"Legs feeling like jelly after yesterday's workout! The cure?.... Let's do it again today! Gym time! #ABGymCrew let's go guys... (sic)," the "Dhoom" actor tweeted Thursday.
He also shared a photograph along with a caption that read: "Let's add this today too. Time to sweat!! #NoPainNoGain #ABGymCrew @prashantsixpack (sic)".
If one goes by the photograph, he will try out exercises like crunches, squat jumps, crunches on exercise balls and seconds jump rope.
His father, megastar Amitabh Bachchan too joined him in workout.
"Father and Son at gym for 2 hr work out...! The family that gyms together, builds together - muscles!(sic)," he tweeted.
