Interesting...I can stand and pedal on the trainer MUCH better than on the road! I think on the road I often end up in too easy a gear since I am a spinner and thus may not upshift enough before standing. I actually enjoy standing on the trainer, but on the road, since I am climbing a hill when I do it, it tires me quickly, and I have a hard time getting my weight centered in the right place (tend to be too far over the handlebars) so my effort is not all that effective.
When I fractured my pelvis and started back on the trainer eight weeks after surgery, I was not allowed to stand on the bike (no weight bearing). When I was allowed to do that at about 12 weeks, I tried, but could not coordinate the effort at all so had to sit back down immediately. The leg on the bad side just couldn't make circles/pull up (my hip flexor on that side were severely affected and required lots of PT). As I healed even more, got stronger and did more PT, it became easier and easier. But since you're strong enough to stand on the road, it obviously isn't that with you. Hmmm.... I'm perplexed! It doesn't seem like it would have anything to do with your weight. There are some pretty big folks on the "Team Clydesdale" Spinervals that stand and pedal. I wonder if it's bike geometry?
I am usually in the large chain ring (50t) and one of the smaller cogs in back when I stand. I keep the trainer on the "2" resistance setting (out of 5, where 5 is the most difficult), if that helps at all. All trainers are different, tho....
Good luck, CA -- let us know if it gets any easier!
