yeah, -30 degrees,would be the death of me I think!
Heat soaks into my busted ribs and must admit, does help. Also perfect timing as it will be the end of a particular weight training cycle, so I can rest and recover.
Thanks astonion, I did wrestle with it, saw what you posted obviously, but as this is just a switch off break to get some heat and relaxation, I should be fine. I'm pretty self contained!
