I've been doing squats and DLs for years but this is the first video I have ever done. In the past two workouts where I have done squats and DLs, I have been left with lower back pain that seems unusual. The pain is not like the usual muscle soreness but instead, feels like some pain stemming from the spine.

During these two past workouts, I deadlifted a personal best 385 lbs so I am wondering whether this is simply too heavy for me right now and/or whether my form is off.

I posted a video of my squat as well.

Thanks in advance. And sorry for the quality - I had to use a cell phone camera and my basement has pretty poor lighting. If necessary, next time I will ask a friend to bring their digital camera for higher quality.
