@_dylanharrigan: Most blokes treat leg extensions like a throwaway exercise at the end of leg day. Load it up, swing the weight, let the stack crash down, repeat. If you actually want to get something out of them, set yourself up properly and control the fucking rep. Seat back. Keep tension through the bottom. Pause just before the stack touches. Then drive back up with intent. Don’t just chase the squeeze at the top and completely throw away the lengthened position. Make the quad work through the whole rep. Save this and do it properly next leg day
