Sit down or stand up

[Cringles]

I'd defiantly suggest Yoga. The DDP yoga is the one I've settled with, it's helped my back in general, & my dad who has sciatica, has had all symptoms pretty much gone after a few weeks.

Any core exercises will be good. Kettlebells are good, but can make you worse if you don't now what your doing.

Sometimes It's a bad habit to, I found I'd tense up cycling up hill, still catch myself doing it sometimes. Clenching my jaw was a weird one I got rid o :P

I'm 54, and I've had to do stretching exercises since my late forties. Many of the stretching exercises for cycling seem to have their origins in yoga. many books also recommend a walk after a ride, before stretching. Core strength exercise is necessary in the winter especially, as many trainers don't require balancing the bike, with the exception of rollers, which lack resistance. So a little weight lifting or machines are quite helpful to making you a stronger biker when you are on the road .
