10 Rounds of the following for time: 10 Pull-ups, 10 Ring Dips, 10 Air Squats, and 10 Sit-ups Workout

Still have a bit of this lingering sickness so breathing is difficult. Really takes it's toll on a workout like this. I did this one as Rx'd so feel pretty good about that. I also learned about the 'kipping-ring-dip' today to help as I started to fail. You basically bring your knees up to your chest aggressively when you reach the bottom of the dip to help 'kip' up to the top.

Not real satisfied with my time but hopefully, when health, I can improve this.
