What is Passive Insufficiency?
When a muscle cannot stretch further to allow full joint movement.
In context
Passive Insufficiency is a key concept in biomechanics. When a muscle cannot stretch further to allow full joint movement. Knowing what it means — and how it connects to the rest of your training — turns it from jargon into something you can actually use in the gym.
Nishaana is built around ideas like this: it tracks the numbers behind them automatically, so the theory shows up as real progress in your logbook rather than staying abstract.
