Those familiar with the clever Sesame Street sendups of disco and country music may be disappointed by Exercise!, a fairly straight aerobic dancing record. Big Bird is charged with the uninspiring task of calling out exercise directions to music that is far less interesting than the usual run-of-the-gym aerobics numbers. There are a couple of nice flashes, such as Games Monsters Play, on which Grover and Herry Monster sing, "Flap your wings like this/ Flap them once again/ Oh! You don't have wings/ Flap your elbows then." But the record seems drab, especially compared to the disc of their cousin Miss Piggy. The Divine Miss P's LP is hilarious. She devotes one track to exercises that can be done with stereo controls—changing the balance, switching from bass to treble, varying the volume. On another, Snackcercise, she tells how to daintily grasp a jelly roll between thumb and forefinger and how to take a bite. Then she chants, "Chew it, chew it, chew it, chew it/ Swallow; deep breath; take a bite and chew, chew, chew, chew/ Swallow and finger lick." There are also cuts on lifting your frog, exercising your rights ("Jump up and down and scream"), losing weight by dancing in your dreams and by talking on the phone, sitting down or fixing your hair. Written by Sesame Street veteran Joe Raposo and National Lampoon co-founder Henry Beard, the album is musically sharp, too, and more than suitable for a dancercize change of pace. To quote Herself, it is "Trés good."
