Deadlift starting position changes after rep 1 (using app bar tracker)

Used the bar tracking on the app to check my deadlifts, turns out my starting position for the first rep is about an inch closer to my body compared to the successive reps.

Does this mean that my first starting position is inefficient and I should start the bar slightly further away like with the other reps OR maybe my body reverts to the bar being further away because that is actually the best position?

The set:

I would recommend stopping and resetting each rep. You only get your 1st lift on the platform!

Your knees are in the way on the way down. Try deadlifts with a slow eccentric or resetting after each rep as mentioned. Otherwise you only practice the first rep once.

Ahh I see yeh definitely looks like the bars goes around my knees on the way down! So this means that my first rep starting position is best and the 2nd/3rd reps are less efficient then? :)

I'll lower them slowly from now on and see if it makes a difference, I know it's going to make them harder though lol.

Hips are too high and shoulders too far in front of the bar. Sheiko recommends shoulders be no more than 2-3cm in front of the bar. Basically, you need more lats in your setup. Take the slackout and pull your chest up as hard as you can
