About the team

  • Hunter <span class="nick-name">"HKT"</span> Tydings
    Hunter "HKT" Tydings
    Hunter “HKT” Tydings is currently attending Arundel High School and will graduate in the 2019 class. He has played on the soccer team at the school since his freshman year, and overall likes the experience of a jam-packed schedule of balancing work, school, and some type of exercise. “I really like the family aspect of 9Round! It’s great since no matter how out of it you are, you always have the trainers and other members lifting you up and pushing you to be your best.”
  • Jack <span class="nick-name">"HAMMER"</span> Jackson
    Jack "HAMMER" Jackson
    Jack "HAMMER" Jackson is Co-Owner and Operator of 9Round Gambrills. He is a recently retired veteran who served over 24 years in the U.S. Army. Hammer has always participated in athletics as a youth and kept an active lifestyle during his soldiering time in the Army. “I’ve been in competitive sports all my life, and that continued when I enlisted in the Army. I joined my unit basketball, flag football and softball teams. Minor injuries have limited my participation, but I never lost my competitive, athletic drive. 9Round gives me the edge I need to stay active and remain fit and healthy. 9Round’s full body, 30-minute workouts with no class times and a trainer fill my urge to get back into a lead role in fitness and GET FIT, NEVER HIT!!!”
  • Angela <span class="nick-name">"Get Cho&#039; Life"</span> Jackson
    Angela "Get Cho' Life" Jackson
    Angela “Get Yo’ Life” Jackson is Co-Owner and Operator of 9Round Gambrills. She is a retired veteran who served over 22 years in the U.S. Army. Angela learned the benefits of maintaining a physical fitness regimen. Prior to that she had no interest in exercise. “I always made excuses as to why I couldn’t work out. Excuses like, “I’m not a morning person” or “I don’t have enough time in the day.” As I’ve gotten older I’ve come to the realization how important my overall health and fitness impacted the quality of my life. I was introduced to 9Round, and loved everything about it. From the Full body workouts in 30 minutes, to the No Class Times, and with a Trainer included. I look forward to helping you reach your fitness goals 9Rounds at a time.”
