Personal Training Philosophy
From these experiences, I provide clients with appropriate challenges, from small and baby-step-like to gut-busting endeavors. If you need a cautious approach, we can go slowly. If you want to be tested, the black shirt goes on and the sadistic side surfaces. Whatever is appropriate for you. I‘ll throw in a dash of creative variety; a few funky, off-the-wall training techniques; some humor; and voila!

Testimonials
“I started working out at NIFS in November 2006 with Emily Jackson as my fitness instructor in the Weight Loss Program. Emily has been the primary reason why I have continued attending the sessions all these months. I usually lose interest after three months or so because I get bored and tired of the commitment, as well as not being able to see any discernable results. Working with Emily, I am still enthusiastic about coming to NIFS two times a week even though I start at around 7:00 am and I am not a morning person. Emily has been very good about designing workouts that challenge me but not so hard that I get discouraged. She pushes but not in your face too much. She also is very creative in selecting exercises so I do different things and the workout does not become repetitive. Her program is creating positive results because my husband said he could tell a difference. I really have not lost that much weight but my clothes are fitting better. Emily really knows her stuff! She also has a great positive and energetic personality that makes her fun to be around, and she genuinely cares about my achieving success through the NIFS program. Emily is the real deal: educated, talented and committed to the success and good health of her clients.”
