What are the most helpful exercises down the road to build strength?

Hi everyone! What are the most helpful exercises down the road to build strength? I’ve had ACL repair and scar tissue removal a year apart and my quad is taking much longer to strengthen.

I love doing all kinds of weighted squats and they helped me very well. But honestly, it’s very boring and not a functional movement, but leg extension, hamstring curls and leg presses (all single leg) do work to build basic muscle. Especially when you can’t squat heavy yet it’s a good way to still be able to go as heavy as possible and build muscle quite fast.

Did you have a quad graft? The location where the graft is taken from can take much longer to strengthen, no matter what exercises you use.

Going to incorporate more squats! I had an allograft
