I've always done high-intensity workouts, so I was curious about Jake's targeted approach when it comes to lifting. His programming really works the smaller, often neglected muscles, and I can already see and feel the difference. I've even had friends notice that I look leaner and more defined, which is always a bonus!! If you're looking for a program that delivers real results as well as nutrition advice on a budget, I highly recommend signing up! read more

Jake did an exceptional job. He was very thorough, detail-oriented, and genuinely cared about my progress. What stood out most was how well he listened -- especially when I explained the struggles I was having with my meal plan and training program. He adjusted things to fit my needs and made sure I understood the "why" behind everything. I've made real progress thanks to his guidance, and I highly recommend him to anyone serious about improving their health and fitness. read more

With his expertise and consistent training methods, Jake will guide you on a path to a better version of yourself

I had been training on my own for a while but felt like there was something missing. I've been working with him for three/four weeks now and have seen an insane improvement in muscle tone and fat loss. Super nice, willing to work with your particular goals, body needs and really teaches you the right form so get maximized results fast. Your body will thank you. read more

I mentioned to Jake that I injured my shoulder years ago lifting. The pain has bothered me off and on for years. My shoulder was inflamed and had been hurting me for over four months. He quickly analyzed the problem by observing my posture and testing my flexibility. I was given very specific exercises along with posture improvement keys. I saw immediate results. My shoulder was much better within a few days. As a bonus, the improved posture has helped ease my lower back pain, increased my flexibility, and improved my overall health. Jake's training sessions are game changing. read more

I tried doing the whole weight loss thing on my own. I did my research and did different things which didn't work. I finally decided to get a trainer. I just needed someone who knew the ins and outs of getting there body into shape. I went only and looked for a trainer. I had different trainers calling me left and right trying to get me to train with them. It felt like they were trying too hard. As I searched I found Jakes site. I saw his profile and before after picture. His before was exactly how my body was when I started. I got in touch and he was quick to respond. I told him I was looking to drop the weight that I gained. I started at 186. With his regiment he gave me which included a strict meal plan and a minimal workout plan I was able to drop down to 165. This time frame was from the last week of November 2023 to the 3rd week of January 2024. I found my bodies cravings have disappeared. It really was sticking to his process but I didn't expect such results. He has good knowledge and a great website to follow workouts on. I will recommend him to anyone who doesn't know where to start. Thank you Jake! read more

Among all the trainers I've worked with, Jake is the best. He's professional, very knowledgable and does a great job motivating you. His integrated approach of fitness and nutrition helps you stay on track for your goals throughout the week. What's best about his sessions is that the focus on form, combined with motivating you to push yourself for a the extra few reps has helped me gain strength faster than I ever have before. As someone who has always preferred cardio over weights, Jake has really made strength training something I look forward to each day. read more

I've been working out with Jake for 5 weeks now and have really enjoyed the journey so far. Jake is always on time, super personable, and makes working out way less of a grind. He focuses on form over just piling weights on and is great when it comes to pushing an extra few reps out of you. He is also committed to making sure your diet is on point as well - one time he even texted me randomly one night as I was reaching for some cookies - dude has a fitness 6th sense I think. So far it's been a great experience, definitely give Jake a call if you're trying to get in shape! read more

We love working out with Jake! My boyfriend and I first started working out with him when we moved to LA. He's always really professional & cares a lot about his clients. Definitely recommended! read more

I reached out and received a quick call back and scheduled an appointment. He showed up on time and prepared. I was impressed with his direct approach, knowledge and organization. He also makes an effort to make you feel comfortable right away and is easy to speak with during the workout. He knows just how far to push you without stressing you out. He focused on what goals that I wanted to accomplish and provided a workout customized to those requests. He provided tools to help with those goals and sent my workout to me afterwards to use on my own. I would definitely recommend. read more

I started training with Jake on 3/22/18. My goal: gain muscle and lose some body fat... a tall order! I knew it would be really tough since I'm 50 and yep, menopausal. I'm not a scale person but I probably needed to lose 7-10 lbs. I tried doing it on my own by cutting calories & doing extra cardio - NO changes. I tried South Beach... lost 1 pound in 3 weeks while the husband lost 7. Grrrr RESULTS SO FAR: After 1 month of training with Jake, I've lost a total of 7 INCHES (upper & lower abdomen, thighs, etc.)!! I lost a few pounds too. I would've lost more scale weight but I gained valuable muscle. We have 2 more sessions to go, so I'm expect that a few more inches will vanish. SO SO HAPPY!! I've gone down almost 2 belt notches, my puffy stomach is finally flattening, my thighs are SO tight and my arms are finally showing real muscle tone. :)) ROUTINE: We trained 2x/week, and Jake advised me to do cardio 3x/week (30-45 min. power walking plus 10 minutes of treadmill HIITs). It's tough but it's worth every second and every penny! Jake makes it fun... as fun as pain can be. :)) He pushes hard but also understands client limitations (I have a lower back issue). I've worked with a few other trainers years ago and he is by far THE BEST!!! He got me "beach-ready" for a very special anniversary trip to Fiji. THRILLED! read more

I've usually been successful with Yelp and on this occasion was disappointed. I had an accident and was hoping to hire a trainer who understood recovery and the body. Jake is a nice guy however with a back injury and concussion Jake had no idea how to take baby steps. If you are looking for muscle and weights he is the guy. If you are into stretching, toning, and a trainer who understands recovery, this is not your guy. My back got worse after working out with him. Hate to write this but hope the next person has a better understanding of his limitations and strengths. read more

Although I was often late for our work-outs, Jake was always on time and pumped to get my work out on! He's someone who prides himself on his knowledge of the human body and how, through his custom programs, he can get you the body you want. Personally, I like a trainer who'll push you. Perhaps it was based on my request to be pushed but, he wouldn't let me get away with any shortcuts. Highly recommend. Nice guy, hard working and good at what he does read more

I started working with Jake a month and a half ago and he has been a game changer for me. I've lost weight, lost body fat/gained muscle, have more energy and better mood. It's really convenient that he comes to your gym...as he says, "all you need to do is show up." I generally don't like working out because it has always felt boring and I don't know my way around a gym, but he makes it physically and mentally challenging in a way that makes you feel really good about yourself, and enjoyable. He also tracks you in apps and checks in if you need that type of encouragement, does food planning...he's great. Lastly, he incorporates some life coaching into the workouts if that's something you're looking for. I just wanted to tone up and blow off steam but have experienced so many other benefits. Can't recommend him enough. read more

My fiancé and I have been working out with Jake for the last 5 months, and we are very happy with the results we are getting. I am 5'2 and 112 lbs, and my goal is to lose fat and tone up. So far, I lost about 4% of body fat which is a lot for my height and weight! He has been providing us personalized diet (macros as well as tips for healthy eating) and workouts we could do on the dates we do not work out with him. He listens to your goals to tailors workouts and pushes you hard even when you don't want to. Not only he is a great trainer but also such a fun person to get a training from. Overall, we are more than pleased that we decided to go with him over other trainers! read more

Been working with Jake for a few weeks now and already starting to see and feel results. He is really insightful and has helped me see past the long standing plateau I have been stuck on in regards to my fitness goals. Looking forward to the next workout! read more

Completely awesome trainer with great sessions. Has helped me with form issues, flexibility and set me on a workout plan that has been efficient and getting great results-to the point where friends of mine randomly compliment me on the changes the've noticed. read more

Within a month of working out with Jake, I've lost more than ten pounds, my body has tightened up and I feel terrific. I've used personal trainers for over forty years and Jake is one of the best I've ever met. I never quite got the link between nutrition and exercise until Jake put it in simple, understandable words. He is someone who cares, checking in by text on a regular basis, and someone who is committed to helping people reach their goals. I highly recommend him as both a terrific trainer and a wonderful person. read more

I've been training with Jake for a couple months now and am getting fantastic results. I'm not a big guy but a solid combination of diet and training has resulted in a 10-pound weight loss and a very noticeable difference in mass. Jake's reliable, easy to work with, understands how to push you and is great with follow up. And very importantly, he has a solid understanding of the body and is able to push you while preventing injury. Dude's got my full recommendation. read more

Jake is amazing. He cares to help his customer and do the extra mile. He will help you with your diet, exercise plan and motivation. Many times he put in extra 30 minutes out of his time into the session to improve the session and give some more personal attention. Highly recommended! read more

Jake has been training my fiancee and I for around two months now and we could not be happier to have found him. 10/10, would recommend. We have a smaller gym within our apartment building, but Jake does a great job of maximizing what equipment you have available to you. I've found Jake to be an excellent communicator. This is important not only for establishing long term goals, and also gauging progress along the way. In previous spurts of going to the gym, my technique was never the best and I believe this caused me to overcompensate with larger muscles (back, shoulders, etc). With Jake, I've been able to fine tune the mechanics of each exercise and really isolate the muscles I'm intending to work. On top of it all, he's a great guy and a pleasure to be around for the hour of working out. read more

Jake has been my personal trainer for over 3 years now and I recently started joining his Tuesday/Thursday morning bootcamps. They're a great way to start the day and it's a fun way to mix-up my workout routine. Jake is a knowledgable, professional, and a great guy. Highly recommend. read more

I've tried a few personal trainers over the years and Jake is truly the best I have experienced. His passion energy and knowledge over flows into the workouts!! I push myself harder during each workout with Jake and when I feel I can't do another set Jake encourages me to step it up to the next level. Jake has interest in your development, he really cares about the results and is fully committed to your personal health goals. I'm continuing with Jake for sure... Andrew Melford read more

I've lost 15 lbs. and put on considerable muscle while working out with Jake. Jake isn't just professional and skilled as a trainer, but he's a great guy and a pleasure to spend time with during workouts. A rare combination. I'm eager to see where I'll be in months to come. Thanks, Jake! read more

Jake is an excellent trainer. He is very personable and knowledgeable. He immediately assessed my diet and got me on a program to lose weight. I had the goal of losing about sixty pounds. We promptly started workouts in the park three times a week with free weights and I began to get in shape. I already lost about six pounds in a couple weeks. Jake also managed to locate one of the nicer parks in los angeles. He tailors the workouts to your needs and also sometimes checks up on you. One time I was eating a large cheesteak and a chocolate milkshake and I received a text- "Are you sticking to your diet?" Bottom line: Jake will get you where you want to go with your fitness. read more

I was 58 years old, overweight, winded by a flight of stairs, in pain every morning....and Jake is bringing me back to life and health! He knew exactly where and how to start helping me build strength and stamina, and pushes me to my limit with kindness and humor. I've been working out with him for about 9 months so far, and my energy level is way up, and my pain is way down! I'm still at the beginning of the road, but I have full trust in Jake to gently (but firmly) push me toward better and better health. He is so reliable, punctual, available, accommodating, never judgmental!!, and really a great guy. read more

I spent a year training with Jake. He was amazing. He took the time to learn about my goals and then helped me push them as I grew. He was amazing about scheduling and would drive and meet me at the gym where I was comfortable working out. I went from low strength and stamina to being able to bench and lift well past my own body weight. He was also amazing when it came to tackling negativity and was thoughtful and encouraging. He is a great trainer that focuses not just on the physical health but mental health as well. I grew more comfortable with working out as well as with myself. I am a strong more confident person and Jake was a key player in my transformation. read more
