The 9Round Difference


We know that time is money. That's why the convenience of a circuit is so important. You start your workout whenever you want - morning, afternoon, or evening. Each of the 9 rounds are different, challenging, and fun. From learning how to jump rope to hitting the speed bag, you will never get bored. The 30 minutes will be over before you know it.

Our members can't stop saying, "This is the Best workout I have ever had." That's because you will work every muscle in your body simultaneously, with no complicated machines or silly aerobic routines.

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.

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.

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!

Heart Rate Technologies

9Round takes your workout and fitness to the next level with the most advanced heart rate training program in the world. Keeping your heart rate in the correct "FAT Burning Zone" is critical to getting the results you want. With our screens inside the clubs you will get instant feedback on whether you need to work harder or slow down. You will also receive MEP's for each minute you are in zone.

what are meps?

MYZONE Effort Points(MEPs) are a new metric for measuring physical activity. MEPs accumulate for every minute of activity that a user spends in the 5 effort(intensity) zones based on one's individual maximum heart rate. The more effort that is put in, the more MYZONE Effort points are earned.

Every user receives their own cloud based account where all activity is automatically uploaded acting as an online log book of all physical activity.
