I’ve seen these sisters since they were seven.
IMO from my 40 years of tennis I conclude there are lots of steroids being used in tennis these days.
The William sisters are IMO steroid enhanced. The muscle development is IMO UNUSUAL. They also both displayed the intermittent play in their career due to injuries that you would expect from steroid use. I believe that Martina was also very steroid enhanced, she was the mother of it in women’s tennis IMO.
Same for many on the men’s side. Probably Rafael Nadal based on his body and injuries.
RE: The William sisters are IMO steroid enhanced.
Why aren’t they being tested like they do the cyclists or baseball players?
