Since my initially I've been to massage three times, latest yesterday; hot yoga five times and I've not swam. I was also outside on the bike twice in two days as it got milder. Much better at the latest massage...so from what I can tell, yoga is working, increase in stretching, including attention to posture is also working.
I have never liked the gym or having a structured weight routine at home, and I've went years without doing so, so I will stick with yoga for now and see if it helps.
thanks
