Do me a favor and pick one of these videos that shows the problem.
Hey Tom,
I continue my journey against knee travel here (link to 1st thread).
As you suggested in the last post of the 1st thread I pushed my knees more forward, which resulted in a new problem I stayed at 75 kg at the moment, because I recognise that the weight is also getting an issue and I don't think I will get better form when I also add more weight to the bar.
I have the videos of my workout sets of 02/12/2015
First set 75 kg
Second set 75 kg
Third set 75 kg
I see that the knees get more forward but are now traveling backward and than are getting forward again like a zig zag line. What's going on now?
The sets of 02/14/2015 are showing the same behaviour:
First set 75kg
Second set 75kg
Thrid set 75kg
Maybe it's getting even worse especially in the first set. I also lack depth.
After that I had a little break due to a business trip and did three more sets with 75 kg on 02/19/2015
First set 75kg
Second set 75kg
Third set 75kg
I think the first set isn't to shabby on rep 1/2/4, don't know why it's a bit better there and also in set 2 except for the last rep but set No. 3 isn't good at all.
I apologise for the short distance of the camera but there was not enough space to position the camera on that day. I also had to change the sound of set 2 and 3 because youtube blocked the videos probably because of the background music in the gym.

I don't know why your knees are going back mid-way through aside from the obvious one. You are letting them go back. Don't do that. Get them out front and keep them there. It might be that simple.
OK, I thought there may be an obvious geometrical error like "chest still to high" or something like that.
I have a video here from the third set of my last workout.

I see that Rep 3-5 are having still the same problem. But in 1&2 I only saw it with slow motion. Is this a tolerable amount and what I should aim for on every rep or still too much?
