, I’ll build your training around your individual needs and goals, with an emphasis on proper technique, mind-to-muscle connection, consistency, and progressive strength.
What education and/or training do you have that relates to your work?
I’m a NASM-Certified Personal Trainer, StrongFirst-trained kettlebell and strength coach, TRX Certified, and a UFC Gym Certified Coach. My background is rooted in strength training, functional movement, and safe, effective programming that supports long-term progress.
