Isometric Challenge 3 Minute With A 20 Weight Vest

Johnny Grube doing a 3 minute Isometric exercise using a 20 lb
weight vest.

Hold pushup position for 1 minute.

Lower to a midway pushup position and hold for 1 minute.

Push back up and hold one minute.

I struggled with the extra 20 lbs but it was still a great short workout.
