Being a weightlifter, Sonny Websters ban was an interesting one. He was a decent lifter, went to the Rio Olympics but was never a threat to medal there or in a European competition.
He tested positive for Ostarine in May 2017, was offered a 2 year ban if he admitted taking a substance but spent his life savings fighting the charge. End up receiving a 4 year ban which should have expired 2 days ago (now aged 27), however he refused to stop coaching athletes (banned athletes aren't allowed to associated with federation member athletes, so no training them, or even being in the same gym as them). This resulted in a further 3 years being added to his sentence and he'll be nearly 31 by the time he could compete again, the age most elite lifters looking towards retiring.
In the end he ran off to Australia (he has New Zealand citizenship through family) and coaching Crossfitters in person and online.
