Sarah, 37 years old, personal trainer
I always need to be on the move. I'm always full of energy and it needs an outlet. I just can't get enough exercise! At first I did it when I could, but it became so important in my life that I've made a career out of it.
I always start the day with an hour of exercise at home, I go everywhere on my bike, usually spending between 3 and 4 and a half hours a day cycling around and to my clients' homes. I also exercise with the clients that I coach.
A day without exercise is unimaginable. I get stomach ache, lose my appetite and am less cheerful. A journey by car or train is a nightmare, because I have to be on the move and can't stay still.
Before I started working as a personal trainer, I used to do abs at home, walk to work, count down until lunch time so I could nip to the gym, then walk home at night. I also did an hour on my bike, some weights and aquaerobics to switch off.
It acts like an anti-depressant, only it isn't harmful. I've often gone through periods when I've done over 48 hours of sport per week - it's like a drug. Now I try to do a maximum of 18 or 20 hours. I've learned to manage my need to be on the move. After all, you've got to be careful not to put too much strain on your body.
