Mmm, while those may be good ideas, they're definitely not connected to the meaning of the riddle. Good thinking, but I'm afraid you're off the mark. Hopefully a hint will help.
Slow or fast? I can’t decide,
But training will fill me with pride.
Physical strength, defensive skill,
Make fighting weaklings easier still.
I’d be a champ, I’d be a king,
But I’m stuck on a single thing.
I need an aid to see it through,
But with help, I will shatter you!
