Want to know how ‘The Rock’ keeps his 21 inch guns so swole? He shared a portion of his workout on his Instagram page.
21 inch Gun salute. Hellish bicep ???????? finisher I love called 21's. 7 reps from the top going only half way down. 7 reps from the bottom going only halfway up. 7 full reps. And pushing past your pain threshold to squeeze out a few more extra reps is where success and magic happens. THANK YOU for making my #BendBoundariesCollection a very big success for #ProjectRock & @underarmour. AVAILABLE NOW at @dickssportinggoods and in my LINK UP TOP ☝????☝???? #DwayneJohnsonTraining
