How many sets does everyone do for negs then. I've done negatives three times and found three sets too much, causing near injury and worry over joints. The last two times i've done negatives it's been a constant two sets with an increasing load (weight/resistance) between workouts if i feel the weight too manageable. I also do only 5 or, if i can manage it, 6 reps at a set weight with the intention to use the same weight for 6 sessions (two weeks).
