So what is the flaw with many exercise programs?  They assume that you can do certain things.  Not to name any names (“Letter”90″X”), but the first workout is a bunch of pull-ups and push-ups.  Great body weight exercises that you all know that I LOVE.  But who’s to say that the person staring at the screen can even DO one, much less properly and well.  Why do hundreds of people get hurt working out each and every year?  Lack of starting strength.  But what is “starting strength?”  Starting strength is being able to perform basic mechanical movements.  And being able to do so without muscular compensations that show altered joint movement patterns (arthrokinematics).  Do your knees dive in when you squat?  Does your head drop when you do a push-up?  These are just a couple of examples of dozens of altered arthrokinematic patterns.  So what?  What’s the worst that can happen?  I keep telling you that you need to stay active.  Now, I’m going to be picky about how you do it?  Darn right I am!  What happens is that your body gets used to moving in an altered movement pattern.  Using muscles that aren’t necessarily supposed to be used for that job.  The strong get stronger and the weak get weaker.  Ultimately leading to pain and/or injury in the long run.  Any thoughts on how to fix it?  Work with a qualified, experienced fitness professional.  I know it sounds like I’m just beating the drum, but start to pay attention to your body.  I mean REALLY pay attention and watch yourself move.  See if what you’re doing looks the way that it’s supposed to.  And if you don’t know what it’s supposed to look like in the first place, that should be your first clue.  Now, once you’ve developed your foundation, THEN you can go on to all the hard stuff.  All the fun stuff.  But you want and NEED to make sure that your body is moving properly in the first place.  Your workouts will thank you!
