My name is Nick and I'm a part of Team Cosmo BYU.  I was the one without shoes since I sprained my toe last week.  I wanted to thank you for coming to our practice on Thursday and pushing us to a new level.  It put some things in perspective for me.  How far I can push my body and mind...and also how far I have to go.  But I like a challenge.  I plan on making some lifestyle changes that will help me reach new heights which you have shown me that I am capable of reaching.  Thank you for being inspiring.  Next time...I will not owe any burpies at the end.



My name is Nate, Jill has been training our group of Army ROTC cadets. I've been an avid workout nut since running track (pole vaulting, decathlon) in high school, so I've spent my fair share of time in the weight room and on the track. As an athlete she has helped me improve in agility and grow in lean muscle--overall I feel healthier for it. Jill's workouts have opened up a world of new plyometric and calisthenic exercises/movements for me, and to boot she is a tremendous motivator.


-Nate Beck, Provo

“Jill has an incredible talent of motivating others with their goals. Her example alone inspires us to greatness. She motivates you to move forward with her charming, infectious smile. While her TBBC program challenges your physical body, you will leave with a mental “high” that comes only with accomplishing what you previously thought was impossible.” Hugs,Catherine










I’ve tried many of the popular fitness dvds out there, but I have to say, hands down, Tight Body Boot Camp leaves those other fitness programs in the dust! Not only will you learn so much from Jill as your in-home trainer, but you’ll start to realize how you can start to transform your body and see REAL results! I know that when I feel tight, I feel healthy and full of energy!  Thank you so much Jill!

Jill's program pushed me beyond what I thought I could do, giving me confidence and amazing improvements in my strength. I especially love the Core Essentials and Core Extreme! My core has never been this strong, making everything easier, from running to Pilates and Yoga to everyday activities! These are the most effective DVDs out there for achieving real results!




Jill's workouts are difficult but possible. She knows exactly what each member of the team needs in order to gain from the workouts, and how to meet our individual needs as an athlete. Plus, she is always motivating!


- Alicia


Tight Body Boot Camp has been the best work out I have ever participated in. It constantly brings new challenges into my workouts that not only improves my physical strength, agility, and coordination but also helps me build mental toughness. I have participated in several different workouts and I have never physically been challenged
so hard before. This has lead to me physically and mentally going far beyond what I ever thought would be possible for me. This motivates me to go back and participate in every workout I can with Jill because I know Jill cares about every person individually in her Tight Body Boot Camp and has prepared something in each workout that will help me along with everyone else work towards their full potential.

PS - Thank you Jill

After six weeks of training with Jill I had a whole new physique.  Jill was fun to work with, and extremely knowledgeable.  Through her coaching I have learned many valuable techniques on how to live a healthy, and vibrant life."
                                                                                                    - Katherine


Jill really knows how to customize the training for who you are and where you are at physically.  Jill has taught me to be my very best, try a little harder, get stronger and still be proud of what I can do today.  She walks her talk and is a shining example of "can do" attitude.  Her ability to teach is only equaled by her gentle and kind insistence for each student to take the next step to individual improvement.  I've lost 35 pounds since working with Jill - and found my ability to excel physically through Jill's leadership.  She reminds me that I am stronger than I think and I find it to be true in all aspects of my life. You are the best Jill!




Give an F, give me an O, give me an RTY!  I did it!  Thanks for being such a great support in my journey to well being!  See ya Saturday. (Lost 40 lbs!)

Jill is the BEST Trainer and Coach! I love her knowledge, energy, and beauty. My training has been intense, and complete. I didn’t waste a minute of my time. Jill will get you the results you are seeking at any level. Training with Jill has made me a happier person. I have more energy, greater self-esteem, and enjoy more fulfilling relationships with those I love. My sports, outdoor activities, and duties of my daily job, have all been enhanced through my training. I’d refer Jill to anyone, from beginner to hardcore athlete.

- Ron














Jill you are awesome! I loved working with you. You are great and fun and you made me work real hard! I would totally recommend you to anyone. Thanks Jill. I look forward to working with you again.  (Lost 60 lbs!)

Jill, I can't thank you enough for all that you've done to help me! I struggle to put in to words how grateful I am that our paths have crossed, but here's my attempt:

I highly recommend Jill Nix to anyone who is serious about their health! She personally designs your meal plans with your likes/dislikes and lifestyle in mind - the meals are awesome and very fulfilling, and Jill takes all the guesswork out of eating to achieve your goals. Jill's fitness plans are fun, challenging, and rewarding. Again, very personalized, Jill makes sure you are comfortable with every aspect of your workout, designing a great fitness plan to push your body to levels you may not know are possible without making you feel like you're tackling the impossible. Jill is very personable and friendly, and always willing to answer questions or help in any way. I had been working on my fitness and weight loss/health goals for some time before I met Jill, with little progress and lots of discouragement. Thanks to Jill Nix and her personal care and attention to detail I have achieved my weight loss and fitness goals by following her fitness plan and meal plans customized just for me. I feel great and can't believe what I can achieve now that I have Jill's knowledge and expertise backing me! Don't waste any more time struggling to meet your goals on your own, Jill herself is living proof that she knows what she's doing, and thankfully she's willing to share her wisdom! She does the "leg work", you take the action, and together results are guaranteed!

When January 2016 rolled around, I was encouraged by my mom to participate in a meal plan and training program. I was intimidated and came up with every excuse I could, but finally gave in and decided to give it a try. Much to my surprise, I began dropping even more weight and body fat. In six weeks I dropped from 123 lbs. to 114 lbs. and I went from 18.5% body fat to 13.1%.

                                   - Chantelle

Thanks for pushing me some Jill and teaching me good form. My legs are a bit wobbly tonight so I'll see how I am in the am! I'll give it a day rest and then go after it Thurs. I'm excited to do more and try harder. You're coaching is kind but persistent Jill- such a great combination.


- Mary



I am loving my workouts!  It is very hard at times but keep having faith in me and believe I will get better.  I have always needed someone to "hold my hand" and provide a good program for me.  I appreciate your time and efforts on my behalf.

Why did you choose Jill as your trainer?

I chose Jill because she's such a good role model, approachable, professional, and obviously knowledgeable and experienced. She is a colleague I respect and admire. She really walks the walk!
What is it you like about Jill, as a person?

Jill is so positive all the time, always smiling and encouraging. She's very warm & caring & fun to be around.
What did you like about your training program?

I liked that it was very specific for my body and my goals. It was challenging for me, but I knew that I would get results.

How has training helped you, physically?

I lost 10% body fat in just 5 weeks-- I never thought that was possible! I feel so much stronger, leaner, and cleaner. I love seeing my muscles pop. I thought I might feel more tired, but overall, my energy has been great. I've also noticed my skin looks better and my hair is growing faster!

Has training helped you in other areas of your life, as well?   If so, how?

It has given me the willpower to be more self-disciplined in mutliple areas of my life. I feel like I'm accomplishing more in my day because I'm not always hanging out in my pantry!

Would you refer others to Jill for training? If yes, why?

Yes, I already have! Jill has a great understanding of the human body and a lot of experience in health and wellness, as well as figure and body building. She can address all aspects of training.

I first became acquainted with Jill when I decided to try a Zumba class at my gym.  After one class I was addicted!  Jill's enthusiasm and fun teaching style immediately had me hooked.  Shortly after starting the class Jill became my personal trainer.  I was looking to build some muscle and tone my body, but first I had to overcome my fear of the free weights and insecurities with the gym in general.  Jill has been a truly motivational force from the very beginning.  She encouraged me and helped me overcome my fears, working at my pace while also challenging me to take risks and lift weights I never thought I could.  Her training style is optimistic and reassuring; she never bullies.  I found that I was challenging myself to set fitness goals and go beyond each prior workout session.  One thing I particularly like about Jill is that she is so knowledgeable about nutrition and holistic medicine.  I am always picking her brain about something and she happily shares her knowledge.  It is obvious to me that she loves teaching and helping people achieve their fitness goals.  I wholeheartedly recommend Jill as a trainer.

Jill is a great coach and motivator.  She was instrumental in helping me to achieve my goals and change my body.  With her assistance, I was able to shed the hardest to lose pounds and reach a body fat percentage that I had always thought was impossible.  Thanks Jill!

Jill is an incredible personal trainer and nutritionist who genuinely cares about her clients. I had several concerns going into my meal plan including: I didn’t want to be hungry, I am a busy mother of a toddler and a baby and don’t have tons of time to meal prep, and I was still breastfeeding my 8-month-old and didn’t want dietary changes to affect my milk supply.

Jill took all of these concerns into careful consideration and created a meal plan entirely unique to my needs and situation. The meals were simple to prepare, the portion sizes were plenty to keep me satisfied, and to my surprise, my milk supply actually increased. Additionally, headaches I was having almost daily due to imbalanced blood sugars, disappeared altogether.

Jill was thorough in showing me how to complete the training exercises on my exercise routine to ensure I did them correctly and efficiently. Even though I felt healthy and in shape at the start, Jill helped me recognize that I can do hard things. So far I have lost 10 lbs. and am down 5% body fat. If I had to describe Jill’s work in three words, I would say it is genuine, professional, and thorough.

I was referred to Jill for training. I’ve lost both weight, and inches. Jill’s always positive-even when I felt like dying, she was there encouraging me to follow through, and I did! Jill works me hard, with a lot of variety, and knows how to modify exercises for those who have injuries. Training has improved my endurance, for sure, as well as, physical stamina. Her training is very wholistic. Her training and various modalities help you feel balanced as a person. I refer my friends to Jill, she is easy to get along with, and very inspiring.
- Mike (Triathalete)














I chose Jill as my trainer because I felt she could help me reach my goals. I like that she cares a lot about her clients and pushes them to reach their potential. She kicked my ass. My training has helped me to do more physically then I have ever been able to do previously, with more energy and endurance. With the training I received with Jill, I feel more confident in myself. Before I was unsure and shy, now I am confident in my own skin. I'd refer others to Jill, 100%. She doesn't care about the money, she cares about making you the best you can be."

Jill Nix  is a truly excellent trainer. She is the perfect combination of tough ("Jill, you are KILLING me!") and warm ("Jasper, you are doing AWESOME!!"), and she works with the whole person -- mentally, emotionally and physically. Because of her efforts, I am stronger and more flexible, I have better balance and most importantly, working out & dieting has become fun. I recommend her without reservation. Jill's methods work 100%.

Jasper Peterson















Working with Jill helped me realize that I could push my body to the next level.  I love the feel of strong muscles giving me energy.  I gained a new appreciation for my mental strength.  Jill's positive thoughts and attitude is what I needed to heal my mental health and work on fitness goals.  After all, it takes good mental health to strengthen your body and have energy.  Her food plans were great and helped me stay focused on clean eating.  If there was a  meal I didn't like, Jill tweaked it to fit my taste buds.  I use many of the meals for my daily menu now.  I learned that fitness is a lifelong journey and starts today!  Thanks Jill!




Why Didi I choose Jill As My Trainer?:

I saw Jill at the October  2010 NPC Nutrimart Classic in Women's bodybuilding.  She has an incredible physique, and I was thoroughly impressed!  I have already made arrangements to train with someone else, However, I chose to go with Jill, because she was a much better fit for me and my fitness goals.

What is it you like about Jill as a person?

Jill is very patient and kind, and knowledgeable! She has a great temperament, and is easy to work with.  She is firm and has high expectations and will push you to do your very best. She is positive and
encouraging. motivating and is an expert at training you to be your personal best!

What you liked about your training program?

Jill was excellent at having something new to do each time, a master at mixing it up so you are never bored, your body is always guessing, and you maximize your fitness potential! I loved the mix of
traditional power lifting moves, mixed with Plyometrics,  weights, cardio, and multiple compound movements. Totally LOVED my training program!!

How has training helped you physically?

My training has helped me earn the best physique I have ever had. Without a doubt, at 40, I have a far superior physique to the one I had at 25, yet I FEEL like I'm 25! It has helped my lower back strength,
and I am virtually pain free all the time!

Has Training helped you in other areas of your life? How So?

The Training has helped me to be accountable for each workout, and inspire me to keep beating my own records.  I've worked out at the gym off and on for 20 years, but was never able to achieve the results
I've been able to obtain while working with Jill.  I was also able to overcome my stage fright, and compete in my first competition because of the confidence I've gained while training with Jill.

Would you refer others to Jill for training? If Yes, Why?

I would refer anyone to Jill regardless of age, sex, or physical condition!  I have full confidence she can whip anyone into shape!! She is very personable and would adapt a great program to suit the needs of
your fitness goals.  I am absolutely certain you would not be disappointed, and your results will exceed your wildest expectations! Jill is by far, the best hands on trainer I have EVER worked with! Her Tight Body Boot Camp Program is Superior to all others.  

Love you girl!!  Thanks so much for everything you've done!  You are such a lovely lady, and I am truly honored to call you my friend!

In early 2015 I had decided I needed to lose 20 pounds. I got talking to Jill at the gym and was so impressed with her and her amazing work outs and her amazing body, and I decided to have her help coach me through this weight loss. She created an amazing meal plan which I ended up following for a few months until I lost the weight. I had some events that caused me to go off the meal plans for a day or two or week, but then got right back on.  I met with Jill on a regular basis for weigh-ins and measurements. She is so positive and encouraging!! By June I had lost the 20 pounds, just in time to participate in the Wasatch Back Ragnar. I would totally recommend her to anyone wanting a fitness or weight loss coach.


Thanks Jill!

I was a member of U.S.Army Rangers for 3 years, and I have done much hard work, and physical training exercises. After discharge and many ups and downs, only one person with her amazing advise: spiritually and mentally, and with providing amazing diet program, and body building program.... put me back on track. That was Mrs. Jill Nix

I have lost 41 pounds in 4 months my body is in amazing shape which I get compliments from everyone. My own family is in shock.  If one day I don't exercise, I absolutely feel down. Her advise and mentoring made me a different person, and I am sure she will do the same for everyone. 

I have seen, listened to, and tried many other programs, but no one can design a specific program like Jill, for you.
