Jim:
Hello again from a very wet England. I’ve been reading with interest the articles on physical fitness and would just like to add my two penny-worth.
Cross country skiing is generally considered to be about the best form of aerobic exercise, inasmuch as it works pretty well all the muscles. The Nordic company do a ski machine that retails new around $700.00, but second hand they sell [on eBay)] for peanuts.
Here is an example of one currently on that well known auction site. GBP 15.00 is about $30.00 – a very small price to pay for the ultimate exerciser. Admittedly, they take a little while to get the technique, which is probably why you see so many of them for sale, but they are superb. I would recommend everyone with an interest in post TEOTWAWKI fitness look at them. Oh, and they’re adjustable, so every family member can use them, and at these prices, get a couple, for spares – I’ve got several stowed away ready to export to our new GOOD location and one in use right now.
Keep up the good work. Very best wishes. – Michael
