I turned my hobby into a job when I began Escorting
For me now it's hardcore fitness all the way. Running, swimming, cycling and the gym any chance I get.
You either love it or hate it I suppose..
As you already do keep fit, why not check out the classes at your local Gym? They do everything from Yoga ( which I hate ) to kick boxing and spinning ( which I love )
They start soon after 9 and run up to lunchtime at most bigger health clubs. If that's too early in the day for you they have early evening sesh's for the 9-5 workers. Everyone is usually abit high on adrenaline, so pretty friendly and sociable and stay behind for coffee and arrange occasional days/ nights' out etc.
By the time I've cycled there, done a workout, a class or 2, swam and steamed/sauna'd, had coffee with the girls etc, the day is almost over and I'm way too knackered to do anything mundane like shopping or housework!
A 4pm siesta works wonders and then it's all systems go for the evenings' activities ahead!
It's a fab life!!
