After my friend (who also teaches yoga) asked me to stand on one leg, dip, then the other leg, she told me that I need to strengthen my glutes. In other words I have weak bottom muscles, well really! She also said that's why I pulled my thigh/quad in the first place and not to go back till it feels pain free.My left leg is weaker than my right and gave me strengthening exercises to do. Well that's a bummer then, tee hee!
There's definitely more to this running business than I thought, hmm oh well onwards and upwards!!
