Out-of-the-saddle with a Magnetic Trainer
I have just started indoor training with the SpinerVals--no slackers allowed VHS tape. I am using a Performance magnetic trainer, that can be set to 5 or 6 different levels of resistance. When I'm seated, everything is fine but when I pedal out of the saddle, my spinning cranks don't feel right. They stutter a bit. If I the trainer to the most difficult resistance, the problem is reduced but, of course, my cadence drops dramatically. What is it--my bad form or just an inherent problem with this type of trainer?
