I find it really hard to take people who go to the gym seriously.
Think about it for a second. You go to the gym to get fit.
Why are you unfit? There's a really good chance you drive around everywhere right? So you pay for a car, petrol, maintenance on the car (tyres, oil etc.) and find you have to pay $30 odd ($1560 a year) a week to keep fit.
What if you were to leave the car in the garage every now and again? Go and walk amongst people. Carry something heavy home. Enjoy the neighbourhood.
If you really must go the gym..... walk to it. It's a warm up in a very real way.
