Carried the 27.5lb blob I bought home, filed the rust off, and chalked it up:

Load block to bench: 4x5/5x27.5lbs

Followed that up with dexterity balls and finger extensions.  Mixed a couple moderate gripper closes in there.  Then I stretched my calves, foam rollered my upper spine, and stretched my posterior shoulder capsule.  I'll probably stretch my neck after I shower.  Not the best grip workout, but time was short.
