Words of wisdom to live by:
Really? Drugs and anabolics are SUPPLEMENTARY? You have to work out anyway? Say it ain't so! Sort of like ab sculpting, Zerona, artificial tanning and hair removal might be SUPPLEMENTARY to diet and exercise? I accept your apology.
What surgery? Ab sculpting? Is that done to treat injuries? Are you suggesting that Zerona or cool sculpting should be REPLACING exercise? I disagree. There is no substitute for hard work.
Then perhaps the article on ab sculpting never should have been published on this site? Funny how you don't address that article at all.
I think you should post on the knitting site ... about "fitness." Here is a thread from the knitting site for you to start with, and then knit one, pearl two:
I don't think you are going to be losing any weight by walking and knitting... For fat burn, it's more about time spent maintaining an elevated heart rate than actual distance covered. You need to be walking at a greater intensity than just a stroll, chatting with a friend. You figure your maximum heart rate by taking the number 220 and subtracting your age. For fat burning, the optimum percentage to work at is 65% of your max. Therefore, if you are 50, 220-50=170. For fat burn, 65% of 170=110. You need to be walking with an intensity that brings your heart rate up to 110. This would need to be maintained for at least 30 minutes. (Inexpensive heart rate "watches" can be found at Walmart or elsewhere, to wear and check during exercise.) In order to walk with your heart rate at that level, you need to have your arms involved, pumping your arms. To knit while walking you are holding your arms even more still than you would if you were on a casual stroll, without knitting. It will also mess with your depth perception to be looking at your knitting in your hands, and also where to place your feet on the pavement.
What I'm trying to say is, devote your attention and short amount of time to getting your exercise properly, then come in and rest and do your knitting! Sure you can knit and walk, but it's not much exercise. Better than nothing at all, I suppose, but I wouldn't expect to see much weight loss to speak of.
Ditto with reading a book while on the treadmill... The people I see at the gym who read on the machines are not the ones I see changing body size/shape.
