With the speed force seemly being about all forms of speed, not just running really fast, I'm thinking that the strength force would be more then just super-strength, like super stamina, leaping, nigh-invulnerability, since tensile strength is a form of strength, and perhaps willpower. Though she would be vulnerable when she's not tapping into the strength force, like Barry when he's moving like a normal person, because perhaps he is until he taps into the speed force to move really fast, like an on/off switch thing to energize them when needed.
She could perhaps also run/move faster in a lighter gravity kind of way, but not in a accelerated kind like a speedster.
Could a Strength Force user, say, give other people super strength or steal strength from people? Like how Barry can give people speed, take people into Flashtime, or steal people's speed?
Do Kryptonians and Daxamites and so on tap into the Strength Force for their powers?
