Introduction: Are you tired of spinning your wheels at the gym, seeing mediocre results? Have you tried multiple diets - Paleo, Atkins, Vegan, Keto - and had mild success only to regain the weight? You don't need a trainer, you need someone to help you cut through the noise and deliver results. I'm not here to berate you for your failures, or scream at you to work harder. I'm here to help you make small changes that you can stick to, to change your life for the better. We'll use science-backed methods, both in the the gym and in your regular life, to make fitness easier. Starting on a journey to better health can be hard, but we can break it down into little, easy-to-handle habits that yield amazing results over time. We'll also develop a plan together to get you exercising as often as you need to. Contrary to popular belief, most people don't need to be in the gym six times a week for 90 minutes at a time. The most important part is showing up, so we'll plan sessions that fit into your schedule, no matter how busy you are. I don't require any contracts or upfront package purchases, so if your schedule changes we can reorganize at any time. You'll be training at my private, boutique-style personal training facility that is 100% free of the 'corporate gym' nonsense. There are no memberships or fees besides what you pay me, and I have access to TWO state-of-the-art facilities. One is in Mission Bay on Morena Boulevard and the other is in La Mesa, near Grossmont Center. We're also taking COVID seriously, and strictly enforcing masking and social distancing protocols. If you have any questions about this, I'm happy to answer them, but I can just about guarantee this is the safest gym experience you can find during the pandemic. My Specialties: Some of my clients want to lose weight. Some want to put on muscle. Others have specific athletic goals in mind. The common denominator is building functional strength and the confidence to use your body for the tasks you need it. My expertise is in building strength specific to YOUR needs. I'm not a bodybuilding coach, and strength doesn't always mean increased size. Instead, think of an athlete's body, primed to do its job to the best of its ability. Whatever your requirements of your body, functional strength, stability, and confidence are imperative, and that's what I specialize in. I've personally lost over 50lbs since my heaviest. It took me about six years to lose the first 20, struggling with various diets and roadblocks along the way. In the last couple years though, I spent time learning the science of fitness, as well as the psychology of behavior change. I can tell you from personal experience that I understand how confusing the industry can be. I want to make it simpler and easier for you than it was for me, and teach you the skills you need to stay in shape for the long term. Discounts: The pandemic has definitely affected my business, so I'm offering deals for the first 4 clients signed up in 2021! The rate you sign up at will never change, so sign up now to lock in your lower rate! Take control of your life, make some small changes, and you'll be amazed at how good you look and feel. Contact me today. If you take the first step, you'll have a partner for the entire rest of the way!

I had fallen off track and been a slob for quite some time. Working with Grant made getting back on the rails easy and made me feel confident about reaching my fitness goals. I recommend him for anyone and everyone in search of a trainer.

I’ll drag myself to the gym after a full day of work and errands. Grant always greets me with a smile. About 10 minutes into the session I’m also smiling. I’m having fun and the tensions of the day slide right off. I’ve done the serious work outs with the serious trainers. Never again. A tight butt that comes with a good laugh is wayyyy better. Thanks Grant!

Working with Grant has been great! After playing a sport in college I never thought I’d enjoy lifting the same way, but Grant has made it fun, challenging, and something I look forward to every morning. In just a few months, I’ve even been able to things I couldn’t do when I was playing.

Grant does a great job of providing complete workouts that can be done by anyone, no matter the fitness level or life schedule. He is very responsive when I have questions and checks in regularly on both my workouts and my nutrition.

  • What should the customer know about your pricing (e.g., discounts, fees)?

    My pricing is dependent on my clients' needs. Most of my clients are on monthly plans for a given number of sessions per week, and sessions start at $30. Partner sessions (you and a friend, spouse, teammate or colleague) start as low as $20 per person per session and are a great way to get an affordable plan that’s customized to you! There will never be any additional fees besides what you pay me for training!

  • What is your typical process for working with a new customer?

    I offer a no-obligation complimentary session and consultation, in which the customer and I determine what they need and if we're a good fit. From there, we work together on a comprehensive diet, exercise, and lifestyle plan to get the client to their own specific goals. No two of my clients are the same.

  • What education and/or training do you have that relates to your work?

    I am a Certified Strength and Conditioning Specialist (CSCS), through the National Strength and Conditioning Association (NSCA). The CSCS is the same certification held by most Strength and Conditioning Coaches at the Collegiate and professional level. The NSCA is accredited through the National Commission for Certifying Agencies, a governing body considered the gold standard for certifications in the USA.
