Train 4 Life® Philosophy

An athlete lives in each of us and is capable of achieving more and being stronger than we ever thought possible. The body is the athlete’s tool and is uniquely composed and shaped, responding to nutrition and physical exertion in its own way. Train4Life teaches clients to define and master their strength, athleticism and life balance. Hard work and lots of support? YES! Fad diets, insane workouts, quick fixes? NO!

Best trainer I’ve ever worked with

Screen Shot 2016-06-21 at 4.01.05 PM

I have been working with Jenny for almost 3 years now, and she is the best trainer that I have ever worked with. She is very professional and very knowledgeable, but there are lot of professional and knowledgeable trainers out there. What sets Jenny apart from the others is her ability to figure out what exercises and regimens work best for the individual client, and what motivational style will best get you moving. She wants to understand what makes you tick, and uses that to build the best possible program for you. With Jenny, you are not getting Crossfit, nor P90X or Insanity or whatever latest hardcore workout scheme is in vogue, you are getting a lifestyle change that you can easily accomplish, and you will learn workout routines, exercise regimens, and nutrition guidelines you can utilize for the rest of your life.

I completed my first 50k!

I always thought that I ‘knew’ how to work-out and could make myself train for anything. After a failed attempt at a 50k hike, I realized that I needed help! Jenny listened to my goals to create interesting and challenging workouts. After just a few weeks, I could feel the progress I was making and Jenny continued to adjust our training sessions to ensure I was being challenged. Through working with Jenny, I gained the confidence to continue training hard even when we could no longer train together. Now I am proud to say that I have just completed my first 50k and I would have never gotten to this point if Jenny hadn’t steered me down the right path!

I could not recommend anyone more

Screen Shot 2016-06-21 at 4.05.39 PM

Over the four months that I trained with Jenny, I saw an increase in muscle, reduction in body fat, and improvement in self-image. Each workout was tailored to me to keep me motivated and engaged. Jenny consistently pushed me out of my comfort zone and into workouts I didn’t think were possible. More than just a trainer, Jenny became a friend and adviser. I could not recommend anyone more!

She was awesome!


I started training with Jenny when I started writing my dissertation in graduate school. I needed some structure to may days/weeks and working out was a good way to start. I also wanted to learn more about how to lift safely as I think women are too often scared away from the weights because the “bros” are intimidating. She was awesome. I regularly learned new exercises that I use to this day and left feeling like I had been pushed much further than I would have been able to on my own. I even *bought* a bosu ball for myself! I…felt stronger, more toned, and more able to pick up those weights and know what to do! I’m psyched to continue to use her online training. Now that I’ve finished school and have a less flexible schedule using her routines at home will be great.

Jenny is extremely knowledgeable and reliable

Screen Shot 2016-06-21 at 4.16.44 PM

Jenny is on call 24 hours a day with whatever questions you may have. She is extremely knowledgeable and reliable and, above all, exceedingly dedicated and self-motivated. She creates unique workouts specific to your goals. Unlike most trainers, she does not categorize her clients and make general food and nutrition plans that will cater to a group of people. More specifically, Jenny focuses on the individual and develops a comprehensive plan that will suit you and only you.

Jenny places a tremendous amount of emphasis on what type of food should be put into the body as she possess an in-depth knowledge on the subject; which is unrivaled to any other trainer that I have come across. She stresses the basics and gets an understanding of your goals and creates an all-inclusive plan-of-attack. In order to develop & establish a foundation, Jenny stresses the importance of mastering a proper technique in every single exercise and in every single repetition. There is no facet of health and fitness that Jenny is not well versed or trained in or question that she could not thoroughly answer.
