30. High Knees
Running in place is one thing, but the way to really get your heart going is to do high kicks. Think of it like running upstairs without there being any stairs. It’s a great way to get some cardio in if you don’t have any gym equipment in your home, so you’ll definitely feel the burn with this exercise. Run in place, but aim to bring your knees up to your hip level. That is until they’re almost at a 90-degree angle. Also, pump your arms like you’re sprinting, with your elbows at a 90-degree angle. It’s good to start slow and then increase your pace to a comfortable speed.
