The good news is that you are getting
close to a 90 degree angle between the leg and knee. The bad news is that is looks like the angle of the leg press machine is between 30 and 45 degrees. Therefore, in reality, you are performing a motion similar to what I would call
1/4 squats or, at best, 1/2 parallel squats. The best news is that I doubt you have to worry about getting a hernia that way.
How about a video of your shrugs which is the other exercise you mentioned in another thread? Something tells me you may actually be performing half shrugs and not correctly squeezing at the top. Correct form at lower weights is better than incorrect form at higher weights for
hypertrophy. Maybe that has something to do with your not being satisfied with your HST results. I can get a heck of a burn by doing one set of 10-15 shrugs correctly with
no weight. That is how you know when your form is correct. Try it with your current form and no weight and then try it nice and slow with a two second squeeze at the top. In fact, to me to get the best form, I have do the shrugs with two steps; the first step I call a half shrug and is almost as high as I can go and the second step is to pull my shoulders in and up further and gain another 1/2 inch in shrug altitude. That second step is where 3/4 of the gains come from. 90% of lifters still have not figured that out yet and are still shrugging like they are pantomining "I don't know."
I noticed awkward form in your squat video also where you almost tipped over onto your nose. I think it might be wise to go back to light weights and practice your form and forget about PR's, hurting tendons, etc. Post some videos and let us help you out. That should be a much bigger help to you than arguing with us all the time when your form sucks. That may be part of the reason that you feel that certain exercises hit different muscles than they actually do when performed correctly and safely.
Don't take this as sarcastic criticism and blow a gasket. It is intended merely to help. Just plain ignoring it would be better than a defensive response, IMO.
