Just bought a bike trainer (it stops the bike moving and applies friction to the rear wheel) and I'm doing 2 x 15 minute sessions per day. I'm about to get a rower so I plan to do the same amount on that, hence 1hr per day total. With just 15 minutes per day though (my easy-to-do starting point) it's made a tremendous difference to how I feel. Not sure I'm working any harder though *8) I just feel better.
