Things I worked on today:
*Sprinting/LiftingA big thing I've decided to work on this year is cleaning up my clean/jerks/snatches...with a considerable focus on the specificity of the exercise and transfer to useful movement.
Today's focus was on
lifting as a means of transferring power in
sprinting.
In sprinting, some important mechanics to consider, coming out of start, are body angles for generating power(power angles) , and change of direction(which I will abbreviate COD from here out)of the body.
The problem with cleans that you see many of the times(such as the one posted right after this paragraph), is that there's no useful translation. There is many times over extension of the back, overuse of the traps, and no movement(well, lateral movement...but that's even worse for my purpose) of the LEGS. After all, the emulation of the clean is like moving your legs up and down while sprinting. Perhaps if the goal was to get a large weight over my head for a quick delivery(like passing an ammo box overhead to the guy in the chopper whos taking off), this would have higher transference:

Yeah, the jerk was a bit sloppy, but jeez the mans jerking a buck 87 kg...so ill overlook anything.
He starts with a good power angle in his hips, strong pull and then DROPS under the bar(as it should be), using his LEGS. So in the full clean motion, his legs go
extension, contraction, extension. Just like a run. His knees open up a bit...but for the goal of lifting heavy weight, makes sense to open up his hips to get more stability. I made a note to try to keep my knees and legs more in...streamlining like in a run.
So without further ado, here are some of my trials.
Total weight:105lb.(75%bw)
(Reps):all in all, i did about 50 total in a period of time...it was more about the form today.
Considerable focus on form and dropping beneath the bar...subsequently using my
LEGShttp://www.youtube.com/watch?v=NzOhwp6Eb-c
Notes:
*I have to reduce the angle in my legs a little...45 degree optimization for MAXIMAL POWER(and to use my glute more).
*Have to extend more explosively(perhaps lower the weight?). It looks like im dropping prematurely/not reaching full extension
*I think im sitting too far back...it looks more like a sumo squat. I thought I did a good job of preventing my feet and knees from traveling sideways...but I guess keeping them in more will help with this. Also, making sure I keep an erect back on the catch will help this too. Ie. my finishing knee angle is much smaller than my start angle...meaning I have trouble generating power after the catch.
*With some more practice to get comfortable, perhaps I should try so stand up quickly as well after catching the bar and completing the squat...to complete the extension/contraction/extension model I was seeking.
I guess ill keep working with these.
Gymnastics
I went to open gym at our local YMCA, where I spent some time working on glide kips(like those used by gymnasts). I notice a fundamental difference between these kips and muscle ups done elsewhere.
The main difference seems to be in line of pull. A muscle up like this(

By using the muscles(hence the 'muscle up'), you can bend (or not if you have the shoulder strength)at the elbows to reach the top.
What I was trying to do is a kip where the arc was the goal. By kicking out my feet at the apex of the swing, and levering my arms, I can kip using a swing
Here is a video of one of my kip to kip followed by the backtuck game we played at the end(which i lost):

Rock Climbing/BuilderingI finished out the day by hitting the ol' rock gym to work on my finger strength and kinestetic awareness. Here is a picture from the madness!
We worked on a bunch of buildering routes, as well as a game where we climb around the center wall, following the last persons holds, and not making any noises when we contact the wall.

That pretty much sums up Friday's day of adventure.
