For a few seasons I did yoga and running in the winter to stay in somewhat decent shape while in the off season. However, last and this year I've incorporated lifting and base mileage and feel better. I do bodyweightfitness regular routine from r/bodyweightfitness and ride 10hrs a week. It consists of stretching which I enjoy and I've read a few studies that lifting also helps with flexibility, so I believe I am not missing out on much. Plus my lady is liking the size I am getting on my arms so that's cool. Some days I do miss yoga and may use my off day to incorporate once a week. Cheers
