单集简介 ...

Gavin MacMillan spent years building athletes nobody expected to make it — boxers, hockey players, tennis pros. Then Aryna Sabalenka hired him, and the tennis world started paying attention. In this episode, Gavin breaks down the serve transformation that took Sabalenka from 6 double faults in a single final to 6 double faults across an entire tournament. He explains why 99% of strength coaches in tennis are operating on the wrong principles — and why bigger, faster, stronger is the biggest lie in the sport. He's now working with Coco Gauff.

  • Tennis, it's the single hardest sport in the world to succeed in professionally.

  • You have to be a great athlete, so you have to have great speed,

  • you have to have great endurance, you have to have the mind of a world-class chess player.

  • Like, there's just nothing it doesn't ask.

  • There aren't world-class players that aren't smart out there.

  • It doesn't exist.

  • If you look at the first final arena play, I think she fell to six times against Robaka.

  • But if she flash forward the next year, she double-faulted six times the whole tournament.

  • With Arena, if she was serving at 70% first serve, she was unbeatable.

  • This idea of bigger, faster, stronger is just the biggest lie ever told.

  • Everybody played.

  • So hockey was a travel team.
