I take electrolites, msm, bananas, plenty of water and still my muscles hurt, specially the hamstrings and my lower back. Sometimes my practice is really good and I can do even the head to knee pose with no problem but other times I am not able to do it at all…what I have to do to relax my muscles? I practice 4 or 5 time a week and sometimes just 2 days a week because the pain is annoying..
Do you think that this much time in the heat can weaken my muscles and bones? I have been practicing for 3 years now and do you think that s too much exercise? I would love to hear some answers. Thanks
