If you love to work out, you probably already know that the group fitness scene has been on the rise in recent years. With so many new classes cropping up—from spin to barre to yoga—studios like SoulCycle and PureBarre have become incredibly popular and developed cult followings. Unfortunately, many of these classes are also expensive, and can cost upwards of $40 per session (yikes).

The good news: For those of us who want a challenging workout without penny-pinching until our next paycheck, there are still studios, gyms, and retailers that have great fitness deals. Here, 14 that offer free or discounted opportunities to sweat for first-time clients.

First class discount

ClassPass (in 29 U.S. cities): This start-up charges members a flat monthly fee for access to classes at local studios (including popular spots like Flywheel, PureBarre, and Physique 57).

Regular ClassPass prices vary depending on location, but that same 5-class "Base" plan costs $75 in New York City, for example. 

Flywheel (in 16 U.S. cities/regions): The fitness studio (which offers both spin and barre classes) lets first-timers off a bit easy, slashing their regular prices by more than half. New clients can pay $15 for their first visit, then $34 on subsequent ones. 

SoulCycle (in 14 U.S. states/regions): SoulCycle offers a discounted class to clients who are new to the trendy spin studio. Pay $20 for your first visit, then $34 per drop-in class after that.
