Well, to be factual, TUT has been around before Gironda. The theory, or exercise science, probably in the late 1890's.. And is one of the keystones of function and establishing muscular growth.
It's also not about the weight on the bar, but how it is handled. The whole point is to target the roughly 2/3's phase of any exercise. There are three phases to a muscle contraction;beginning. middle and finish. Not about strength, so much as it's about keeping consent tension on the working muscle.With a full ROM, there is encountered portions where the tension on the muscle worked, is greatly reduced. Losing the whole point of complete tension throughout the exercise.
Thinking I explained all that in my previous posts, guess I didn't do that well of a job. It's not the only way to train, of course, just a different approach to potential increasing muscle mass. And in a shorter period of time. Full ROM's and partial reps are another. I prefer partial rep training (heavy rack protocol), but that's just me. Help yourself to any training method you wish. No one will every agree one size fits all.
Wooo: not a question of focus of the mind or control, but only watching the breath. You don't have to understand anything. Pretty simple, really. Getting the breath to around 4 or 5 breaths a minute and the heart beat to around the 4 or 5 beats a minute level only takes patience and time. There is the point of reaching a very deep state of awareness. Usually 20-30 minutes in the morning and night of this basic and simple meditation. Then when you have reached and entered that very quite state, just listen for the sound, light show or whatever may appear. Can also do special breathing exercises and spinal locks, advancing even more. Remembering also, that Yoga is not a religion, as some may think. Just another way to approach life.
As with D.O.U.P.experience; look at gymnast to see the value of full stretches. I had suggest extra,extra wide to very close grips from a chinning bar before, with hanging in a loose style. Even adding weight around the waist, as you progress, which in some cases, can be good for spinal adjustments. Hanging from one arm can also have good benefits.If you find that you need straps to help the grip, than use them. Good Luck.
