Beating Down the Wall: Mind over Body
First of all let me extend my best wishes to fellow contributor Chris aka Dr.Swoll, in his endeavor to complete the MS 150. It truly is worthy cause and your support is indeed very valuable to fund multiple sclerosis research. I started thinking about what it would take to complete 180 miles in the Texas hill country and one thing stood out above all the other things I could think about and that is having a strong mind.
There comes a point when all of us think we can not go anymore. Another step would kill us, turn of the pedal drain what little energy we have left, rep under the weight of a barbell. Well the truth is, you are thinking you can’t so how the hell could you possibly expect go any farther? No matter what you are doing, this point is what many of us like to call the wall.
Time stops, its a surreal moment actually, and you are given a choice. I mean this very literally — your body actually asks your mind if it wants it to go further even though it may hurt, even though our bodies think we are spent and have nothing left to give. Those of us with the courage to take the harder path will say no, I want you to keep on going; whatever happens after that I will deal with when the dust has settled.
I mean it is true isn’t it?

Being able to see the three main heads of the quadricep (the rectus femoris is kind of overlapped by the vastus intermedius so you cannot really see it) is definitely an ego boost, and it should be. It means you care about your functional physique and are not in the gym just for show. Working your legs often targets your transverse abdominals, the ab muscles that few people work and are responsible for sucking your stomach in and creating those Spartan like channels between each of the rectus abdominus heads (what we see as a six pack). Exercises like squats demolish everything from your lower back, to your trunk (abdominal region) and then of course every muscle that frames our legs. People will say, oh but squats can hurt me… So can this keyboard I am writing with.
There are two types of muscle fibers, fast-twitch and slow-twitch or TypeII and TypeI. Within the TypeII class there are fast-oxidative-glycolytic TypeIIa and fast-glycolytic TypeIIb fibers. Contrary to what some people believe, both exert the same amount of force, it is simply the rate at which they do so that varies. TypeIIb fibers, as their name implies, are primarily anaerobic by nature possessing larger stores of glycogen and the enzymes necessary for anaerobic respiration, meaning they operate without oxygen. Adding to their architecture they have few mitochondria, the primary structure that is utilized for aerobic respiration.
