Testimonials

" Larry is great. He works with you so your goals are manageable and you see results. He's not the type of trainer that barks orders at you, but he also not the type that goes easy on you. It's a good combination and I highly recommend him! "

" Best trainer ever!! I owe all of my ACL surgery recovery to her. Brittney got me in even better shape then I was before and managed to regain all the muscle in my leg in just 6 months of recovery time. She provided me with all of the knowledge, work outs, and dieting I needed for the best results. It is hard to find trainers who truly care about her clients like she does. "

 

" Larry Cook is the best there is! I have been competitively bodybuilding for the past 2 years. I have worked with two other personal trainers to help me reach my weight loss and muscle gain goals. But it is really in the past 7 months working with Larry that i have learned the most about muscle gain and fat loss. When it comes to Nutrition i do not know someone who is more knowledgeable then Larry. I have surpassed all the goals i set for myself under his training. If you'd like to reach that weight loss or muscle gain goal you set for yourself Larry is the man that can really show you the way. "

 

" I love Brittney's motto "please don't Photoshop me"! She's very REAL and will help you get real results all while understanding your human flaws. No one is perfect, she works with you where you are right now and helps you get better! She is an expert in multiple areas (personal training, fitness, diet/overall wellness) so she can customize a program that will work for you! "

" I've been training with Larry for a little over a year now. When I started I was around 18% body fat. Had quite a large belly, no abs, no arms, and no chest. 6 months into my program, I was 6.93% body fat with a killer 6 pack, chest, arms, and a great back! Larry has always made me feel as if I was his only client. He never rushed my sessions and always stayed on top of my progress. I've had several trainers in the past, but without the results. Larry is by far, the best and most knowledgeable trainer Ive ever used. He also is very knowledgeable on the proper ways to diet which is a key factor in changing your physique. Thank you Larry for changing my body and my life. "

She helped me lose the weight because I really needed to gain back some confidence! She knew exactly what to say and do to help me in my weight loss journey. She is very professional, educated, and passionate with her work. I'm a very happy client, and will continue with her services. 30 lbs down and counting!! "

" Larry rocks! He transformed my Dad-Bod in only 2 months, and got me back to my College body in that short period of time. Hes a great trainer in, and out of the gym. He actually sincerely cares about you, and focuses on your individual goals. He's taught me so much about exercise, but he's also schooled me about overall health, diet, nutrition, etc. I can honestly say he's taught me things that will be beneficial to me and my health, for the rest of my life. Im looking forward to continue to train with him in the near future, and recommend him to anyone looking to get rid of their dad-bods! (or mom-bods.) "

" I’ve been working with Brittney for the past few months and it has been the most powerful, liberating, transformative time period of my entire life. I can honestly say she is the best personal trainer. I’ve struggled with weight issues since I was a child; at my heaviest I was 180 lbs during my adolescent years, and eventually got to my thinnest at 130 lbs as a teen while using unnatural medications such as phentermine. This pattern of yo-yo dieting followed me throughout high school and college, and has since been the cause of much frustration and confusion about my body; I had no idea how to eat healthy or figure out what makes my body function optimally. I also was never really a fan of intense exercise. Brittney has helped me with all of this. I came to her at 148 lbs and she has helped me lose over 20 lbs (and counting) over the course of 5 months and keep it off (which in my opinion, is the hardest part). She has not only helped me to reach all of my personal fitness goals, including building a nice butt and building the stamina to be able to run on hikes, (and made it super fun while doing so), but also has inspired me to create new goals constantly. I now plan on training for a triathlon in the near future. And all of this is just the physical aspect of her training. Brittney knows SO MUCH about food and nutrition, which has always been my downfall. As I mentioned, I have always struggled with this, so being able to have someone to guide and teach me about my individual dietary needs has been so incredible and extremely beneficial. I now know what foods my body thrives on, and which ones it does not need. I now have the knowledge to be able to lose or maintain weight for the rest of my life, and that is priceless. Brittney is so good at what she does, and there’s a reason for that–passion. She is super passionate about her work and her clients. You can tell that everything she does, she does with so much fire; you can’t help but feel that way too whenever you’re around her. She goes above and beyond the typical “trainer”, as well. She has taken a range of science-based nutrition classes at UCLA in addition to her multiple certifications for personal training. She is more than a trainer– she is a mentor, a life coach, a wonderful, amazing friend who needs to be in your life. And while I've learned so much about fitness and nutrition, reached and broke through my goal weight, gained muscle and curves (in all the right places) through Brittney, the most invaluable thing I’ve learned from her is the importance of inner strength. She has helped me to cultivate an inner power and confidence without even realizing it. Every session empowered me and inspired me to be better in all aspects of my life. This has been the best investment I've ever made, hands down. There is nothing more important in life than being healthy and happy, and Brittney has allowed me to achieve this. If I hadn't chosen to go into the medical field for my career, I probably would've followed in Brittney's footsteps into the realm of fitness and nutrition. Basically, Brittney has changed my life in more ways than I can count and I can’t thank her enough. "

"I got to a point in my life where I needed to change the way I looked and felt. Even though I had worked with various trainers over the years (with mixed results) I really wanted an instructor who motivated me to do well, cared about my progress and kept me interested every session. Hands down, Larry Cook is that trainer. Larry made me accountable for my diet, designed a weight training program for my specific needs and made reaching my goal(s) fun. When my wife, family and friends compliment the "new me" it's a wonderful feeling, and it validates who Larry is as a trainer. He is simply the best."

" Meeting Brittney and having her as my personal trainer was the best decision I had ever made and it changed my life! In February 2016 I was 37, weighed 410 pounds and was diagnosed with diabetes, sleep apnea, and edema in the legs. I had lower back pain for some time and couldn't stand past 30 minutes and had other complications that come with being very overweight and unhealthy. I would run out of breath each time I walked up 2 flights of stairs to get to my condo and I'd carry a handkerchief all the time as I would sweat everywhere I went. I didn't have any energy and was always tired, too tired to play with my 4 and 6 year olds and to take them out. My comfort zone was eating junk food, my couch and my TV. My shirts were 4XL and pants were a size 48 but I'm sure I was a size 50 as it got to the point where I had to unbotton them and rely on my belt to hold them up. On flights I was too big to fit in a coach seat so I'd get first class and request a seat belt extension. At this time, my Dr. had told me if I changed my lifestyle with proper nutrition and exercise, I could reverse my diabetes and sleep well without the use of machines, the CPAP machine was uncomfortable and intolerable and didn't help me sleep any better on the first and only night that I tried it. I decided I needed help from a personal trainer. I met with Brittney and I was so impressed by how knowledgeable she was in both fitness and nutrition and how she understood my situation. She explained what we would be doing and why and she would provide meal plans to follow that were connected to the workouts we would be doing. We started training right away and to this day we have not stopped nor do I ever plan on stopping! Thanks to Brittney, I've lost 170 pounds in a year and now weigh 240 pounds. At 38, I'm 100% diabetes free and off meds, sleep apnea is gone and I can fly coach without the need of a seat belt extension! My shirts are L, pants are down to size 36 and we are still going! Lower back pain and complications are all gone and I'm the healthiest I've ever been. Getting tired climbing stairs is a thing of the past now and never thought I would love running and doing cardio. We are still constantly getting amazing gains and results. We are overcoming goals and setting new goals and I couldn't be happier! Brittney is just an amazing person and great to work with. There's no such thing as routine with her. She's always changing it up, raising the intensity and pushing. She's always teaching and reminding how to do movements and lift weights the right way so you don't hurt yourself but most importantly, so you get the best results out of them and it just blows me away! The meals themselves are so delicious and she was constantly changing them so I could try new foods and get ideas myself. She also recommended the proper vitamins and supplementation that are fantastic. She tracks everything from the workouts, nutrition, amount of weights, sets, reps you name it and she always has a plan ready for the next session. The most important thing about Brittney is she cares, she doesn't stop after the session is over. She checks in to see how you're doing and feeling and makes recommendations. She changed my life and I'm forever grateful! Thanks Brittney!! "

" This is hands down the best experience I've had with a trainer. Unlike other trainers, Larry made sure I got results. He made sure I ate the right foods, got the right supplements and was on top of me with my weight. He's a really humble and sweet guy and is extremely easy to bond with. He will not only challenge your body but he'll find some way to make it fun. Training with Larry will guarantee results! "

I have been working with Brittney now for 6 months and my results are amazing. Because of my poor physical condition when we started (I hadn't worked out in over 10 years, had 2 c-sections, "bad knees"), she had to take me way back to the basics. I had no muscle, no stamina and no energy. Now, I am doing things I have not been able to do in about a decade, like play on the floor with my kids....and get up without someone's help! I sleep SOOO much better at night and I actually have energy to work out these days. 
What I love about working with Brittney, besides her "pleasant persistence", is the way she can tweak a work out depending on what you are feeling: "Brittney, when I do that I feel slight pressure on my knees" "OK, turn your heels out and lean forward a bit more"....pressure gone and workout continues! I could not have achieved so much in such a short time without her!

I am now a much healthier person thanks to Brittney. She is making sure I am going to be around much longer for my kids and family. THANK YOU Brittney! "

" I highly reccomend Larry Cook as a personal trainer. I'm a professional dancer, choreographer and fitness instructor and wanted to tone my body up and loose fat. I wanted a new image and wanted to increase my chances of getting callbacks at auditions. I have a very busy schedule and I'm tired the majority of the time. Therefore, I knew I wouldn't go to the gym and eat right if I didn't have someone who would hold me accountable for my eating habits and push me to workout (especially when I'd rather sleep in on an early morning!). Thus, with this motivation in mind I started my search for a personal trainer. My first step in finding a personal trainer was "googling," personal trainers in Woodland Hills. Lo be hold he came up highly reccomended. I called him, had a meeting, started his program and lost 39 pounds with his guidance and encouragement. It was an amazing experience and helped me not just loose weight but also learn about nutrition. It's been a lifestyle change and I've been able to continue with the structure he introduced me to in regards to cardio, weight lifting and healthy eating. It's been a great journey and I reccomend him to anyone who has similar fitness goals or works in the arts! "

Why TRIANGLE THEORY Training?

Intensity. Variety. Consistency.

With an equilateral triangle, one side cannot exist without the other or the structure collapses.

Show More

By implementing our three essential elements of intensity, variety and consistency we give our clients the tools they need to overcome road blocks so they can achieve personal success. As mentioned, results from other personal trainers are often “quick fixes” - short term changes in one’s physical appearance. However, over time, a person’s mind and body disengages from a monotonous regimen because there is a lack of growth, physically and mentally. Simply stated, men and woman who see diminishing returns after working out for a long period of time will likely quit due to emotional distress from doubt or boredom. However, with the Triangle Theory Training program, Larry and Brittany will revitalize you and your approach to working out. With their guidance, each client will embrace a system of intensity, variety and consistency that will help them achieve their desired goals. If you’re ready to positively transform your life, overcome obstacles and realize your goals, then Triangle Theory Training is for you.
