Level 5: This one does not require much space. You will need to have room to get down and do a crab walk next to your desk. There is a lot of up and down off the floor in this one. Give it a try! Leave a comment how hard it is for you on a scale of 1-10 (10 is the hardest & you could not do it.)
We use the chair as a tool in this workout to work the legs and get the heart moving. I go pretty fast in these workouts so please go at your own pace. If you don't get in as many reps as i do that is OK.
