I was thinking of cutting out leg extensions from my workout. I don't know if they are necessary if I'm doing squats and deads. I also heard that leg extensions puts a lot of pressure around your knees. I have recently had knee pain and it is finally going away. The pain was most likely due to squatting with improper form. I was just wondering if I do extensions would it be too much on my legs and be wise to cut them out and just focus on these three exercises, Squats, Deads, Calf raises. BTW I am trying to bulk.
