I have done 2 x 5 minutes on the gym bike so far today and will do another 5 or 10 minutes while tonight's meal is cooking. I am already upping the resistance on the bike but won't push that too far because I am not getting properly warmed up in such short exertions.
I found a quiet 1.1 km local road loop with about 10 m of climbing on it. 15 laps of that would be 16.5 km with 150 m of climbing or about 10 miles and 500 ft. When I get back on the road bike, I'll do that few times to get used to riding outdoors again, before going out and tackling my hilly 19 mile Cragg Vale loop - the one that almost killed me back in July!
I know this sounds stupid but I have been walking up the Buttress path for nearly 30 years and had never discovered a little snicket off it. Okay, I knew it was there, but I didn't know where it went to. Well now I do! Normally, when I walk to the Co-op, I take a flat route, part of which goes along the busy A646. I discovered today that the snicket brings me out onto some quiet back streets which eventually emerge opposite the Co-op. It is a nicer route to the shop, but more importantly, it gives me an excuse to head up this ...
I could go all the way up the path, then turn left down the Heptonstall Road, then left again for the Co-op. The thing is - that turns a quick trip to the shops into a significant trek, and I know that I won't do it very often. The snicket that I mentioned goes off to the left up by the lamppost at the top of the photo. It only adds a couple of minutes to my walk to the shops, but that 30+% ramp really gets the old cardiovascular system ticking over nicely!
Final message for today - I just spotted
DVT Exercise Guide - Prevention of DVT, Exercises to Help Prevent Deep Vein Thrombosis & Blood Clots,
currently available free for the Kindle and Kindle reader apps.
The small eBook gives a brief description of the dangers of DVT and then describes an exercise programme designed to protect long distance travellers against DVT formation.
TBH - I can't see many people doing all of those exercises on a crowded plane, train or coach but you could do a selection of them. You could also do some of the exercises during your office tea and lunch breaks, or while working at your computer. Many sedentary office workers are developing DVTs these days.
PS I would be extremely wary of some of the head/neck exercises! It would easy to do some damage to your neck so I think it might be better to limit yourself to slow, gentle left-right/front-back tilts and avoid the rotational exercises.
YAY COLIN !
