    Kristin is one of a kind. She motivates me every single time I need it. I've lost 70lbs and lowered my blood pressure since I've been with her over the past 6 months. My doctor was so happy she hugged me.

    After every workout I've done with Kristin I've felt like I've accomplished something. I feel good overall and I have a different mentality about working out. I have confidence that I will keep improving. I am beyond grateful to Kristin for helping me.

    I've been working with Kristin for a few years. Working with her has really motivated me to stick with her program. I find working with her to be fun and the diversity of her workouts/classes keeps me from getting into a boring routine. I know I would not have it in me to push myself the way I do when working with her if I tried on my own.

    I will be 64 in December. I have been utilizing Kristin's services for approximately two and one-half years. I was never interested in seeking training assistance from a personal trainer before and instead would work out on my own. Of course, travel and paperwork would prevent my workouts. I now find that having a scheduled appointment with my trainer has assisted me in making the time I need to become healthier. It has worked. My blood pressure, cholesterol, weight are considerably below the beginning workout levels. Kristin has been exceptional in motivational discussions and discussions relating to proper nutrition. She is able to tailor a workout for each individual to assist them in reaching their personal goals. She has a contagious smile and personality which, believe it or not,actually makes sweating fun. I would strongly recommend her to anyone considering a personal trainer, especially for the first time.

    I am in my Mid 20's and was looking for a personal trainer who wouldn't scream at me and would motivate me to train hard and shed the LBs I had put in after a cross country move. She and I have been training for about 2 years now and I can say I have never felt better in my life. I can confidently run farther than I ever have before and I feel stronger than ever. Her approach to training is very approachable and will make you feel like a "beast" in the best way possible of course. Kristin is a supportive and driving force -she will make you push yourself harder and further than you thought possible. For example I ran my first "Tough Mudder" this October. If you had asked me to do one of those 2.5 years ago I would have laughed in your face. But I did it! If you are looking for someone who you can relate to who can push you to get your body where you want it to go Kristin is your girl with out a doubt! -Lauren P. , Philly

    I have worked with Kristin Santos for more than a year and I can say the Kristin does a great job. She keeps me motivated to reach my goal. I have definitely noticed a difference in my body. I have lost over 10 pounds and 4% body fat. She deserves more than a 5 star rating in my book. Thank you for everything Kristin!!!!! Keep up the good work.
