50kg bench press

I noticed that my elbows are moving forward (towards my legs) as I progress through the set, is this normal?

Some people squat with their butts tucking like that fine.Can someone check my lower back on this please:
I agree though, I do sometimes end up leaning too far forward and it puts some pressure on the lumbar because of it while I stop myself from falling over
Happened today on one of my sets.

Feels OK..but looks pretty crap to me :/
Your back looks good to me, no rounding, as the weight is heavy your leaning forwards a little more to get out of the hole, and your butt is coming up first. I get this as well, and it's a case of really focusing on chest up, sitting back in to the squat and driving out of the hole, and engaging the glutes![]()
Nice squats Delvis! Despite there not being a lot of movement in your back, you are definitely tending towards flexing your spine. Knowing your issues, I bet this is a case of getting your glutes working properly. Spread the floor as you set up, and screw your feet into the ground (knees out!) for the duration of the rep, ESPECIALLY at the bottom.
Think I need a couple more pointers 
Delvis...i would say you need to put all your weight on your heels, keep it on your heals and push from your heals. The minute weight goes on your toes, the weight can and will come forward which is giving you the forward movements, making it harder. If you doing it properly..you can just about raise your toes off the ground and still squat. It should perrty much be a straight up and down movement. Try it without weights..or even just bar for a bit.
Just a matter of keeping it in mind I guess and everything tight as hell. Thank you
