9Round works because it includes everything you need: a full-body workout that’s fast, effective and fun… personal trainers to help you… and expert nutritional guidance. And it’s all based on the latest exercise and nutritional science.

9Round Fitness Nashua NH Amherst Street is owned and operated by us, co-owners, husband and wife Michele and Joe Castellucci. Michele is the general manager and head trainer. Joe is the back office end of the business, but you will see him on the floor with Michele as well enjoying our members! Michele's experience in the fitness industry led us to find a way for people to fit in an effective workout in 30 minutes. One of the many perceived road blocks to enagaging in regular, intentional exercise is "I don't have time".  9Round adresses that belief along with many others! The full body workout 9Round delivers is effective due to the combination of aerobic, anaerobic, and resistance training. All too often a person's fitness routine is lacking one or more of these important components of total fitness which reults in frustration due to lack of results. More time than is necessary is spent trying to figure out how to get results. As a Certified Personal Trainer, Michele discovered most people enage in either cardiovascular exercise or resisitance exercise, not acheiving desired results, and in turn may look to a trainer to help them get out of the impossible cycle. 9Round specialized trainers are included in all of our memberships at a more affordable price than traditional, general practice personal trainers. Motivation and guidance is also a component frequently missing from a person's exericse session. At 9Round, there is ALWAYS a trainer present to insure proper form and execution of the exercises at each round and to motivate through the completion of the round. This is included in your membership investment! Have you ever been late for a fitness class so you didn't work out at all that day?! At 9Round, we only schedule your first workout! Members can get in their 9 rounds at any time during or operating hours! Flexibility is key!  We encourage you to call or contact us on the web to book your first workout! This is the best way to get an understanding for what 9Round will do for your health and fitness!

  • 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.

    "After learning how much fun the 9Round program is, I've tried to work out 3-4 times a week since then. Now, instead of big, old and tired, I feel strong, balanced, and focused. I thank 9Round for the energy, environment, and guidance for my transformation."

  • Angela H. loses 50 pounds
    "Joining 9Round has made me healthier, thinner, and it has made me feel better about myself. I have lost more than 50 lbs and gone down from size 18 to size 8. I also have more muscle than ever. I wouldn't have lost the weight and become healthier without the wonderful group of trainers at 9Round."
