I took your advice and set up in front of the TV and played Call of Duty 4 on line. I set te trainer up at a resonable tension (for me) and a pace of 70 rpm or so and then rode for 35 minutes untill my butt got sore. Differnt position then riding over the bars. I found my self speeding up and slowing down as the action of the game increased......
Tomorrow I will shoot for 45 min.
Thanks for all the great sugggestions.
