Got a question. When we do an exercise for example the bench press, do we need to extend the arm until it lock at the end or not ? Same goes to squat, do we lock at the end of the move or not. Get what I mean ?
In powerlifting, a lift isn't counted, until you lockout. Also in weightlifting, a jerk doesn't count till you lockout. In bodybuilding.....hmmm...here's where it's a little different. I'll list it;
Lockout:
-You work your whole tricep heads
-It looks better
-You strengthen your shoulders and joints and ligaments +isometric strength
No lockout:-Your muscles work harder with more lactic acid buildup
-More tear, probably more muscular development
In the squats, if it's light, don't lock out. If it's heavy and you wanna get stronger, lockout. This "rest" period helps you get more weights moved.
SO you choose what you want.
