I never found much use for speed days in bench (ie. 50% max for 3 reps). What is your take? Do you incorporate sets like this? Where do you find these sets to be useful?
When I did speed days, I would explode pushing the weight up, but I never did the "3 reps as fast as possible" move for fear of injury. I would always fully lock out each rep and hold the lockout for a second.
For clarification, I am not talking about a light day and a heavy day, but specifically the light/explosive triples commonly referred to on speed day.
What are your thoughts in general on the practice?
