this is my new favorite "finisher" or conditioning exercise to do at the end of my workout. Grab two 40LB dumbbells and do a set of 10 burpees as fast as you can without letting go of the DB's. Rest 60 seconds and repeat 3 or 4 more times.
Anyone else do these? If not you should give them a try! Anyone else have a favorite finisher/conditioning exercise like this that they'd like to share?
