About
With 10 years of experience as personal trainer, I know what it's like as an individual to overcome adversity. I started my fitness journey at 235 lbs and since then have been able to accomplish losing over 80 pounds with intended plans of stepping on stage in the bodybuilding world to compete in women's physique. Since starting I fell in love with the process and set out with a purpose to teach individuals that it's not just a diet or quick change it is a process, mindset, and lifestyle change change that helps to develop you into a better individual in different aspects of life not just the gym. And most importantly if i can do it, anyone can! Let me help you make it happen:)!

What I really appreciate about Karlyn is that she not only understands traditional lifting techniques, but also has an incredibly detailed understanding of body mechanics. She pays attention to things a lot of trainers overlook, like smaller muscle groups and joint health. That makes her uniquely suited to help whether you’re trying to get stronger in general or recovering from an injury. Having someone who understands the ins and outs of training the way Karlyn does is critical for training safely. I can't recommend her enough!

I have been working with Lasko Fitness well over a year now, and she is great to work with. She has helped me see a difference in my body, as well as helping with my confidence as well. She is an amazing person you can talk about with anything, whether it has to do with training, life problems, or even boy issues haha. I would definitely recommend her as a trainer, and it’s been great working with her!

I started working with Karlyn in February of this year and there are many things I can highlight as a coach. I had been working with an online coach for a year and a half and decided I wanted a change. I could feel that I was doing exercises wrong and I was getting frustrated because of it. I wanted to find someone that I could work with in-person. Enter Karlyn 😊
One thing that Karlyn does that I absolutely love is Mobility. She has a rule of starting every workout with mobility. Whether you are training with her or online. And I love that they are different week to week. Mobility has helped me get the most out of each and every session. Second thing: She cleaned up my squat, bench, and deadlift form (form is very important to her lol). Helping me understand what is comfortable and get the most out of my body. Third thing: She helped me define my weaknesses and came up with a plan to attack them. My outer glutes and extremely week and my adductors are short. We’ve focused specifically on those and worked on lessening my internal rotation. Fourth thing: I’ve never been able to do a pull-up by myself. She helped me learn how to do them (it truly is a process). I could keep going on and on.
Karlyn is knowledgeable, kind, and will help you get the most out of your training. Working with Karlyn has been one of the greatest decisions I’ve made and it will be your greatest decision as well!

I started working with Karlyn online about one year ago. I came to her with an L4/L5 disc herniation that had occurred 2 years prior. Over those 2 years, I lived with daily back pain and frequent, extended flareups. I chose to work with Karlyn for her approach integrating prehab/rehab into her programming. My goals when we first started working together were to get my back to a better place and to build muscle/strength. I have been impressed with Karlyn’s ability to spot form flaws in my check-in videos and provide cues to fix these issues. Over the course of the last year, my daily back pain has nearly disappeared and flareups are rare. When flareups occur now, they dissipate within days as opposed to weeks. I have also put on substantial muscle and built nice definition. Karlyn listened to my concerns and delivered results. All while working remotely. Karlyn is a very knowledgeable coach and I highly recommend working with her.

Karlynn is such a great trainer. She listens to your goals and works hard to help you achieve them. Her program is tailored to the clients needs and she is a great positive motivator. Getting to go see her at the gym and work towards my goals at the same time is the best part of my day. She has such an uplifting fun spirit and I can't imagine training with anyone else after meeting her!

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
I offer a free consultation session to best help you make your decision. This consultation is where I will take you through a typical training session for you to get a feel for my training style. We will also see where you're at physically and be able to talk about your goals and needs. I have several packages I offer and would like to think there's a package to fit everyone's needs as I'm competitive with the current market pricing.
What is your typical process for working with a new customer?
It's always a blessing when people want to get in the best shape of their lives. It's exciting! And with that It is important to me that I am a good match for you otherwise that cannot be achieved . I prefer to have an in person consultation before a decision is made on using my services to see if we are the right fit, I don't want to waste your time or mine. Once it is a match I ask for my clients to fill out a questionaire form to better create a customized plan for your fitness goals. From there on out.....THE FUN BEGINS:)!
What education and/or training do you have that relates to your work?
I am NASM certified and also have a background in power lifting, I truly believe this is the best method anyone ever taught me for learning proper form on core lifts and I utilize it to also proper form to my clients. I do not claim to be a power lifter or set up programs that are power lifting specific however if you want a trainer who will help you improve your lifts along with injury prevention through execution of proper form I am fully capable of doing that for you!
