About
***While I predominantly run my training from my gym in Westlake village, I can offer a few options to have one of my experienced trainers come to you. You’ll enjoy a tailored workout in the comfort of your own home for an additional fee.***
My company has trained over 500 people to help them move better, feel better, and become a more fit and healthy version of themselves.
We specialize in:
Mobility/ pain rehabilitation
Weight loss and muscle gain
Fitness nutrition
Sports specific training
What makes us different then other trainers:
1. Phasing your workout program: One size does not fit all when it comes to training. Our program will be customized to fit you and will constantly be changing so that you don’t plateau and slow your progress.
2. Pain management and posture training: Part of our program will learn to understand what pains you go through in daily life and on the first day training with us you will learn how to begin alleviating those pains. You will also begin standing up more straight and moving how you were intended to move.
3. Eating to optimize your fitness journey: What you put in your body is just as important with how you are exercising. Along the way of your training you will learn what you need to be fueling your body with so that your results come faster then expected.
About me:
I have been personal training since I was 21. I have been in the field of fitness all my life. Participating in all types of sports including baseball, basketball, football, and wrestling. I am also certified as a fitness nutrition specialist and corrective exercise specialist. My sessions generally consist of a 5-10 minute warm up, a 45-50 minute workout, and a 5-10 minute corrective exercise routine or cool down. I include a personalized meal plan as well as workouts to be used when train on your own. I have had many different clients, aging from 18-82, all with different types of goals and would love to help you reach yours.

I needed someone to assist in healing injuries, increasing mobility, and building strength and muscle. Justin gets the job done. He is incredibly smart, educated, and dedicated to this work. He is motivating, patient, and really works toward helping people meet the goals they set out to reach. I showed up having been away from exercise for quite some time, no longer feeling like a version of myself I once liked, and ultimately scared of being judged. Justin is non judgmental and supportive while remaining firm and dedicated to meeting your needs. Best decision I ever made.

Working with Justin has been a game-changer. Over the past couple months, working with him through two 10-session packages, he’s completely transformed how I approach fitness. He’s incredibly knowledgeable, professional, and one of the most in-shape people I’ve ever met - no shortcuts, just hard work and a balanced, natural approach. If you’re serious about fitness, this is the guy to go to.

I’ve been working with Justin for a couple months now and really enjoy our sessions and the customized format based on my goals. He keeps you motivated and gives helpful guidance on other things like nutrition too. Highly recommend hiring Justin as a personaltrainer!

I’ve been truly impressed with Justin. He is the epitome of professionalism—extremely knowledgeable, attentive to every detail, and always taking the time to explain each exercise and ensure proper form and technique. What amazes me most is that I’ve been working out in gyms for many years, yet he continues to introduce me to exercises and techniques I’ve never seen before. His depth of knowledge and attention to detail truly set him apart. I look forward to every session as I see tangible improvements. A++++

Working out with Justin has been a life changing experience! Not only do I feel stronger and healthier, but I also have much less pain than before i started my sessions. He is smart, kind, easy going (but also pushes you to do your best). A true professional all around, 5 stars hands down.

FAQs
What is your typical process for working with a new customer?
During my first session I want to learn about my clients goals and previous injuries. I also try to find out what the client likes and doesn’t like in terms of exercise, if you are not having fun you are not gonna stick with it, and fitness is a lifestyle, nobody achieves results overnight. Then I run a couple of fitness assessments to see where the client is currently at in terms of fitness. Then after a quick workout I will talk about nutrition and a game plan for the month. The first 30 day are crucial and will truly determine your success.
What education and/or training do you have that relates to your work?
I am NASM certified and working on my nutrition certification and my performance enhancement certification. I have been in sports all my life. Fitness and strength training is my passion, and I love helping people achieve there best selves.
What types of customers have you worked with?
I have worked with all types of clients but specialize in athletes, kids, and people looking to lose weight.
