Thanks for the recommend, but i'm pretty sure that my lower body tension is fine, but the middle part of the body stays somehow loose, even though i had tried to lock it. But still, i will apply your recommend on the next day and clip that.I would bring the gaze up a little and focus more on driving the chest through the press and not the head. You are a little loose and disconnected. Grab the floor with your feet and squeeze the glutes through the entire press movement.
On the snatch it looks like you’re over extending your lower back near the top of the snatch, remember the body mechanics should be similar to a swing. Try bracing your abs more at the top to prevent the lower back from over extending. On your presses is also looks like your allowing your lower back to over extend on the descent, again try bracing your abs more when pressing the KB. You’re doing doubles so that makes it harder to maintain proper form. The squat looks good.
