Cyclist Robert Förstemann's Olympic-sized thighs first came to the public's attention during last summer's London Games when a Twitter picture went viral.
And now the German has stunned everyone again. In preparation for The Revolution Series cycling event in Manchester this week, ITV presenter Sian Welby measured the circumference of one of the German athlete's thighs - which measured 28 inches.
Welby tweeted this photo of the Olympian's thigh:
The track and road cyclist first rose to prominence back in July when his fellow competitor Greg Henderson tweeted a photo of him during the London Olympics.
The image was retweeted and beamed around the world thousands of times.
