Okay, this was originally meant to be funny, but I think it can help type people. (Warning, tard-logic to follow...)
NOTE: all the quantifiers are subjective to the individual "weak" and "strong" is not objective, but one's own assesment of the self.
Intuition, focused on the mind. (Internal/Introverted)

= weak minded
Will accept any garbage given to it, but it is exactly this trait which the other functions can sometimes find something good.

= strong minded
Will resist garbage given to it, and it is exactly this which makes for strong follow through.
Sensing, focused on the body. (External/Extroverted)

= strong in body
Will attack and resist external forces, and focus more on external results then physical settlement.

= weak in body
Will shy away from external forces, and focus more on hedonism then actual results.
Thinking, events. (Internal/Introverted)

= strong memory
Can remember things easily, and learn methods to do things.

= weak memory
Cannot remember things easily, so it needs to simplify things.
Feeling, energy. (External/Extroverted)

= high energy
Higher energy leads to enthusiasm and emotionality.

= low energy
Lower energy leads to actual contemplation of emotionality.
Okay, so taking the PoLR points:
ISxj doesn't want it shown they are weak minded.
ESxj doesn't want it shown they are strong minded.
INxj doesn't want it shown they are strong in body.
ENxj doesn't want it shown they are weak in body.
ExFp doesn't want it shown they have weak memory.
IxFp doesn't want it shown they have strong memory.
ExTp doesn't want it shown they have low energy.
IxTp doesn't want it shown they have high energy.
Alpha/Delta = weak in body and mind
Beta/Gamma = strong in body and mind
Alpha/Beta = high energy / no memory
Gamma/Delta = high memory / no energy
Interesting...
