What is negative resistance in weight training?
Assuming you know what a Bench Press is, when you push up there is positive resistance. Say the bar ways 45 lbs and you have 55 lbs of weight plates then there is 100 lbs of positive resistance. When you let the bar down after you have pushed it up there is 100 lbs of negative resistance, because it is coming towards you, you are not working to push it up but rather to take it down.
