Seven Events to Flex Your Competitive Muscles

How many workouts have you tried before you found a routine that finally stuck? We’ve all been there. You might remember the days of walking into your neighborhood big box gym and wandering around the various machines with no idea where to start – no direction on what combinations of workout machines will work in your body’s favor. You walk out feeling like you just wasted your time and money – two of life’s most prized possessions.

Key takeaway? Don’t settle on a fitness routine that doesn’t inspire you to change.

At Orangetheory Fitness, we take the guesswork out of exercise, and we also find ways to make your workouts anything but routine. With workout templates changing every day, and fun, engaging benchmark challenges strategically scheduled at different points in each calendar year, there are always new goals to set your mind to. And the only person you’re competing against is you. Constantly switching up the workout not only makes it more fun, but it helps challenge your body in new ways to ensure you never plateau. This day-to-day change will continuously change your body from the inside out. And that’s what will create results!

No matter what you’re looking for in a workout, you’re sure to find it at Orangetheory. We tailor every workout to your unique fitness abilities to ensure you always walk out of our studios feeling successful. But the best part is, you might discover your inner athlete with all of our events throughout the year. Whether you’ve set your sights on an upcoming 5K, are conditioning for a triathlon, or are just ready to up the intensity, every Orangetheory workout provides a foundation for more strength, more energy, and more LIFE.

Participation in the annual fitness events is not mandatory, but they’re a great way to quantify and track personal improvements over time. For example, how you performed during a 200M row in January versus a 200M row in April will be different with consistent attendance at OTF. For those of you looking to challenge yourselves or engage in a little friendly competition, consider participating in these annual (or semi-annual) events. The best part is, if you don’t want to compete, results are tracked via personal improvements in addition to a leaderboard. And again, they are for all fitness levels! 


  • Overview: Develop the groundwork for changing your lifestyle habits to start transforming your body at the cellular level.
  • Duration: 8 Weeks
  • Perfect For Members Who: Want to kick off their New Year’s resolutions on the right foot, and keep themselves accountable for the full duration of the challenge.
  • Why You’ll Love It: You have a systemized way of tracking your results each week, as you’re surrounded by a built-in support system cheering you on every step of the way. This helps keep you accountable to build a healthy habit and continue your fast track to more life.

  • Why You’ll Love It: The process of tracking your mileage encourages you to go all out on the treadmill, bike, or strider in class in hopes of achieving your marathon goal.

  • Why You’ll Love It: Orangetheory Fitness studios turn up the heat in the cool winter season by incorporating festive, holiday-inspired workouts. Let’s just say, we get a little creative.

  At Orangetheory Fitness, we’re not just a studio with static workout equipment. The coaches, the community vibe, the sweat, the music, and the technology all work together to enhance the experience for you every single day – an experience that’s always changing, an experience that never gets boring. It’s all about what you put into the workout that counts. In case you ever wanted to know, the Experience Development Team spends roughly 30 days and 900+ hours creating, testing, and editing 90+ unique workouts designed to challenge members of all fitness levels across 17 countries and 900+ studios.

It’s simple, really. Clint Eastwood said it best when he stated, “What you put into life is what you get out of it.” The vision of Orangetheory is no different: the more you put into the workout, the more you get out of life.    

For an intense full body workout that will get you on your way to the body you want, come into Orangetheory Fitness in Nashua, New Hampshire. With group training sessions led by personal gym trainers that are some of the best in the business, the Orangetheory workout is the most fun, yet effective, high-intensity interval training (HIIT) session you will ever experience.

Orangetheory Fitness group one-hour workouts are challenging, with intervals of strength training and cardio. Our personal trainers will lead you through a workout utilizing treadmill training, indoor rowing, TRX suspension training, weight training blocks, and floor exercises.

During Orangetheory sessions, you will wear a heart rate monitor to ensure that you are getting the most efficient burn. It gives real time results up on a video monitor for your trainer to see how you’re doing and helps to keep you accountable and give you that extra push. Our gym sessions have been designed to keep your heart rate within a targeted zone: 84% or higher of your maximum heart rate or zone 4/5 for at least 20 minutes of the workout. When you are able to do this, your metabolism is boosted and energy is increased. This results in the Orange Effect—extra energy and calories burned for a day and a half after your session has ended!

Whether you have a weight loss-based goal and are looking to tone up, or have a fitness-based goal and are looking to increase your endurance and build your strength and power, Orangetheory Fitness is the best studio in which to pursue your goals.

Orangetheory Fitness gives you many great choices by way of membership options, all with no gym contract required. Whether you prefer a pre-paid package or a monthly membership plan, there are different levels to choose from. And if you have family members in your household who also want to “go Orange,” be sure to ask about our family add-on discounts! Just go online or give us a call at (603) 882-6800 to book your first session with our Nashua, NH studio now! With your first session on us, you can easily take that first step to achieving your fitness aspirations.
