I have a mountain bike on a resistance roller that I use to workout, and I also use a heart rate monitor to keep my heart rate at 145. If I workout in a cycling position with my hands on the handlebars, it takes much more effort to maintain 145 than if I sit upright with my hands by my side.
Why is this, and does this mean my upright workout is less effective than my bent over one, even though I'm maintaining the same heart rate?
