Chicken or the Egg?
When walking in the halls- tighten your muscles- carry a back pack? keep from your torso up- in sanchin- will save back and sholder- switch your pack from side to side often. So you don't damage your sholder with how heavy books are-
We try to teach and learn good posture while practicing Sanchin in order to do it properly, now
you've flipped the table and teach us to practice Sanchin in order to assume good posture outside class.
Yes! I guess whatever goes around comes around.
Your holding the books, K, shook up a little more rust at the edges of this aging cranium.
In the first four years of the 1960s when I wasn't socializing or doing homework I played the guitar -- a lot, and used hand-held finger grippers to strengthen my fingers and forearms, but it wasn't until about thirty years ago, yes, from about 1973 through 1977 I did finger exercises while driving back and forth to work on this state's longest parking lot during crash hour, a painful no-brainer [both the drive and the workout!].
I carried with me two of the hand-held finger grippers, one medium strength and one tough to squeeze for any larger number of reps; the ones that are open and wider at one end and have a hard spring-steel loop at the other end which provides the resistance to the muscles when the exerciser is squeezed. They can be had today and seem to have been around since the beginning of time.
Only I used them in a non-conventional manner.
Rather than grabbing and squeezing them with a full grip as was advertised, I instead used my fingertips to squeeze the handles together. The little pinky gets too much of a workout, so I reversed the hold on them. The normal way was to grab them with the pinky holding on to the widest end, which I did, but was able to maximize the utility of those exercisers by placing the thumb and forefinger at the wide, or open end, thereby the pinky was situated at the narrower end, thus allowing a tremendous opportunity to strengthen that little guy as well.
My drive was about 45 minutes or more each way, and I often used about 30 minutes-worth in the morning on the way in during the boring drive.
I remember building up to doing a number of sets of 100 reps on the lighter ones and a number of sets of 30 reps on the difficult ones. Often there was 5 minutes or so recovery between sets because they do burn.
I hope that gives you a few more ideas. BTW, I carry [carries] books around at work all the time and sometimes hold them as you advertised although I'm not into peaking body strength anymore; I've already done my damage in my youth, and it's up to you younger Lasses and Lads to take up the slack.
Early this afternoon, GEM and I were talking about aging a little and neither of us feel the weight of our years as many of our constituents do and both agreed it was Martial arts, er uh Uechi-ryu, practice responsible for lessening the weight of the expanding pyramid of increasing numbers resting upon our shoulders pushing us down toward the dust from whence we came.
Always with an even keel.
