Referee Advantage Reviews

John

NBA Referee

Before I started working with David, my knees and my back hurt on a daily basis. My fitness routine was outdated and the same sort of training I used while playing college basketball. Now, with my current routine, I consistently improve in athleticism while the programming continuously
builds up my body which I love.

Working with David has created a big shift in mindset to simply be strong mentally day in and day out.

Now my life is great! The workouts are still challenging (LOL) but they have strengthened my weaknesses in my body and given me a new variety of movements which I like a lot.

If you want to invest in your health by working with David, DO IT! He understands how to help you become the best version of yourself. He programs to work on your weakness and make you healthy overall – not just from an aesthetics perspective.

Luke

Collegiate Referee

I joined Referee Advantage to fill out my frame and take my endurance to the next level.

David tailored workouts to help me become better every day. At the start, we worked on building a solid foundation with form. We then worked up to heavy weight and high reps in a variety of movements to achieve my goals. It was also helpful to set my workouts to what worked in my schedule.

Now, I’m an overall better athlete. I am faster, lifting more weight for more reps, more flexible, and running in the 4th quarter with the same speed and burst as I had on the first play of the game.

First, I am able to keep beating players up and down the court all game long to put myself in the best position. Second, I fill out my uniform better than I did before. I look and feel more confident on the court.

If someone is on the fence about working with David and Referee Advantage like I was, I would tell you to give the team a shot! They get results and genuinely care about you and your success.

High school & collegiate basketball, soccer, lacrosse

Before starting David’s program, I knew what my goals were, but I did not know how to get there. I went to the gym for years but was not getting the results I wanted. With David’s help I was able to get there quickly, and the best part is, I now know my progress will never stop.

I have always been a little skeptical about personal training or coaching because of the fear of spending money and seeing no results. After talking to David, I could tell how passionate he was about his work which made me feel comfortable. When it comes to fitness, he is enthusiastic, motivating and deeply knowledgeable. He pushes me to meet my goals and he makes my workouts fun and challenging at the same time.

After doing David’s program for only five months and counting, I cannot say enough great things about the positive impacts his program has had on me. There have been incredible results and I can see and feel the difference, and I feel amazing!

When it comes to personal training, we demand the best as athletes and referees and I can tell you, David is the man! Going with David will be one of your best investments you make for yourself. He will make you feel and look confident and amazing along with the great results.

Gabrielle

NCAA Women's Referee

When I say David Zetts is the real deal, I mean it! He knows what he’s talking about, a great teacher and overall just a great person. We hit our initial goals on improving mobility, getting stronger 💪🏾, getting leaner (aka 4 inches off my waist) and increasing my speed. Now that I’m back in the gym and the season is quickly approaching, it’s time for us to revisit and revamp the goals list. Thanks Coach and I’m glad to be a part of your #RefereeAdvantage program!

Nathan

NCAA DI Referee

My life before I started Referee Advantage was pretty active. I would find workouts online and exercise 5-6 days a week. I was staying in shape but not seeing the results I wanted. I also was not tracking my numbers so I never really knew if I was making progress or not.

When I met David, he immediately gave me accountability structure and proof of improvement.

Now I train 3 days per week with the most results I’ve seen in my life. My lower body is so much stronger than ever before which will help prevent injury and provide longevity in both of my careers.

Side note: I love golf. My max yardage on my drive used to be 265. After working with David, I’m now hitting it easily in the 315-325 range!

One tip I can provide to you is “pull the trigger.” Everyone in officiating works out and wants to be in great shape. But few of us have workout plans tailored to you specifically. David does an exceptional job of making your workout plan for you and making sure you get the best out of yourself.

John

I joined Referee Advantage because I wanted to look more athletic and run faster.

David and his team tailored the program to my specific needs and goals.

Nowadays, I have never felt better or looked better in my life!! I love the way I look in my uniform and my presence on the court is definitely enhanced!

Since working with Referee Advantage, I have found a new love for weight training. I used to go to the gym just for cardio but now I love going to the gym to get a good pump in and do my cardio as well.

If you’re someone who is on the fence, I highly recommend you give Referee Advantage a try! They will listen to you and create a program specific to what you want to accomplish.

Jason

CEO, Entrepreneur

I initially started working with David because I had let myself go and was not happy with how I looked.

I wanted to take a “lazy approach” to fitness and only work out 3 days per week for 1 hour because that’s all my schedule would allow.

I couldn’t believe what happened after just 8 weeks. I looked like a completely new person and I am now the strongest I have ever been in my life!

Robert

High School Basketball, Retired School Principal

Before starting my program, I was stagnant, and minor aches and pains just wouldn’t resolve themselves. I worked out 4-5 times a week, but 20-30 minutes of cardio and a weight circuit twice a week weren’t doing it for me, and in December I could already feel myself wearing down.

Kara

Life before Training with RefereeAdvantage consisted of endless steady state cardio and weightlifting to “tone”. Since working with David, I have tracked ALL of my reps and sets and weight increases and have seen some major improvements. Another major shift I have seen is in how my clothes fit. I have lost over 10 inches collectively, mostly in my thighs and hips, and couldn’t be happier.

The biggest benefit I have seen since training with David Zetts is how I feel on the court. Not only do I feel confident in how I look, but more importantly, I feel ready for anything. My Transition speed is definitely improved, and I only have David to thank for that. I also feel like I have so much time back in my day because I am actually spending less time working out to get the results I have been looking for.

If you are thinking about starting training I have two tips for you: 1.Trust the process and 2. Put the scale away. The best thing I have done in all of this is trusted David. At the beginning it was really hard to walk away from what I “knew” about fitness and trust that his method would get me the results I was looking for in much less time and much fewer miles.

Ultimately, I couldn’t be happier with my results so far and can’t wait to see what David has in store for me in the future!

Tayson

High School Basketball

When my gyms shut down due to COVID-19, I reached out to David to build me a plan that I could follow from home.

I am completely blown away with my results, especially considering the fact that the program is just 3 days per week of training. David met me right where I was in terms of my experience and fitness levels and took me to a whole new level.

My goal was to gain muscle, which has always been difficult for me to do.

In a matter of 8 weeks, I had already gained 10 lbs of muscle. It has now been 3 months and I have gained 15 lbs of muscle and couldn’t be more pleased with what I have learned and experienced.

Jeff

Before starting Referee Advantage, I was in a place in my life (health wise) where I knew I needed to make positive change. This change included losing 20 plus pounds, maintaining that weight, getting stronger, developing good health habits, and being consistent in my efforts.

After partnering with Dave Zetts, one shift that I implemented was commiting to consistent training and better (but not perfect) nutrition.

One thing that was unexpected was the level of enjoyment that I would experience working through the different stages of my exercises programs. It was not the chore that I thought it would be. The positive results were a pleasant surprise in terms of how quickly they came and how well I looked.

My life (thanks to God) in terms of work, family and health was great then and is still great but has the added benefit of consistency, encouragement and support in achieving my health goals.

I encourage others to partner with Dave in achieving their goals. He treats you as the individual that you are, he is very encouraging (never condescending) and applies his technical knowledge and people skills deftly in working with you.
