The acrobatics start around the 2:30 mark. They do some bridging acrobatics. This is different from the gymnastic or wrestler bridging exercises, but instead involve some tumbling, hanging, and handstands on a bridge.
This is followed up by some interested tree climbing. Instead of going up the base they start at a branch and move across to another one.
At 5:30 they say they’re starting with some parkour. What it really is is jumping off a tall building into some crash pads. Although this move wouldn’t take much skill I’d still say many people would be afraid of doing it.
