What athletes and families say about training the mind and the body with 90/10 Mentality.
Coach Hoelting has coached me for the past five years, and I'm so grateful for everything she has taught me. She has helped me become a stronger and more confident fielder while teaching me so many valuable skills along the way. I wouldn't be the fielder I am today without her guidance, support, and dedication! I'm so thankful to have had her as my coach!

Holly worked with my daughter as she got closer to transitioning to the high school level of softball, and we were so impressed with the experience. She was always positive and encouraging, while still challenging athletes to push themselves and get better. She did a great job building relationships with kids and making them feel comfortable while holding them accountable. Holly knew her stuff and was truly invested in helping young athletes grow—not only as softball players, but in their confidence and love for the game. We were so thankful for the time and effort she invested in our daughter!

Holly has really helped me to have a positive approach for my hitting. Her coaching tips have stuck with me over time, and I still use them to this day. I am always grateful for her dedication to help me succeed!

We've really loved watching both of our kids grow through their time at 90/10 Mentality. They've had the opportunity to experience such a wide variety of training, from hitting and baseball to speed and agility, and they've genuinely enjoyed all of it. It's been awesome to see not only how much their skills have improved, but how much their confidence has grown along with them. Coach Hoelting deserves a huge shoutout because she has the best way of cheering them on, giving them great feedback, and getting them excited about what they're learning. She knows how to challenge them while still making them feel confident and proud of their progress, and that has made such a difference for both of our kids. We also really appreciate having access to the batting cages with flexible hours. It gives us the opportunity to get extra reps in and put what they're learning in lessons and classes into practice on our own time. Having that flexibility has made a big difference for our family. We're so thankful to have a place like 90/10 where our kids can keep learning, improving, and building confidence while having fun with the game!

We first met Coach Holly eight weeks ago, and it's been such a joy to see my daughter grow. Hadley started out feeling a bit unsure of herself, and Coach Holly has been exactly the person she needed—someone who truly believes in her and guides her with care. Holly brings energy to every session along with corrections that are goal-based, which keep Hadley focused on improving. Together, they've built the basics that will help Hadley in softball for years to come. Whether she's practicing with her team, working one-on-one with Coach Holly at 90/10 in lessons or lab, playing catch at home, or hitting in the cage on her own, she's building on that foundation. Coach Holly has created a welcoming space where Hadley can work through both her skills on the field and her self-confidence.

I had the honor of playing softball at North Scott with Holly Hoelting as my head coach. Holly did an incredible job of building a team and preparing young girls not only physically, but mentally for the game. She always seemed to know exactly what I needed to hear, whether it was at practice, before a game, or in the middle of one when I needed an extra push. When I went on to play college softball at Marshalltown Community College, I honestly realized even more how important the mental side of the game is. I wish I would have had a coach in college who continued to develop that part of the game because I noticed my mental side really struggled without it. Looking back, I'm so grateful for what Holly taught me in high school because she showed me that softball is so much more than just the physical skills. The confidence, mindset, mental toughness, and preparation she taught us are things I still carry with me, and it made me really understand why 90/10 is so important — the game is 90% mental and 10% physical.

Our daughter has been working with Coach Holly for more than two years, and the progress she's made has been incredible. We've seen significant improvements in her power, confidence, and ability to make adjustments at the plate. Holly provides individualized drills that address her specific swing, along with practical swing cues that have been invaluable during games and tournaments. One thing that really stands out is how Holly has adapted her coaching as our daughter has grown and progressed. She has taught her not just how to make adjustments, but to recognize when they're needed and take ownership of the process. The expectations have grown along with her abilities, and Holly now challenges her to be intentional with every rep rather than simply going through the motions. Through 90/10, we also have access to the facility and tools needed to continue working outside of lessons. We've worked with Holly on fielding and baserunning as well, and her instruction has been excellent across the board. We highly recommend Coach Holly and 90/10 to any family looking to help their athlete develop their skills and reach their potential.

While Holly's experience as a Division One softball player, head coach for a premiere varsity program in the state of Iowa, and constant researcher of new drills and strategies separate her from many other coaches out there, it is her tremendous enthusiasm and ability to individualize her approach for each player that makes her the best! Our girls have built a love and bond with Coach Holly and the game of softball through the years due to her ability to connect with them! As our oldest enters junior high, Coach Holly is gradually transitioning to Coach Hoelting who still has the same enthusiasm and trusting relationship, but it has allowed her to push harder and prepare for the higher level competition she will be facing. We won the lottery having 90/10 Mentality and Holly Hoelting developing athletes and future contributing citizens in the Eldridge area!

We have been impressed with the softball fielding, pitching, and hitting lessons our daughters have received over the past years. Coach Hoelting tailors her individual instruction to each girl's age, skill level, and development, and we have seen noticeable improvement in both of them. She not only focuses on fundamentals and long-term development, she also focuses on building confidence while keeping them engaged and excited to learn. Her ability to challenge them while making lessons fun and encouraging truly sets her apart. Her passion for the game is contagious and it has only made our daughters drive even stronger.

My son has been a part of 90/10 Mentality for 2+ years. During that time, his growth as a player, teammate and student of the game has grown exponentially. Holly instills foundational skills that pave the way for continued improvement; always adjusting focal points to ensure she's getting the most out of each session. We're grateful that she's part of the North Scott community and look forward to continued success. Stacking days.
