I'm posting this because I specialize in Computer & Electrical Engineering
and It's come to my attention that some believe that a taser's effects can be overpowered because one is "strong".
That is frankly, false. Electrical current travels through the human muscular
and nervous system meaning the more muscle, the more painful the blow.
Irrelevant note but: if you're ever shot by anything remotely electrical,
hold your arms towards the ground and not out, if held perpendicular to your body,
the current will flow through to your heart which depending on voltage can be extremely lethal.

But returning to my point, please watch this 2 minute video.
It shows how a guy (who's clearly extremely muscular) is effected by a taser.
