This will clear a couple of things up:
REST PAUSE
Lets say that you are performing incline presses and you are able to get 9 reps. . . .you rack the weight for 10 seconds. . . . after 10 seconds you unrack the weight and force out an additional 2 or 3 reps.
STATIC HOLDS (using incline presses as examples)
This is where you hold the bar (not in a locked out position) for as much as 15 to 30 seconds. You are resisting gravity with every thing you've got. You can perform these at the bottom (2 inches above your chest), middle, or 3/4 of the way before your lockout. It teaches you control.
