I did yoga up to week 2 of my radiation.., and now I do a varied version of it- meditative yoga - that way I'm not burning calories but receiving the same benefits of the meditation, I love yoga and cannot wait to get back to it. 4 more days of treatment to go. Yoga is awesome because it works on strengthening and breathing - ts he's you focus and give you a little me time. I am also an avid gym goer but in the interest of saving my calories I have stopped as of 4 weeks ago - waiting to finish this and feel better so I can get back to it. Try yoga - it's not about the end point it's about the journey... Ohm...
