I currently only do heavy compound movements for legs, but since most of the successful lifters here advocate the inclusion of isolation exercises after compound movements I thought of adding leg extensions and leg curls to the end of my leg routine. However, I have read that leg extensions are bad for the knee.
Have any of you who have used leg extensions ever had any knee problems because of it? Is it a good exercise when the goal is muscular hypertrophy? I would like to get the opinions of those who have been at this long enough to have good results (BW > 200lbs).
Thanks in advance.
