@jrich_02: “Grave Diggers” are an unconventional strength & conditioning exercises that will get almost every muscle groups fired up and working. Grab a heavy dumbbell and see how fast you can move it! Exercises don’t have to be familiar to work. Give these two dumbbell movements a go and build some brute strength. #fullbodyworkout #functionaltraining #unconventionaltraining #jrich02 #strengthandconditioning
