kettlebells and Apple Fitness

I do not understand the lack of support for kettle bells in the Apple fitness environment. In the discussions, the suggestion is to use the other function on the watch which allocates effort to that of a brisk walk. This is like asking where do I record my jet flying and being told, under the Bicycle tab.

Why is apple not developing Kettlebell routines?

American Council on Exercise:

"To put into perspective kettlebell training’s potential to increase aerobic capacity, Porcari says, “If I was to put someone on a running program, we would likely see a slightly higher, bigger improvement, but these results showed cardio improvements that would be better than a walking program and more in line with what you’d expect from a regular cycling program. In regards to intensity, it’s kind of a cross between circuit weight training and running.”

Researchers also point to the positive implications of being able to increase core strength by 70 percent, especially for the aging population. “I think that’s huge because the stronger people are through the core, the less low-back pain they are going to have,” Porcari says. Similarly, the gains in dynamic balance have major positive implications. “Older people who are doing some sort of kettlebell-like training are going to be more likely to avoid dangerous falls,” he says. “And on the other end of the spectrum, for athletes, the better your dynamic balance, the better your ability to balance when you’re moving and cutting and doing other athletic movements.”"
