I went to swimming club until age 13 to help with my athsma. I then did nothing beyond a bit of football (soccer) until University.
At University I started rowing, then doing triathlons and cycling from 1998 until 2008. The last thing I did (cycling 120 miles / day for 7 days) caused a lot of damage to my knees (which were already too painful to use rowing machines). Also I've had a flair up of eczema since then that causes my skin to get very red and itchy (that drives me insane, and ruins any concentration for trying to work) if I sweat at all.
I've since had a daughter who's now 3 and I'm responsible for picking her up and dropping off to school (school starts at age 3 in Belgium) which is a half hour drive away. So I have 9 - 12 to work on Mon / Wed and 9 - 3 to work on Tue, Thu and Fri. Plus I'm perpetually disorganised and stuggle to use what little time I have effectively.
The only things I do now:
- Yoga (about 2 minutes to do the sun salutation twice) x 2 per day. This keeps most back problems at bay
- Occasional 20 minute walks
- Occasional cycling (once per month)
Two things got me training when I was healthy:
1. signing up for things - I'd sign up for the London Triathlon which you typically do 9 months in advance. Then the panic monster kicks in at some point to get you to train.
2. Join a club. All the sport I was inspired to do was either at a rowing club or training with much better triathlon / iron man nutters (in a good way) from work.
