David is a solid fitness coach. He is super smart about all things related to the human body, cardiovascular function, exercise, and nutrition, and has taught me a lot about how to fine tune my body and diet to reach my fitness goals. He's incredibly professional, and is truly dedicated to his work and clients. I was impressed by how well he listened to my needs, customized my training accordingly, and positively encouraged me along the way. Finally, I really appreciated his attention to detail - focusing on proper form and selecting the right exercises for me was critical to my success

It's hard to put into few words how great David is, but I'll give it a shot. This man oozes knowledge and passion about physical training and rehabilitation like few others I have ever met. David is one of those special individuals who talks the talk and walks the walk when it comes to knowledge and advice on diet, exercise, posing... you name it - David can help you with it. He has given me the tools I need to work towards being my best self, all while always doing it with a smile on his face. He's one of a kind and I highly recommend him as a trainer.

I love working out with David. We've been together 2x per week at Alex Fitness for the past several months, and I look forward to every workout. In addition, I've seen rapid strength and muscle gains working out with David. He is super knowledgeable about the exercises, but also a great resource on diet and nutrition as well.

I leave every workout with David sore, stronger, and feeling extremely content for the rest of the day. You can't beat it!

David is the real deal! Very professional yet fun to train with. He's very knowledgeable in both working out and diet! When I met David 3 years ago I was around 25% body fat and not too healthy in general. Last year I was down to 8.5%, I feel so much better and much healthier He's given me so much help and motivation, I owe a lot of it to him.

David is hands down one of the best trainers in the Bay area. He helped me push my training and dial in my nutrition to get more out of my body at 40 years old than I did at 20. David brings experience, energy, and a positive smiling attitude to every session. He follows up with advice and planned routines, so you get his expertise even after your session.

Whether you are looking for a new routine, some professional training advice, or to just to look fantastic on the beach this summer, Dave is your guy. It's been worth every penny for me, and the results on the field and in the mirror speak

Having access to David makes the path to your fitness goals as short as possible. Injured? No problem, fixing you is what he DOES. Trying to get your diet straight? David makes it simple. Want to take your physique to the next level? You won't find a more knowledgeable partner. David is a rare trainer with an incredible experience base that lets his clients work around their limitations. I trust him 100% to understand my goals, help me make a plan and push me to execute it.

For me, remaining injury free in the gym is a serious obstacle. Too many times, I've been making great progress

Deciding to get back into the gym after having a baby was intimidating to say the least, but deciding to work with David was everything I could ask for. He is professional, yet personable and more than a trainer, but also a motivator. He inspired me to make the necessary changes in order to achieve my health goals and keeps me motivated and committed to my goals. He is not only helping me get back to my pre-baby body; he is inspiring me to strive for better! Being intimidated is history...being strong and confident is MY STORY!

I have trained with 6 different trainers over the past decade and David is hands down the best. Don't get me wrong, my former trainers were absolutely knowledgeable, but Dave is inspiring on a different level. He cares enough to go above and beyond the requirements of a standard trainer. Even though I started training with David in my 30's, my modeling career has never booked more or looked better. Dave will bring out your best aesthetic

There are no words. David Janke is a true master of personal training. I have worked with 100+ professionals over the past decade. As a trainer of trainers I must say I refer to few exercise physiologists as "teacher" but D. Janke is a true teacher of mine. For years Dave has been a personal trainer to heart attack and stroke victims, while simultaneously winning the SF Master's Physique Championships! If you're interested in transforming with an inspirational individual, look no further than David!
