HOTWORX Portsmouth is a locally owned boutique fitness studio bringing together 12 different virtually instructed infrared sauna workouts, 24/7 member access, and strength training outside the saunas. Come for Hot Pilates, explore Hot Yoga, or build variety into your week with short cardio sessions and resistance training.
Find us at 1465 Woodbury Avenue, Portsmouth, NH 03801, in Market Basket Plaza near Whole Foods Market. We welcome our Portsmouth and Seacoast neighbors with more ways to move and a team that wants to understand what matters to you.
Our Hot Pilates sessions offer a mat-based workout focused on core strength and controlled movement. Hot Yoga combines held yoga poses, balance work, and core exercises. Both are 30-minute, virtually instructed workouts inside an infrared sauna.
You can also explore Hot Barre None, Hot Bands, Hot Buns, Hot Core, Hot ISO, Hot Warrior, and Hot Stretch. With different formats to choose from, your routine does not have to revolve around the same workout every visit.
HOTWORX calls the combination of exercise, heat, and infrared energy “3D Training.” A virtual instructor guides each sauna session, so you can get familiar with the movements and explore the formats that interest you.
Ride with Hot Cycle, row with Hot Thunder, or work your upper and lower body on the total-body trainer in Hot Blast. These 15-minute sessions give you another way to fit movement into your day and complement your Pilates, yoga, or strength-training routine.
Our FX Zone offers free weights and functional training equipment outside the saunas. Members can use this area before, after, or between infrared sessions—bringing sauna workouts and additional strength training together in one studio.
With 24/7 member access, you can reserve sessions around your schedule. Whether you’re starting a new routine or adding variety to an established one, our team will help you explore how HOTWORX could fit your goals and your life.
