Using both fists (or, figuratively, hands).

[Tim] Henman's view is that [Andy] Murray must aim to have [Rafael] Nadal hitting two-fisted backhands on the run.

Soon, Travaglini was caught two-fisted, with a Kane's bacon-crumble in one hand and a maple-bacon doughnut from Union Square in the other.
