Yoga can help runners with both strenght and flexibility in crucial areas.
Why should runners do yoga?
Primarily to lengthen tight muscles but also to strengthen the core, feet and ankles; improve running posture; breathe better and even train the mind.
What kind of yoga?
If you are running long or hard three or four times a week I would choose a gentler style such as Hatha (static, long-held poses) as it will allow much-needed time for muscular release and valuable physical and mental downtime. If you are running less or don’t have a race scheduled and need to build strength, a stronger class, such as Ashtanga or Vinyasa, will do this.
Here I leave the link to two yoga routines you can practice at home:
