The video features a group of people climbing on rock walls inside a gym. The climbers are wearing safety harnesses and are attached to the wall with ropes. The gym has several climbing walls with different levels of difficulty. The climbers are seen using their hands and feet to navigate the walls, with some climbers reaching the top while others are still making their way up. The gym is well-lit and has a spacious layout, allowing for multiple climbers to be on the walls simultaneously. The climbers are wearing athletic clothing and appear to be enjoying the activity.
