hello, i'm a n00b tri guy trying to work on my cycling. the recent inclement weather has forced me into my gym's spinning classes and i found myself concentrating on my upstroke.

question is, do you put as much effort into your upstroke as the downstroke? should they be equal? i understand that this would be the most powerful, but it felt really weird and my legs tired quickly. i was able to increase RPM's at higher resistances (with the goal of trying to keep around 90 RPM's or so).

does this simply mean those muscles are under-developed or should i not be "pulling" that hard on my upstroke? should most of the power come from the downstoke?

hope this makes sense, thanks

The rule of thumb is to "pedal in circles" by applying equal pressure all around. This however does not really make complete sense as you can generate way more power in your downstroke than the upstroke; also no one really does pedal in *perfect* circles. If you look at TT/Tri bike design your hips are in a forward position to place more of your weight over the downstroke and thus be able to apply more power in each stroke and fly down the course...

One legged drills will make better sense of this for you...these allow you to work on identifying your dead spots and work to eliminate them. You will easily feel the difference.

Do a search (training forum & road forum), there has been a lot debated and you will get more helpful info than this.

What i've found is that you don't need to "pull-up" so much that you actually pull the pedals upwards. Rather, concentrate on lifting your foot just enough to unweight the pedal on the upstroke.

+1. That's exactly what I wanted to say, but I couldn't think of how to say it. Thanks Psy.
