I’ve been following this athlete for a while and she has said she’s been training for years and competed naturally in her last show. Don’t know if she’s still natural now. It honestly looks like she may have lost quite a bit of muscle after her competition on the left, then regained it over the next 6 months while gaining around 4kg and stay pretty tight.
For people who have trained for years, does this seem realistically achievable without any PEDs in that timeframe?
