Not only does a Spin class benefit your muscles—everything from your
legs to your core—but it’s also a great
low-impact cardiovascular workout,
which improves your blood flow, increases your stamina, boosts your
mood, and prevents against chronic issues such as
high blood pressure, heart disease, stroke, and diabetes,
according to Mayo Clinic. And because of this intense cardio workout,
you’ll burn a ton of calories, too.
While King says the average is about
400 to 600 calories per class, she’s seen some
riders burn more if they’re going particularly hard and long. Some
indoor cycling classes even incorporate the use of hand weights to
“promote upper-body work, since cycling is a predominantly lower-body
workout,” Atkins adds. So in one 45-minute session, you can challenge
your upper body, lower body, and core.
