Residents at The Astor condos on the Upper West Side will have no problem following Newton’s First Law of Motion, which states that an object in motion stays in motion. The Astor has its own state-of-the-art fitness center, and there are also an assortment of niche gyms and organized outdoor classes in the area, as well as enough running and biking trails nearby to satisfy an Ironman.

Here are some of our favorite fitness locations on the Upper West Side:

The Astor Fitness Center

The Astor’s fitness studio is a large, open space with high-end cardio, stretching, conditioning and weight-training equipment. One wall has a mounted barre as well as a full-size mirror and an area for dynamic stretching, yoga and ab-work. When it comes to fitness, convenience is king - and it doesn’t get more convenient than this.

SoulCycle | 350 Amsterdam Avenue

In terms of cycling gyms, SoulCycle has been in a league of its own for over a decade, creating a spin revolution that has taken New York by storm. The secret to SoulCycle’s success is the quality of its instructors, who create classes that are inspiring, tiring, and incredibly fun. It’s hard to fully explain the infectious, collective atmosphere, but there’s an energy at work here that everyone benefits from and creates. It’s a serious workout. You will feel it. But in the end, you’ll be glad you did it. More information can be found here.

Physique 57 | 2109 Broadway

For something a bit different, Physique 57 offers barre, dance, and strength-building workouts. The classes here blend ballet and dance training with weight and flexibility work. For someone stuck on a frustrating fitness plateau, Physique 57 could be just the thing to reboot the system. Moreover, classes are streamed online, so if you can’t make it to the studio, you can train in the comfort of your own home. More information can be found here.

Equinox | 344 Amsterdam Avenue

Equinox is one of the best fitness centers in the city. Not only is the gym itself stocked with pretty much every state-of-the-art machine and training module in existence, but its many classes offer an array of alternatives to the basic gym visit. There’s a boxing studio, a cycling studio, yoga and pilates rooms as well as barre, rowing and ropes classes. More information can be found here.

Central Park

Central Park is only three blocks from The Astor and hosts an array of yoga, pilates and bootcamp classes on a weekly basis. In the spring and summer especially, working out under the sun is always the preferred option, so walking over to the park should be a no-brainer. Moreover, there are a wide assortment or running groups, (check the New York Road Runners site for details,) as well as cycling groups and organized rides (check the New York Cycle Club site) for all levels. And, if you’d prefer to go it alone, it’s a stellar place to jog and bike.

Riverside Park

Central Park may get most of the attention, but for those who seek solitude, Riverside Park is a veritable paradise. With meandering, wooded running trails, fields and courts, and a bicycle-friendly boulevard beneath a canopy of majestic trees, the hardest thing about cardio in Riverside Park is not stopping to smell the roses. Riverside Park might just be the best run or ride in New York City, and it’s minutes from The Astor.
