So I set up for my bench press with my shoulder blades in tight, my back arched, on my toes with my feet behind my knees. But when I bench heavy, my right hip randomly tightens up and my form crumbles. The right side of the bar starts to go down and the spotter needs to help me.
Now, this only happens when I'm benching heavy so I'm assuming there's a weakness somewhere on my right side that's causing this. Any idea why this could be happening, and any potential solutions?
As a precaution, I've been foam rolling my IT band but I'm not too sure if this is the cause.
Any feedback is much appreciated!
