This is a great workout. I was able to pound it out while I was on the road recently, but you can do this pretty much anywhere. The basic workout is:
For time:
- 500-meter row (substitute 30 burpees if you don’t have access to a rower)
- 40 air squats
- 30 sit-ups
- 20 push-ups
- 10 pull-ups

Work on your form: you’re only cheating yourself by using poor form. You can use this workout as a benchmark, performing it every thirty or sixty days. You’ll have an idea if you are making progress.
Stay focussed on the goal of moving your body. No rower: burpees. No pull-up bar: skip it or switch it up for one-armed rows or another back exercise.
