Sometimes the hardest part about staying fit isn’t getting motivated or finding the right sports bra, it’s making the time to exercise. We’ve rounded up the best quickie classes in the Boston area, online resources, and customizable apps to help you work in your workouts.

If you’re not a self-motivator, exercise classes are key. Working out with a group in a guided setting is a great way to make sure you’re actually burning calories and not just half-heartedly striking yoga poses in between e-mails.

You also don’t have to sign up for classes in advance, so there’s no penalty if you plan to come and then can’t make it.
