Hi Lynn,
I've personally tried Cindy C, Michele, Bong and Pauline's classes only. All are my own personal opinions only, hope i don't get flamed by their supporters here..
Cindy C - too boring n slow for me, din manage to sweat, but she's got lots of years of experience and she's got her fans.
michele - she's good, but I got scared during my 1st time in her class cos i thot she was abit stern, been thinking about going to her class again..
Bong - v enjoyable workouts everytime cos it's not monotonous n dun make me feel like it's a chore exercising, will come back with aches n pains sometimes.
Pauline - love her classes cos she works us quite tough lol, sweat like dripping tap, but my knees couldn't take the repeated up n down non-stop bending. Would love to be able to continue with her classes weekly tho, but my knees keep giving me prob week after week. Couldn't move my body the next day as in sore, but the feeling's good cos u know u are working ur muscles, def worth it.
There's also Jasmine on Fridays, she's quite tough too, can sweat, v good..
Haven't tried the other instructors for weekends - Rasol n Jovalene - cos they are off days for my body
