HOTWORX - Concord, NH

HOTWORX in Concord brings the infrared-workout format to New Hampshire’s capital.

The model puts a guided exercise session — yoga, pilates, cycling or isometrics — inside a heated infrared cabin, run from a video with no instructor present. Sessions last fifteen to thirty minutes and the unit is yours alone.

It is worth being clear about what is and is not established here. Heat acclimation produces real physiological adaptations, including plasma volume expansion that carries over to endurance performance. Claims about dramatically elevated calorie burn and detoxification are less well supported. And exercising at temperature places genuine cardiovascular demand on the body — medical advice first if you have blood pressure or heart concerns, and hydration matters considerably more than in a passive session.

Concord is a small capital, around forty-four thousand people, with a gold-domed State House that has been in continuous legislative use longer than any other in the country. The Merrimack runs through it.

Studios operate on membership with 24-hour access and app-based booking. Concord sits at the junction of I-89 and I-93.
