Or is that hard on your back?
I find biking more than an hour hard on my back. Leaves me pretty tight and often around 30 min my hands go numb, which I think is because I'm not holding myself up right.
:( Really sorry to hear that. My hands often go numb too, and I have to work to get the blood flowing again. Hope things improve as you do other exercises and training.
Tim, want to try my spare ‘bent temporarily? Very easy on the back.
