As I said at the end, "In both cases, the person will improve more quickly if s/he uses a serious training regimen, but it all starts with and comes back to putting rounds downrange or miles on the tires."

I could be wrong, but I believe most people don't have the discipline to do something they hate if there is not incentive. For folks who Enjoy doing a thing, that's the incentive. People who want to buy success don't generally want to do the practice because it seems like work. People who enjoy the activity can keep it up because they like doing it.

In the case of just riding more or just shooting more not bringing the level of improvement one seeks ... Google that thing.

But really, for cycling, riding more is the best way to develop---Depending On Your Goals. Do you want to ride trials? Tricks? Offroad? Serious competition? For each specialty you will need to learn training and riding techniques, so I cannot give you meaningful general tips. That's where Google can help.

For me, being a better cyclist involves mostly strength and endurance. I have already mastered basic survival skills such as working with automobile traffic. I need to improve my balance and bike handling, but mostly that can be achieved through more riding---when I feel completely at home on the bike again, I can work on hopping obstacles and such.

Mostly I need more miles and more effort. I'd say, figure out what you want or need and folks here who are much smarter and more experienced than I can help you ... or Google it.
