2 different routines not sure which one builds muscles?

[goca]

Ive been told that doing 3 sets and decreasing reps while adding weight will add muscles,

and doing 3 sets keeping reps and weight the same will tone?

this is for any muscle group!

Is any of this true?

Either completely not true or very very simplified - can't decide which.

Anyway just look around here and the weight training forum, there've been countless threads about people's bulking workouts and arguments about how many sets/reps to do.

I personally do 4 sets of 10 reps on whatever weight allows me to just do that before reaching failure, and 2-3 exercises per muscle group and 2-3 muscle groups per day.
