Samson and his team are amazing humans. I came here to train during my vacation to Hawaii. They all made me feel like I was a part of their team, real coaching and sportsmanship is found here. The hard work was put in and there’s no doubt about that. I’ll never forget how hard they pushed the cardio conditioning and drilled how important it is for the sport of boxing. I will always keep Iron Kingz Boxing in my heart and look forward to returning back to Hawaii to specifically train HERE. If you want good quality boxing work in Honolulu it’s here at Iron kingz with Coach Samson and his fighters. Mahalo!

Happy New Yeatr 2026. Came here with little to no experience for our 9 year old son, Kaleo. Coach Samson’s training sessions are intense , fun, and always takes the time understanding my son’s capabilities, baby steps. My son in a short time has developed a lifestyle holding himself accountable to school work, grades, and the importance of boxing and it’s been a motivation to show up and train because of Coach Samson. We found a Sensei, Coach, Trainer that understands the keiki’s and teaches not only boxing but education, success, survival, health. Coach Samson is more than someone who yells instructions from the ring. He is an exceptional coach, one who molds raw talent into a champion. I can foresee my son improving and highly recommend Iron Kingz. They have a great boxing coach that combines technical knowledge, emotional intelligence, and adaptability to unlock each member (kids) boxing true potential and they have a comfortable parents room upstairs with a/c so cozy and comfy and I’m able to watch my son from the huge TV’s without the distraction of my presence, while he is training. Bomb.com I look forward to see my sons progress same time I think it’s normal for a mom to feel afraid when he gets hit but it’s part of training lol. Sincerely, Over protective mom —James and Michelle
