text: NEW & NOTEWORTHY Lower-body muscle size of an extraordinarily strong individual, a World’s Strongest Man and deadlift 
  champion (WSM), was approximately twice that of controls but was underpinned by pronounced anatomical variability in the 
  extent of muscular development ( þ 23–202%): the plantar ﬂexor group and guy rope muscles demonstrating the largest differen- 
  ces. The WSM’s quadriceps size (more than or equal to twice that of controls) contrasted with modest differences in patella ten- 
  don moment arm ( þ 18%) and was uncoupled from patellar tendon size ( þ 30%).
