Thirty minutes 3-7 times a day is probably just fine when learning to
ride. (If you need to practice another 30 minutes for good
improvement, then by all means do so.) When you get to the point of
learning to Free Mount and Turn, you may want to spend just 20 minutes
on each. When you get past Idling and Backwards, there will be enough
skills to "perfect" and new skills to learn to fill 1-2 hours with as
little as about 10 min. per skill (Not enough time to get bored
anymore).
Stay on Top,
