There's a pretext for this question which is a spoiler:
It is only revealed very late in the movie that the Taskmaster is actually Antonia Dreykov, a woman.
in order for this reveal to work, the filmmakers chose to obscure her gender in order to take advantage of our natural assumption that the Taskmaster is a man (both due to biases and the character's history in the comics). The armor/outfit is designed in a very gender-neutral way that obscures her form and avoids any obvious cue that Taskmaster is a woman, and likely is in fact designed it a way to make the character appear male (at least to any extent that superhero costumes lacking any obvious cues are perceived as male).
Conveniently, the Taskmaster always wears the outfit/armor and doesn't speak, so this goal is more easily achieved.
In addition, the Taskmaster adopts a wide variety of fighting styles, so again, any stereotypically masculine or feminine fighting styles are irrelevant.
So, the bottom line is, given the need for the character to appear male until the reveal, was the character stunted by predominantly male stunt actors?
Which stunt actor(s) played Taskmaster? Was it different actors for different fighting styles?
