Why kettlebells kick your butt

 Yesterday's training sesh needed to be abbreviated to allow time for a new client assessment, so I cranked out a quick 12 minute workout with a single 16kg kettlebell.

Here is the workout:
Ascending ladder style with a switch between starting on the next rung. Did 1 rep of the clean, press, squat, snatch, then switched hands and did one rep on the other side. Then went to 2, then 3, and so on, up to 5 before starting over.

Total reps performed in 12 minutes:
Clean x30ea
Press x30ea
Squat x30ea
Snatch x30ea
