Ever wondered what it feels like to be truly invincible? In this video I' m putting my MASSIVE BICIPITAL PEAKS to the ultimate endurance test. I take a heavy hammer and rain down powerful, rhythmic strikes directly onto the muscle. No flinching. No weakness. Just the sound of cold metal bouncing off ROCK-HARD armor. I let my boyfriend take the hammer, ge strikes again and again, pouring every ounce of his energy into breaking me. But it’s a lost cause. He can't leave me any marks!
