I've posted up before about the left 'sleepy leg' and had plenty of good feedback. Now in my sophomore year of OC1 paddling, I'm noticing issues with this aging bod. Mainly, I have super tight hamstrings, hip flexors seem 'pinched' (have an XM with a huki seat which is nice), and found tightness in my thoracic area.
I'm working with a trainer regarding body mechanics and working opposite muscle groups, specific rotational stretches.
