ok, maybe it's because i woke up not too long ago, but i'm confused at the description of today's tip.
first it says that if you raise your arms above parallel you'll bring in the traps... then to avoid that you should go from 45 degrees below parallel to 45 degree ABOVE parallel? but i thought going above parallel brings in the traps???
"Perfect Lateral Raises
Any lateral raising of the arms beyond parallel to the ground sees a sudden increase in upper trap involvement. This isn't bad in itself, but if you wanted to keep the tension on the delts and not give yourself a rest, you may want to reduce the range. To really isolate the optimal overload range of the delts during the lateral raise, reduce the range of the arm movement from about 45 degrees below arm parallel to about 45 degrees above arm parallel."
