One thing I miss about really being able to push myself is designing fun, high intensity workouts for myself! Just to further torture myself, I made up one I wish I could do. I mean, I could do it, but my knee would be screaming at me later on!
Since I can't join in on the fun, I think you should! Grab your jump rope... or just pretend you have a jump rope... and get going!
Note: You can alter the number of reps for the exercises to fit your fitness needs!
