    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?

    trainers that attach to the back of the bike aren't designed for out of saddle use. having the bike in a fixed position like that puts great stress on it as well when jumping out of the saddle. i assume because you cannot move the bike from left to right is why your spinning doesn't feel right.

    If so, then why do all the riders participating in the SpinerVals video have the same type of trainer? Do you think that rollers would be better? The work out is intense so I felt that rollers would be too dangerous. I do own rollers.

    Not certain about the limitations of the mag trainer, but I do suggest you check that the resistance wheel is tight enough against your rear tire that it's not slipping.

    I have expereince the same problem with my CyclOps mag trainer. I just decided that if I want to work hills I'll just have to tough out the cold outside. If someone knows of another way I am more than happy to try the suggestion.
    There can be only one.

    I've got a computrainer and I've been doing the spinervals too. It's rock solid and you can maintain a smooth cadence, but there is an awkwardness to it, not to mention my thighs burn like hell. I've got to shift my weight and lean forward quite a bit.

    I'm not sure if this is related to what you may be experiencing, but magnetic trainers have a much different power curve than wind or fluid trainers. Magnetic trainers have a more linear power curve while fluid trainers have a logarithmic power curve. The mag trainers also tend to max out easier at higher power levels, which may explain why your spin doesn't feel quite right.

    My experience with a roller set with resistance is that it is tricky to go hard out of the saddle. It feels somewhat realistic and doesn't damage your bike as long as you stay on. I know some riders have absolutely fabulous balance and can do anything they want, but that's not me. However, nothing has the same feel as being outside because you don't have the momentum of the bike. For instance, I do spin classes where we spend about half our time out of the saddle. As far as I can tell, this has very little effect on my ability to stand for long periods on climbs. It uses different muscles and the pedal stroke is completely different. What does have a direct effect is standing for long periods on climbs.
