Abs aren't just there for six-packs; they make you a better cyclist too...

We've been banging on for weeks now about how yoga can help your core, those deep structural muscles that hold it all together when you're on (or off) the bike. The abs are the muscle group you'll most likely think of when you're trying to improve your core, but we'd urge you to look after them in tandem with the other muscles in your trunk, or you'll end up with an inbalance.

With that warning out of the way, on to the exercises.

Road.cc's resident yoga expert Karen Burt demonstrates the 'boat pose' - an exercise that can be adapted for all abilities, and poor inflexible Tony only gets to stage 1.

But the beauty of yoga is the speed at which you'll find yourself improving, and you can take it further as you feel ready and your core muscles strengthen. Karen goes on to show the further stages, which you can move onto.

You'll find you shake when you do the exercises, and that'll show you where the weakness is in your core, and you can work on that by moving in and out of the posture.

Once you've mastered this exercise, try building it in with the other road.cc Yoga for Cyclists videos to build your own personalised yoga regime to keep you fit and flexible through the new season.

After an unpromising start, having to be bribed by her parents to learn to ride without stabilisers, Sarah became rather keener on cycling in her university years, and was eventually persuaded to upgrade to proper road cycling by the prospect of a shiny red Italian bike, which she promptly destroyed by trapping a pair of knickers in the rear derailleur. Sarah writes about about cycling every weekend on road.cc.
