group of people participating in a workout challenge in a large indoor space, likely a convention center or similar event venue. The main focus is on several individuals who are performing lunges while carrying heavy, cylindrical sandbags across their shoulders. These participants are dressed in athletic wear, and some are shirtless. They are moving along a marked track on a dark gray or black surface. Spectators can be seen in the background, along with branding and advertising for companies like "Les Mills" and "Microbiotfit". The ceiling of the venue features bright fluorescent lighting, which illuminates the scene. Overall, the video captures the intensity and physicality of the workout competition.
