The 27-year-old "Rowdy Rathore" actress, however, admitted it was an exciting scene.
"Just finished my 1st ever action sequence for #AKIRA! Exciting and exhausting!!! So tired but the adrenaline still pumping, bring it on," tweeted Sonakshi.
The actress earlier said she was undergoing physical training for her role in the AR Murugadoss' film.
"I have been training hard and being innovative. Learning something new for a film is cool and a fun thing and very very exciting. I am just going with the flow. I am enjoying what I am learning and trying to do my best," she said.
"Akira" will be the first time Sonakshi will be seen sharing screen space with her actor-politician father Shatrughan Sinha.
