I have done yoga for old sport injuries and I have been surprised by how much it helped. I didn’t have any formal training. I just followed along to Youtube videos.
I have also been very interested in learning more about yoga and applying it to my work with athletes. I have used mindfulness with athletes and they have found that to be very helpful. I would recommend the book The Psychology of Enhancing Human Performance: The Mindfulness Acceptance-Commitment (MAC) Approach by Gardner and Moore. I would also recommend using the free guided meditations from the UCLA MARC website. I have encouraged athletes to access the guided meditations on their smart phones and do 3 minute meditations when they have time throughout their day.
Ana Del, thank you for your recommendations of yoga breathing techniques. I will have to look those up on Youtube when I get a chance!
