Roger Federer says he is still fresh and energized for the indoor events, and does not see it becoming common for players to take off the second half of the season.
The 19-time Grand Slam champion is playing this week at his local event in Basel, having won the title at Shanghai a little more than a week ago. But a limited schedule means he is still physically and mentally sharp.
"I was surprised I was not tired," he told *Tages Anzeiger*. "I took three days off, I've been training again since Thursday, doing gym and on court. I feel good.
"I still have energy for the rest of the season. The break during the claycourt season had positive consequences, the [hardcourt season] I just played Montreal and the US Open. It was tough I had to invest so much in the back—massage, stretching, everything. This also requires energy."
