On the second Tour event, Are, you'll encounter a giant Thor statue near the end. It's much larger than the Viking statues that hold shields. Make sure you're powered up when approaching it (there are plenty of stars on the way) and jump off the ramp in front of the statue. Quickly strike a T-pose (stick your arms out in a T-shape). You'll soar over it and get the Achievement.
