I have just started adding KB snatch myself as a method of tempo based training due to the cold weather and a recent injury which meant no running.
This is one example of a recent circuit which when kept at a good aerobic was good. 8 sets in total of 30 seconds of right arm KB snatch 37lbs, 30 seconds rest, 30 seconds of box jumps to 24" with step downs, 30 sec rest, 30 seconds left arm KB snatch, 30 sec rest, 30 seconds of burpees. Each exercise kept at a steady 12-13 reps per 30 seconds.
