I have been walking outside every day, anywhere from 30" to 75" - not super fast walking, but I do go up and down a few hills, so work up a sweat. IS that considered chronic cardio because I do it every day? I thought walking daily was a good thing as part of Paleo - so I am confused!? I also do yoga and was doing kettlebells for awhile, but have had issues with my back/neck area, so not doing any heavy lifting right now. Thanks!
