I train hard Monday to Friday. I'll do weights and cardio in the gym most mornings and do a spinning class, too.
I lift weights. I'll do a lot of running, a lot of cardio and strengthening. I use my body weight, a TRX sometimes. A lot of it is endurance.
I work out a lot, but it changes day to day. I always start out with some cardio - either a jog, a bike ride, or footwork drills designed specifically for tennis movement. Then I do weights, but I switch the days: one day it's upper body, the next day it's lower body. Then I do stomach and back pretty much every day.
I think yoga has given me better posture. People don't realise how strong it makes you. You have to use your body weight to hold yourself. As you get older, you're supposed to lift weights, but I find that kind of boring. Yoga is lifting my own body.
The same way you train yourself to be physically gifted player - whether you do weights, or running to get in shape or swimming - the mental side is the same way. You've got to train yourself to be ready for whatever.
I do some 400 m. repetition running for endurance on the court. I'll be in the gym lifting weights, or I'll be putting in a lot of core stability to work to improve my balance.
The acting part is easy; it's the preparing - lifting weights and getting your body in tip-top shape - that's the hard part.
I get up at 4:30 A.M. pretty much every morning during the week. I work out for an hour and a half. I do weights and I ride the bike, I run or I play tennis. It's my release.
