A bouldering wall? Monkey bars? Pilates classes? Yes, that’s at your hotel.

Not long ago, the average hotel fitness center amounted to a few treadmills, a couple of elliptical machines, free weights and a television tuned to ESPN.

That’s not good enough in 2015.

With an increased appetite among consumers for fitness — and an increased urgency for hotels to differentiate themselves for a new generation of traveler — the concept of fitness on the road is in the midst of a revolution that reaches from stylish boutiques to the mega-chains.

The presence of hotel fitness centers is believed to be at an all-time high. According to industry trade group the American Hotel and Lodging Association, 84 percent of American hotels had a fitness center in 2014, up from 63 percent in 2004.

For many, offering basic exercise equipment is no longer sufficient.

On the boutique level, Kimpton’s Alexis hotel in Seattle doubled the square footage of its exercise areas this summer by adding what the hotel’s general manager, Jenne Neptune, described as a “functional fitness room.” Created with input from a nearby CrossFit gym, the space includes a rock-climbing wall, monkey bars and hula hoops. The more traditional cardio equipment — a treadmill, an elliptical machine and a stationary bike — sits in a separate room.

The next phase of the renovation will include video workouts for using the more creative equipment, Neptune said.
