Geek P.O.D.: Range of Motion.
I saw this video of these two trainers trying to put up a "kickass crossfit" video of them doing handstand push-ups, push-ups and stair-climbers. But they barely move their elbows past 90 degrees and they are far from full extension in all their movements. So much for wanting to be kickass.
This brings me to today's Geek P.O.D.. How many of us actually perform our exercises in training to the full range of motion? Push-ups to the ground and up, chin-ups to chest and full extension of arms at the bottom. Things like these make you more creditable as a person who trains and gets more respect than doing half-reps in all your movements and thinking you can do heaps of that exercise and you are some king of the world.
