Vice President Joe Biden works on strengthening his groping arm [Vine]

First lady Michelle Obama has been celebrating the five-year anniversary of her #LetsMove fitness initiative by challenging celebrities and others to #GimmeFive and pass along the challenge. Today it was Vice President Joe Biden’s turn to do Mrs. Obama’s bidding.

In this rare bit of video, both of Biden’s hands are in plain sight, which is reassuring. Maybe this is his way of keeping his “touching issues” in check.

A million arm curls ✓
Calls with world leaders ✓

Joe Biden: the entire world's old man we call "uncle" who isn't really an uncle. Just a fun weird dude.

A million curls a day is pretty inspiring. Would anyone else like to volunteer for the #GimmeFive challenge?
