    If you are ready for an awesome workout, come on down to 9Round Nashua! I have nothing but passion and excitement for the 9Round fitness model, you may even catch me doing the workout with you! I have had a longtime passion for fitness and people, with many years of customer service experience, and well over 1000 miles on my road bicycle. If you were to find me on a day off, I'd be sitting on the couch with a craft beer in one hand and an Xbox controller in the other. See you soon!

    Fitness has been an important part of my life and I am grateful that I get to share it with others and empower them along their journeys through 9round. I enjoy other activities such as running and yoga but my 9Round workouts are always the most fun. Even my daughter has fun working out with me! I have been at 9Round since August 2016. The community is much like a family and I have met some of my closest friends through 9Round. I'm always down for a partner workout or a game night (with wine of course), just ask!

Member Reviews

  • I came to 9round because I can never make a "regularly scheduled" class, but I need the motivation of working out with other people. I got a lot more than I bargained for! The 9round trainers are awesome and motivating, and I've realized how much I need these workouts and how much more in shape I *could* be. I love how every week there is a new CHOW, and every day there are new challenges. You can't get bored with this! If you love a challenge, this is for you :)

  • Love the convenience of being able walk in at any point and not have to wait for a class or be on a trainers schedule. Just jump right in and get a great 30 min workout. The heart rate monitoring is awesome as well. No guessing as to whether or not you are pushing yourself enough the system shows you and the staff. I burn 600 cal(140 meps) every visit.

  • Great gym, the staff is very helpful and enthusiastic, and they care about the people that come into the gym. The workouts are challenging but fun and you feel great afterwards!

  • I've never been a person who enjoyed working out, but I knew I needed to start doing something to better myself. I met Michele at a bridal expo and she explained the concept and signed me up for a free class. It kicked my butt and I realized how out of shape I really was, but I decided to stick it out. I've been a member for about 2 months and I can honestly say I look forward to going to the gym. All of the trainers welcome you by name as soon as you walk in. They boost your self esteem and help you prove to yourself that you can do it no matter where you're at with your fitness journey.

  • Joining 9Round was the best decision I made. I have tried other gyms but always got bored with building up my own routine or waiting for a particular class to start. 9Round offers a 30 minute workout that can be started anytime you arrive and varies every day. I find it challenging and rewarding.

  • I started at 9Round after getting tired of a boring work out at Planet Fitness. I am only on my 3rd month however I am glad I joined. The staff at my local gym are fun and very motivating.
