I believe he's talking about Vince Gironda's training split. For example, the 10 rep set is performed with 50% of your max number, rest of "up to" 60 seconds is allowed then the 8 rep set is performed with 75% of the 6 rep max, rest up to 60 seconds and go with the 100% for 6 reps, finishing off with 15 reps at 35% of 6 rep max. For a bench 6 rep max of 200#, this would mean 10x100 8x150 6x200 15x70.
