(KEYC) - New state COVID-19 regulations go into effect this weekend. Starting Saturday, gyms in Minnesota can reopen at 25 percent capacity or have up to 100 people inside at a time. The new regulations mean gyms are open for the first time in four weeks. The biggest modification is that masks have to be worn at all times whether you are lifting weights, on the elliptical or running on the treadmill.
