I do yoga, it’s great – excellent for flexibility and core strength/ stability. Complements cycling – and of course other sports, really well. There are lots of different types of yoga – I do ashtanga/ power stretch which is more dynamic cause that suits me.
Will it help – depends, too many variables to call, but potentially yes.
Find a good teacher by recommendation and go to a class, consistently so you understand what to do and why. It’s amazing how different things feel when someone ‘adjusts’ you into position. Once you get the hang of it, self practice then makes more sense.
Give it a go, if you don’t like it nothing lost. HTHs 🙂
