The man in the red shorts is raising his right hand up to show a stretching exercise move while the other person is watching him.  He continues to show some more workout exercises by flexing his chest muscles and and pointing to his thigh.  Then the other person in black shorts kneels down on his left knee and holds up a long metal pole with his hands to raise it.  The person in the red short explains what core muscles he is exercising while doing the workout.  Then they both stand up and complete their tutorial on the workout.
