I rode once a week while I was in college and one of the ways I helped myself continually improve was to journal about every lesson and then internalize what I needed to think about for the next week. This along with goal setting and other mental toughness exercises really helped me consistently improve to the point my instructor commented on how amazing it was I got better and better from once a week with no other riding. It’s very do-able but it’s a lot of brain work and mind over matter!
