The thread... it's alive!

Get a set of rollers. You can use your bike without worrying about damage (frame stresses) or having to use different skewers. Rollers will also keep your core in better shape (you are using all your cycling muscles, the trainer supports the bike so you get to 'cheat' by flopping over the handlebars).

I got e-motion rollers because they allow me to stand up and sprint and are very easy to use (perfect form not required). Interval training videos are not a problem & build quality is excellent.

I have used Kreitlers and they are very well made. However, they are less forgiving and standing/sprinting is difficult.
