Good morning on this bright and warming Tuesday.

New Yorkers faltering on their resolutions to get in shape this year have at least one good excuse: It can be very expensive.

In a city where a gym membership can cost hundreds of dollars a month, and where cycling, yoga and training classes are regularly priced at over $30 per session, breaking a sweat often feels more like breaking the bank.

But there are plenty of ways to get fit for free, so long as you know where to look.

Athletic wear stores. Brands like Athleta and Lululemon offer in-store classes in yoga, Pilates, boot camp, barre and more. If assuming a lotus pose while surrounded by merchandise throws off your chi, center yourself with a reminder that these classes are free — as long as you don’t shop on your way out.

Shape Up NYC. Maybe you avoid working out because you think it’s just … so … boring. In that case, you might try bringing a friend who makes you laugh to one of the more unusual Shape Up NYC classes offered by the parks department, like belly dancing, hip-hop aerobics or line dancing. The parks department offers 250 classes a week in every borough, all free. Still not enough mental stimulation? Try a bilingual yoga class and learn how to do a perro invertido.
