John Hanlon on the Athletic Edge squat macine at WST.
Isolation exercises are not "bad" to do and using a few of them can be a good ADDITION to your program. Don't get carried away with them, but a set of thick bar curls added to the program or leg curls AFTER SQUATS ARE DONE is ok.
I believe that the CORE foundation of your program should be the big basic compound exercises. That, however, does not mean that you should NEVER do ANY of the isolation exercises. As long as you are not looking for the easy way out and substituting the isolation exercises for the much harder multi joint lifts, using a few of them in addition to your program can be beneficial.
