Another Pedaling Workout
Here's one I forgot about for improving your pedaling skills. If you have a favorite drill not listed here please let us all know in a comment.
Mountain biking. This isn’t a drill, but riding a mountain bike off road on hilly courses is good for improving pedaling skills. When you ride a mountain bike up a steep hill on a loosely packed surface such as dirt or gravel you must learn to keep even tension on the chain. If you mash the pedals the back wheel will slip and you won’t make any progress. Learning to keep even tension on the chain is just another way of saying learning to pedal smoothly and efficiently.
