What has been the key person for Roger Federer's longevity? The Swiss player indicated that his lifetime fitness trainer Pierre Paganini helped him a lot to be successful in the late stage of his career. 'He doesn't show up much at tournaments, only from time to time', Federer said.
'So the hard work gets done away from the tennis tournaments really. There's only so much you can do during. There's a lot of maintenance going on. We've worked together for a long time. We really got to know each other from 14 to 16, then not 16 to 19 because he left the Federation.
Then I started with him again I think at 19 or 20 years old until now. He's been a great man in my corner. Yeah, I mean, clearly we've worked unbelievably hard and I think in the right way, as well, to keep me injury-free.
The great thing with him is we have always very open talks about anything. Especially with him and Severin and my wife. Basically we can talk about a one-year schedule within about 20 minutes so we can all get it done very quickly because we know each other so well.
We know what we want to achieve. We know how much I need to train to achieve certain things. I think last year was particularly challenging for both of us with the back problems I had. Where do we go now? Are we allowed? What can we do? I think we were all training with the hand brake on and it wasn't very enjoyable.
He would always ask me, How does this feel? Is this dangerous for you? We just felt this was not the way to go, so we had to figure things out. I'm happy we did so.' ALSO READ: 'Serena Williams' extravagant outfits won't be accepted at French Open
