In the video, a man is seen performing a plank side raise exercise. He is wearing a blue tank top and black pants with white lettering. The man is using two dumbbells to perform the exercise. He starts in a plank position with his hands on the floor and his body straight. Then, he raises one dumbbell at a time to the side, keeping his body straight and his core engaged. The man repeats this movement several times, alternating between raising the left and right dumbbell. The background shows a gym with lockers and a clock on the wall.
