You're giving your energy body a continual boosted supply of energy by filling the sub-navel - I'd just trust it to know where the energy should go.
If you're in training for some track & field sport and you eat your Wheaties you don't have to inject them directly into your feet
! As you use your legs, your body'll route the energy where it's needed. Of course if you're on the edge of malnutrition then it may take a while before the extra energy reaches your legs, but when things get balanced from the steady supply of energy (er, Wheaties in our metaphor) then the surplus will find its way there when it's healthy for it to do so.
Mmmm, Wheaties...!
