Hbgreek,
Interesting debate. However, you say “You approach PE as if it's a formula”, however, surely PE is related to the body and medical issues, fundamentally it is exactly a science?
Medicine and medical matters are the purest form of science? The body is a scientific machine, and while I agree everyone differs, we are all human and all have the fundamentals in how our body operates.
I’m not talking about what weight is hung, I’m talking about controlling a process to deliver gains in the best form possible. I make this point in relation to lifting weights. For example, I can lift dumbbells at home or I can use cable machines at the gym. Both approaches ultimately will give me an increase in muscle to the same standard, however, the cable approach is probably the better form of lifting and likely to give me better results quicker since I’m able to correctly load and ensure the body part takes the true weight on a consistent basis, rather than risk developing an uncontrolled form through home lifting.
So regardless of the weight, I’m saying hanging can give the same feeling, but is under a greater element of control?
As for saying you are inconsistent, that depends. You have gained, but the issue is not that, because if you had a different approach no one can speculate whether your gains or the speed of gains would be different? And of course, angle of load would entirely depend on your biological factors, LOT, inner shaft, exit point, ligament tightness etc.
I’m not saying there is a one size fits all approach, far from that. I’m saying within hanging for example there is great room to cater for individuality, I.e. Duration, weight, sets, angle of hanging, etc. All of those factors will depend on the details mentioned. However, what you can do with hanging is ensure within your own individual program you are getting a consistency of what you need from the stresses placed.
So while what two people may do in a hanging session could be very different, both are maximising potential gains and the speed and optimisation of those gains within a controlled manner, rather than not controlling such factors.
With manual stretching, how do you ensure a consistency of force applied? Maybe your ligs are still stressed and while you feel the load is the same, it is less? Maybe you workout and your muscle increases meaning force applied is too great and causes injury?
After all, returning to weight lifting, why are weights labelled in kg’s? If the approach was solely to go by feel, weights or even distances as regards running, cycling etc wouldn’t be mentioned would they? People should just go on feel alone?
Yet to exercise to complete failure will delivery injury. Surely a much better control is given by eliminating unknowns and controlling factors and gains, be that muscle or ligament stretching?
So I lift 10 kg’s for 2 weeks. Over that period the muscle/ligament etc adapts, I don’t always exercise to failure, but I know within that period the muscle or whatever has adapted to take the weight, then I move to the next stage. This delivers results ensuring consistency and reducing the risk of training to complete failure.
That is just my thought.
