Obviously we want as much power to the pedals as possible and there is a lot we can do.
Typically we will find between 20 and 50 watts from corrrecting the position in a bikefit.
From there on, the rider typically will need to invest in strength and flexibility around the pelvis. The pelvis being the bottle neck of resistance in the biking, thus the area to focus on improving the postural fitnes.
There is a lot more we can do like stabilizing the feet, optimizing the time to result ratio of the training by developing a good training plan and follow up on it. All with the focus to increase the amount of power we can put to the pedals.
