I now have a set of rollers and a trainer. Bought a Spinerval DVD and it's a pretty good source for a trainer workout. A little more variety would be nice but the DVDs seem expensive given what they are.
It will take a bit to get my balance on the rollers - rode it last night for the first time in doorway. Actually had fun. I can see how it will help with balance and spinning form. Now I'm wondering what I should do with the rollers for a structured training session. Thanks.
