The NFC East side, who have won one of their four games so far this season in the NFL, did not play last weekend.
The quarterback told reporters: "I feel good, great actually, rejuvenated, everybody's got a lot more energy coming off the bye week, just ready to do what we know we have to do. And then as a team, I think we're all just moving on from those first four weeks.
"We got the win going into the bye, which is real beneficial to us, but aside from that we didn't really play like we know we can play. So we just have got to get back to doing us and that's kind of the approach I took as well over the bye, just relax my mind and get back to being myself.
"As far as how everyone has responded, I thought we had a great practice, offense and defense, guys flying around. We had the right energy. I think guys had the right attitude and we just have to go ball."
The Redskins face the Dallas Cowboys on Sunday night.
