Russian Dips Form Check

Please take a look at my attempt to perform the Russian Dip.  A few weeks ago I was unable to move my body up from the bottom position completely. I can know do what can be seen in the link below. I know I have tight shoulders and need to work on my shoulder extensions.  Any feedback on form or tips to improve is greatly appreciated.

I'm 6'5" 220lbs so space is tight as you can see

Hi CHad,, your execution shows the 2 major and most common mistakes:

1) shoulders are not aligned, i mean that shoulder should be placed in line with the elbows.

2) shoulder must be higher than pbars when you reach on the upper arms; you are falling under the bar.
