Celebrating over 16 years in the fitness industry!

Did you know?

Our founder, Jennifer Khosla, has been in the fitness industry for over 16 years?!?!

Read on to learn more!

Jennifer, how long have you been in the fitness business? How did it start?


I have been in the fitness industry for 16 years! I can’t believe how fast time has gone by and all the changes. I started working at the local YMCA in Northwest Connecticut when I was 16 years old. My job was to teach members how to use and adjust the many exercise machines, I had to clean the machines and monitor clients while they used them. During that time, I was available to provide exercises to members, and answer fitness questions. You may be wondering how I knew so much. I was like a sponge, I learned everything I could from trainers, DVDs, and books. I was only 3 years old when I started dance classes and gymnastics, and team sports in school began early on. I loved playing sports year round, but I found that it wasn't about being competitive. I liked the sports because I loved the feeling of being physically fit. I started working with the Athletic Trainer in my school to learn more. Eventually, I designed an internship for Athletic Training at our school for myself and future students. I knew then that I needed to find a career that would make fitness and wellness a part of my life. I have to thank my brother for giving me my first yoga mat. It was the start of something beautiful. Yoga was one of the many pieces to my education and journey of fitness and wellness.

Springfield College was the top school in the nation for sports medicine. I knew that was where I had to be to make my dreams come true. I went on to receive my B.S. in Athletic Training, with a minor in Nutrition.

I started personal training during my time at Springfield College, and actually took my first personal training course through ACE when I was only 18 years old. I have been working actively as a personal trainer now for 11 years! It’s hard to believe, the past decade has flown by! I worked as a personal trainer in Boston for several years while furthering my nutrition education, and later decided to combine all my passions into one total wellness business. 

California here I come! I wanted to get my yoga certification at one of the leading yoga studios in La Jolla, California. I trained with some of the top Yogis in the field. This was important for me personally as well as for future clients.

I have worked in several gyms, private training settings, yoga studios, and owned two fitness and wellness businesses in New York and currently now in Florida. I officially opened Lean and Green Body® in 2015, and now lead a team trainers, coaches and fitness & wellness professionals here in Naples. We are a growing national brand with clients in Florida, New York, Connecticut, Ohio, Minnesota, Georgia, and California. We currently see clients in their home, community gyms in Naples, Florida, or at our studio on 5th Ave S in downtown Naples, host weekly yoga classes at our studio and live stream, as well as see clients nationally through live stream technology.

It is amazing how far I have come professionally in the last 16 years! I could never have imagined my career what it is today, and I am grateful for this journey everyday! My clients and my team continue to push me daily to be the best leader in wellness and fitness that I can be. This is only the beginning for me and Lean and Green body®.

How did you first become interested in exercise and movement?

Growing up I always participated in sports. In high school I settled on my favorites, volleyball and running, and now, I am primarily a runner. When I started running longer distances I became hooked! I had found that “runners high”! I wanted to learn how the body functioned and moved together.

When did you become a CPT, and how long have you been training? What is your favorite part about training your clients?

I have been training clients for just under a year. However, I interned for two semesters my senior year of college. One was at an athletic/performance facility while the other was at a wellness center where I saw more of the geriatric population. So I guess I have two years under my belt, and I would say it’s been well-rounded. My favorite part of training is the challenge of combining (health) limitations with individual goals to create an exercise program that will be successful.

I understand you recently received a new certification, please tell us more about this.

Recently I flew up to Indianapolis to become certified in Rock Steady Boxing. RSB is a program that fights back against Parkinson’s disease. The classes involve non-contact boxing as well as functional strength, footwork, dexterity, flexibility, speech projection and balance (and sometimes some trivia!). This program is truly inspirational. I am able to bring a quality of life to affected individuals who didn’t know how capable they still are.

That is amazing! I look forward to seeing the positive impact this program has on our local community.

You are about to pursue your Masters and Doctorate in Physical Therapy, what interests you most about the field?

While studying in the Exercise Science program, I learned a lot about biomechanics and kinesiology and a bit about pathologies. I have a passion for combining all these factors. I have plans to specialize in pediatrics or Parkinson’s (very different, I know). Physical therapy is the best way for me to learn more about what I am passionate about while making a positive impact on other peoples lives and futures.

What advice do you have for our readers about pursuing your dreams?

If you have a dream, go for it! Don’t let outside factors influence your decision or slow you down. Follow your passion and never doubt yourself. Confidence will lead you to success.

Kerri currently teaches Rock Steady classes on Tuesday and Thursday 11-12:30 and Saturday 1-2:30 at Bonita Bay in Bonita Springs, Florida. 

Knowledge Is Power

personal training | ISSA | lean and green body

Sorry I’ve been so absent! I took a week off from the blog and locked myself in my office to study. I am a firm believer in always growing, always improving, always learning. 

“Knowledge is Power.” -- Sir Francis Bacon

I just completed the International Sports Science Association (ISSA) Personal Training Certification! Huge accomplishment! Months of studying and preparation...followed by a certification test that took me 6 hours to complete...but was well worth it when I found out I got an A!

I took my first Personal Training Certification 11 years ago, and have been working as a personal trainer for the past 11 years. With the growth of my business and expansion of the Lean and Green Body team I decided to re-certify for Personal Training with a new, and in my opinion better board of certification. We are requiring all of our Personal Trainers to be certified through either ISSA or NASM; so I decided to re-certify in order to be on the same page as the rest of my trainers. We want the best and most educated staff. To be the best, you have to have the best.

In order to be the best you have to continue learning and growing - personally and professionally.  After graduating from Springfield College I completed an additional 4 years of post graduate work to compile my base of knowledge and degrees. Since then I continue to study, take courses and continuing education credits every year. In the field of health and wellness things are always changing, and new information is always being discovered. You must stay on top of the changes and discoveries to be able to offer the best services and experience to your clients.

Going out with the fiancé tonight to celebrate!
