On the other hand, although hard rock has an appropriate speed of rhythm, some hard rock appears to destroy the symmetry between the cerebral hemispheres and induce alarm, causing performance to decrease, possibly because of irregular beats and shrill frequencies. And weight training differs from rhythmic aerobic exercise in that it is not so dependent on a fast pace—performance seems to benefit from medium tempo music coupled with inspirational lyrics.
