Workout ideas - all you need is a kettlebell (or do you)

I posted a post workout image on instagram the other day. The workout was 500 kettlebell swings, but every 50 reps you do;
-10 press ups
-20 Body Weight Squats
-20 Butterfly sit Ups
Got a few questions about the workout so I thought id get them answered in a quick video and give some ideas for different scale options.
Hope its helpful!
