If you really want to see the fruits of your labor, try to lower your body closer to the ground before pushing yourself back up. I must have gotten at least two or three inches lower between Day 1 and Day 30—a true testament of my improved upper-body strength. Have a friend take pictures of your pushups day by day to see your progress, or peek in the mirror if you must (keep it brief—remember, you want a neutral spine). And keep working on getting lower until you literally run out of space. Boobs to the floor (though not on the floor), as I like to say.
