About Robert

Hello! I am a former professional soccer player, former Head of Strength and Conditioning for Phoenix Rising F.C., and ACE certified personal trainer seeking to help 1,000,000 realize and take steps toward their full potential through fitness, nutrition, and a healthy lifestyle. 

I've been training for almost 15 years and worked with a wide range of clients (hundreds of them) ranging from aspiring pro athletes to busy parents to sedentary older adults.

I originally became a trainer to help combat the youth obesity in this country. While that is still a primary goal, I have also fallen in love with helping people of all ages and abilities reach their fitness goals. I come from an unhealthy family history, and it's my goal to be the first Acosta male without heart disease, diabetes, and other lifestyle-related illnesses, AND to lead as many people away from that lifestyle as I can!

Lose weight, build muscle, burn fat, get stronger, improve performance...No matter what your goals - I would LOVE to help you!

My favorite client story

I trained a 40-something year-old mother and her 16 year-old daughter for about a year. They both lost over 50lbs in that time, and just being able to watch the transformation of not only their bodies, but also their minds and relationship with each other was very special.

My favorite exercise

Any variation of squats, lunges, and deadlifts!

My favorite quote

Walk The Talk.

My training philosophy

I seek to empower others to realize and achieve their true fullest potential through nutrition, fitness, and healthy lifestyle habits.

My training experience

Over 10 years of experience working with clients of all ages and levels ranging from 6 year old soccer players, to 80 year old sedentary individuals, to pro athletes, to people suffering from obesity

I went to Robert when I was 220 pounds.. I have had back surgery and have eating issues.. Robert helped me emotionally get to a point where I was strong enough to help myself. He pushed me everyday to become a better person. I met Robert for training and it was the hardest thing I’ve ever done. Inwanted to cry or puke when I left... but the next day I always felt like a million dollars and couldn’t wait to get back! He helped me to get into shape and I lost 50llbs . He also wrote out a workout plan for my daughter who is a soccer player after she broke her ankle and tore all the ligaments .. Robert is very professional and knows what he’s talking about!!

When I need a strength-training plan, I always turn to Robert Acosta. His plans are challenging, utilize compound movements that save me time while still accomplishing my goals, and include creative exercises that keep my workouts interesting and fun. These are key components to my fitness, as I’m a runner who must fit in workouts around raising toddler triplets. I’ve used Robert for over 5 years—including during pregnancy, postpartum, and race training. The workouts he designed postpartum helped me gain back my fitness within 8 months of giving birth and transitioned very well into the workouts he designed for my first half-marathon. I look forward to a continued partnership with Robert as I continue to run and set more challenging racing goals.

I had the pleasure of working with Robert Acosta when I first started my journey to a healthier life style. Rob was the first trainer that I had ever worked with. His positivity is contagious. He offered encouragement as he was guiding me through my workouts. Under his guidance I was able to achieve more than I had imagined possible. He always had faith in me when I wasn't so sure of my abilities. He was patient with me as I adapted to my new life style. I had great success while working with Rob and highly recommend him.


Robert worked with me for more than two years as a personal trainer. With his help, I learned how to lift weights properly and he showed me what it takes to achieve a goal. He was always positive, timely, encouraging, and respectful. I highly recommend him as a trainer.

I've just finished my 4th session with Robert. I can already see improvements. He's upbeat and fun to work out with each time. He's helping not get me in better shape physically with the workouts, he's helping me fine tune my diet. He has a wealth of knowledge. I thought I was eating pretty healthy, but not in the way I need to for the goals I've set. I look forward to signing up for me sessions.

great trainer - will train again with Robert. I've had a personal trainer for 15 years and a member of FYT for 5. I visited Arizona for a week and worked out with Robert 4 times. I def will work out with him again when i'm back. I needed someone who knew the body as well as i know mine given my back pain and injuries and Robert was able to dial in the program immediately and moderate during the workouts. great workouts for all levels given his background in fitness and wellness.

I have been working with Rob Acosta as my personal fitness trainer for almost 2 years now, and I couldn't be happier with the results I have achieved. Rob is an exceptional trainer who is highly knowledgeable, motivating, and dedicated to helping his clients reach their fitness goals. From day one, Rob took the time to understand my specific fitness needs and created a personalized workout plan that has pushed me to new limits. His expertise in various training techniques and exercises has allowed me to constantly challenge myself and see continuous progress. What sets Rob apart is his ability to not only provide effective workout routines, but also to provide invaluable support and guidance throughout the entire fitness journey. He has been by my side, encouraging me during tough workouts, offering nutritional advice, and providing the necessary accountability to stay on track. Thanks to Rob's guidance, I have seen significant improvements in my strength, endurance, and overall fitness level. I have also noticed positive changes in my body composition and have gained a newfound confidence in my abilities. If you're looking for a dedicated and results-driven personal fitness trainer, I highly recommend working with Rob Acosta. His passion for fitness, expertise, and genuine care for his clients make him an exceptional trainer. I am grateful for the progress I have made under his guidance and look forward to continuing my fitness journey with him.

I have worked with Robert for several years now. The journey in my health and wellness transformation has not been an easy one… but with his expertise and guidance, it has been nothing short of incredible. I simply could not have done it without him. I am a 43 year old mom of 4 and wife, business owner, perimenopausal and with some health challenges. Robert has actually taken the time and resources and helped me through it ALL. My emotional and mental growth has almost succeeded my physical transformation. His knowledge in fitness and nutrition, personal accountability (he walks the talk), awareness to learn and teach, his patience and true passion for what he does, and the standard in which he holds himself as a trainer and professional athlete is everything you could ask for. He now trains my family members, he has become a lifelong friend, and I HIGHLY recommend him no matter your age or circumstances. He is your guy! If you do the work, the results will come. And Robert will hold you to it.

Robert Acosta is an exceptional fitness/health coach and mentor. He is consistent, timely and full of positive energy which is encouraging and helpful for motivation. I have reached a few fitness goals while working with him. He will work with you and encourage while not letting me succumb to the excuses of life. He is well educated in the field and will give you a beaming smile each time you meet with him… long story short, he is excellent.

Amazing attitude, always positive. He is understanding and will work on building a plan that works best for you. He will also educate you on the importance of nutrition and fitness. He has changed my perspective on fitness and I’ve finally been able to make the progress I’ve wanted.
