Hi Jo,
I liked reading your articles. They are informative, well written and it's obvious you spent quite some time writing those.
I understand the idea of your latest article is to encourage people to get into the sport (and it does that quite well), I just think the whole fitness aspect and the ease of getting into kiting is taken slightly out of proportions.
More than ever before, kiting attracts an older and less active population. I've heard quite often students tell me they want to get into kiting to get fit while they actually haven't been active for a very long time. Needless to say those are the students who often lack the most coordination and have a hard time going through a 2h lesson without getting exhausted, this means they progress far slower than most others. Many of those say they can swim 200 meters (medical questionnaire) but won't have enough fitness to swim after their lost board after a self-rescue for example.
The way I look at it is it should be the other way around, newbies should ensure they have a minimum fitness level to get into kiting, so they can actually enjoy the lessons and not physically struggle to learn. It's also a matter of safety, having enough fitness to get yourself out of trouble... and that 77 YO guy who has his safety leash attached to one the back lines

...I wouldn't want to see him release his safety in strong wind with no one around to help...

Of course you don't need to be athletic to get into kiting, but having a minimum amount of strength-endurance in your legs, back and core is important along with swimming endurance. Doing a few weeks/months of cross-fit classes would be great way to prepare the body to learn kiting.
It's during and after the first few lessons that students will spend the most energy (walking upwind, body dragging, board recovery), but once you're up on the board mowing the lawn won't do much good to your fitness level. The majority of kiters are just cruising around, which uses a low amount of energy and once your technique is right, not much muscle effort either. This means for the majority of kiters, the health and fitness benefits of 1h of kiting are far from those of a 1h workout at the gym.
Of course it's better to go out kiting than sitting at home watching TV, but to have
real effects on your fitness with kiting you'd have to go out for multiple hours at a time, more than 4 times a week AND do more intense riding (waves, racing, freestyle, etc.) and not just mowing the lawn.
Many students are disappointed by the amount of effort, time and skills required to learn to kite after being told things like '' learning to kite is VERY easy'' or ''you'll be cruising around in a few hours''... Of course it's a nice sales pitch and a great motivator to get in the sport, but it can have an adverse effect setting unrealistic expectations.
People who are learning to kite ''very easily'' represent about 20% of students and are almost always the ones with the most active lifestyle and/or a heavy sports background.
Of those 80% left, I'd say about 60% (your ''average'' learner) will find learning challenging, not so easy but definitely within reach and can become independent and competent kiters within a month or so, assuming they took multiple lessons and got out multiple times a week after that. This could take the entire season if students can go out say once a week on average.
The 20% left is those for who learning is much harder. The progression is slow paced and kite control is difficult even after 4-5 hours of flying. Often, a lack of fitness and/or a poor sports background (i.e. no board sports) slows the progression down even more. Those students need to be highly motivated and have an above average level of perseverance. Some of them will make it, but it typically takes many months even with regular practice and double/triple the amount of lessons usually recommended.
I know it's not the best sales pitch, but it's the reality I've noticed after teaching close to 700 students.
In my experience, being able to dedicate enough
time to learn, progress and practice is the biggest obstacle for students. Let's face it, it's a very time consuming sport, especially when learning. You can get a gym session done in 45 minutes, same for practicing a lot of sports as well, but to learn to kite you need to allocate
multiple hours per session and go out multiple times a week otherwise you probably won't get the results, which won't motivate you to continue. Not many people can dedicate that much time and have a flexible enough schedule to get out on the windy days.
The second biggest obstacle would be
money. Students often don't realize they will eventually have to fork out up to a few thousands just to get a basic kit and multiple lessons, only then to realize they need to spend more to go out in all conditions...
The third biggest obstacle I think would be
perseverance and unrealistic expecations. In my experience, people who tend to give things up easily and are just ''curious'' and ''want to give it a try'' thinking they will be on the board within very little time and effort are very unlikely to become kiteboarders.
that's the way I see it anyways... Assuming someone lives somewhere windy with the right locations. If someone ticks all those boxes the rest will come
naturally and the chances of becoming a kiter are very high.
