Abundant Health

The most successful leaders follow a routine that allows them to remain in good physical and mental health.

About Serina

Hi there!

I am the founder of Mind Body Gainz Fitness, an online coach and trainer, out of Better Late Than Never Training (BL8TN) Facility – Scottsdale, AZ. I graduated with a Bachelors of Science in Psychology and hold multiple fitness and nutrition certifications.

My passion is sharing the gift of fitness with all of you. I believe that fitness goes beyond the physical transformations we achieve. If implemented correctly, the positive effects on the mind, soul, and physique are truly limitless!

Throughout my journey, I have tried numerous methods in the pursuit of various fitness goals. In the end, I built a lifestyle that allows me to achieve mental, physical, spiritual health and fulfillment.

A combination of dedication and balance allowed me to leave behind the extreme and unenjoyable “diets” and workout programs. I replaced these with a lifestyle of sustainable nutrition and consistent workouts that I enjoy!

My program emphasizes compassionate discipline and allows my clients to discover a balance of nutrition and workout intensity that fits their lifestyle. This approach will allow you to still eat the foods you enjoy, have free time to spend on things other than fitness, and achieve sustainable results.

Please reach out if you have any questions or are ready to start your journey today!

Your body hears everything your mind says. Practice speaking kindly to it.

Yes! I believe that with sustainable results, it’s important to create sustainable habits. So I create your plan in a way to eat what you love WITHOUT giving up your favorite foods.

Everything is custom so yes, I can create your training program to be from home with no equipment required and you don’t need a gym if you don’t have access to one.

Within the first week your clothes should start fitting better and your energy levels should increase along with a decrease in bloat, inflammation and improved digestion. The more consistent and committed you are the better results you will have.

Yup! Videos and descriptions for each move along with key tips will be accessible to you!

Not an issue at all! On the intake form you fill out, you will let me know what your daily schedule looks like and I will accommodate both your meals and workouts to work around it! We can make your meals very quick and simple and ‘on-the-go’ friendly and we can even make your workouts work from home if you don’t have time to get to the gym!

My Clients Say...

Serina is by far one of the best trainers I have worked with! Such a sweet sweet soul ✨. Not only does she train physically but mentally as well. A positive role model. She inspires me and motivates me to want to better myself. She’s always there to answer my questions and takes her time to understand my individual goals. 💕

Marvin D.
Hands down the best choice I have made training with Serina. I am so pleased with the results I am achieving. Her knowledge, encouragement, and motivation are immeasurable.
Kim T.
Serina has been a pleasure to work with. She is a very attentive listener and truly wants to help you accomplish all your goals. She’s different than any trainer I’ve ever had and it’s because she is not only focuses on your body goals, but also your mindset, which is essentially where all the power comes from! She is also absolutely beautiful, funny, and very down to earth. Thank you Serina for coaching me!!!
Tamara K.
The fitness fanatic who runs this business has taught me more than just maintaining my physical fitness. She correlates the healthy lifestyle with keeping a strong mind and will. Before I joined the Air Force, she unknowingly taught me lessons that the military instills in to you about nutritional principals, exercising and having a warrior mentality. Her knowledge was advantageous in surpassing many of the trainees in the physical and psychological aspects of BMT. She is caring and supportive, couldn’t have asked for a better coach! Thank you Serina!
