. . . is a great way to keep exercise playful. Or, to avoid exercising at all.
It is also a great way to avoid the discomfort, uncertainty, novelty and, potentially, necessity of exercise in other settings.
A gym, exercise studio or the office of a smart paramedical professional might be where the substance of your next exercise progression might be found.
I am assuming, however, that you want to progress. Or, at least, not regress.
Playing around outside, even hard, is necessary and fun. It will only get you so far, though, when it comes to your health, and may even send you back if you have encountered a specific health problem.
You might still want to hang on to it, but preference is mostly irrelevant at that point.
