are there any advantages to higher rep sets with a *relatively* heavy weight? Let's say you want to adopt an HIT style training program, 1 set to failure with possibly rest/pausing techniques. Here's an example, say you can do 3 sets in the 4-6 rep range with 265 on the bench press. Now if you go for the one all out set with rest/pause you may get 5 reps, pause, 2 reps, pause, 1 rep for a total of 8 reps.
Now, say instead you lower the weight relatively, to about 225 and now can do 10 reps, pause, 6 reps, pause, 3 reps for a total of 19. DC training says once you rest pause a certain number of total reps, you up the weight, so say 20 is your target, then the next workout you can up the weight to 230 and start over.
Obviously the second example is a higher rep set, but still at a decent weight relative to the max you can do. Is it more beneficial to do those 19 total reps to failure with the slightly lower weight, or just knock yourself silly and always go for the higher weights even if you are doing a lot less reps?
