Rob Gronkowski Goes Nuts While Leading Aerobics Class at 'Jerky Jam' Event

Rob Gronkowski's intensity while leading an aerobics class is exactly what you'd expect.

On Friday, the New England Patriots tight end donned a headset and did his best to get the blood pumping for a group of fans. They couldn't hang with him.

Gronkowski was heading the class as part of "Jerky Jamathon," which allowed 50 fans to work out with Tom Brady's favorite target on top of Tony C's, a Boston sports bar.

Here's hoping Gronk teaches this routine to his fellow Patriots.
