Do you guys lift to failure every single workout?
I work out 3 times a week and I feel that I'm going to failure too often. Meaning that I lift weights that are heavy enough so as to leave my muscles completely spent after I've done my 3 sets of reps. Is this always the best technique, or would it be wise to only do that, say, once a week, and then lower the weights a tiny bit on the other two days and not lift to failure on those days? (I work out the same musclegroups twice a week).
Also, sometimes I even go beyond failure by utilizing dropsets after I've done all of my sets for a particular musclegroup. I know that this technique can be beneficial, but how much is it ok to do this? Is there a limit? I'm concerned that my body will get too used to the dropset technique and that it would want me to do dropsets every single time in order to make gains (if I do it too much).
