Deadlift form check (sinking hip?)

[Henry Pucknell]

Hi All,

Cant seem to progress my deadlift past 232kg - training towards a powerlifting meet in February.

Volume Day 192kg x 5

Hips sink badly here

Intensity day 232.5kg x 1 attempt - fail

My analysis is I'm screwing up the final raising chest / feeling heavy in your hands step and sinking my hips (also as a result the back is not quite straight enough) - any tips for how I can avoid doing this would be appreciated, cheers

[Shiva Kaul]

You aren't breaking the floor because your low back is immediately losing extension. You need to breath in very hard right before you lift. Rip is saying that your 4" belt may be the problem, since it might give you false proprioceptive assurance at the start position, or pain bracing hard against it.

Also, even your volume lifts would get red lights in a competition. You need to finish your knee extension earlier.

[Matt James]

You're kicking the bar forward on every rep, even on the volume set. Are you cueing yourself to push the floor away at the start? Keep your hips stationary and focus on knee extension to initiate the movement. I also agree with your assessment that you need to get more extension in the upper back before the pull, especially as the set progresses.
