Turns out these workouts are making me a bit stronger. Not Superman or Stretch Armstrong, yet. But strong enough for me to be vain. Case in point: I am sitting in my boss's office during a meeting. My arm is stretched out over the top of the couch where I sit. My arm is slightly twisted back, causing my tricep to face me. Midway through the meeting, I notice it. And I flex it. And there is an unfamiliar bump there. I flex it a couple more times - hey, that's my muscle! I poke it. It's definitely stronger.
And then I realize I am still in a meeting. And it's not a meeting about my triceps, so I should probably pay attention. But later on my lunch break, I knocked out 60 pushups, just to make sure the the muscle-bump doesn't go anywhere. It's growing on me.
Mark Sisson claims that one of the side effects of going primal is something called LGN - Look Good Naked. Well, I can't speak for the rest of my body, but these arms will be in short-sleeves for the summer.
