NORTH DAKOTA (KXNET) — It's hard to stay active when you're experiencing the full force of a North Dakota winter, but now, our state's Health and Human Services (HHS) is reminding us of a way we can stay fit this season. HHS says that through the CDC, North Dakotans can find free to low-cost workout classes online. They can be both live or prerecorded classes. And authorities say they're available on Youtube, Instagram, and more.
