I just started TR last week and have completed my fifth base-building workout. My most recent workout, Antelope, instructed me to try riding in a more aero position.
I was happy to find out that I was actually able to put out more power in an aero position. However, my genitals got very numb and I had to stand up a few times during each interval. The instructions later had me try to anchor my sit bones, doing so required me to severely curve my back and reduced my power; the numbness did go away slightly.
Here are some details on my aero position:
- Hands are on hoods
- Elbows are at 90º angle and close to my body
- Back is flat from tailbone to top of the neck (I think this helps open my hip angle)
- My sitbones are usually at the widest point of the saddle, but there may not be enough support on the wings.
- May be unrelated, but I noticed when I pedal I have a lot of pressure on the outside of the cleats; I had to actively bring my legs closer together to get the pressure even on the cleats. Is this the q-factor people talk about?
Is there anyway I can have my cake and eat it too, i.e. be aero in a position I like without having to curve my back? Would it make sense to get a saddle with a cut out to deal with the numbness?
