Or not trying at all!

Look, you at least need to attempt to keep up. After all, we're not judging anyone for doing girl pushups instead of full fledged ones because we're right there with you! Do variations and modifications as needed because New York fitness classes are notoriously hard. However, if you are not even breaking a sweat and look over at me like, "Haha this is so hard I'm not even gonna try!" I'm gonna get annoyed. It's one thing if you're sick (or even hungover) so you're pacing yourself, but if you're making a joke out of the entire thing, it's just like, "Why are you here? There's people who couldn't even make the waitlist who would actually put in effort!"
