10-to-1

10-to-1 is reps rounds where the first round is 10 reps, the second round is 9 reps, and so on dropping down to the last round containing 1 rep.  If there are multiple exercises you should complete each of the exercises per the reps in that round, before dropping down to the next next rep round and repeating each of the exercises per the reps in that next round, and so on.
