Prone Thoracic Band Pull -Mid-back tightness

I just started the Thoracic stretch series and am having a heck of a time with the Prone Thoracic Band Pull. My mid-back is really tight and cramps up when I am doing the Prone Thoracic Band Pull, nearly immediately.

Is there anything I can do to make this area less of a problem? I perform all of the stretches earlier in the series before attempting any of the exercises on the stall bars, which I thought would loosen me up a bit for the band pulls, but to no avail.

Thanks!

Hi melissa, you can try to perform the inverted cat position in order to stretch a bit more the abs and chest.
