If you’ve ever suffered an injury or have chronic joint pain, you know how hard it is to find a workout that won’t exacerbate the issue or hurt you all over again, especially if you’d like to get your heart rate up. We searched high and low, and talked to a few experts to find a few low-impact classes that don’t put an immense amount of stress on your joints, but will still make you sweat and allow you to rip all the weight-losing and strengthening benefits of cardio without leaving you limping to the nearest pharmacy for a bottle of ibuprofen. But don’t be fooled — low-impact doesn’t mean low-intensity. When we say these classes will make you sweat, we mean it. See for yourself!
