I've seen a lot of guys at the gym lately that perform "partial reps" on all exercises. Their theory is that full range of motion puts strain on other muscles (in example: shoulder strain while bench pressing).
Which do you do and why?
I know there was a poll not too long ago...but I got to thinking about both sides of this question, and decided it'd be a good poll topic.
Personally I use full range of motion, I believe you get the most out of the exercise and so long as your stretch out properly beforehand there is little risk of injury.
