Doing a 4:3 this week (Saturday to Friday) and today is the first fast day. But I'm also going to have a go at the
TPW-diet. The "TPW-diet" involves doing 5:2 in combination with large amounts of moderate to high cardio exercise. I can't go and walk the Trans Penine Way, but did make it to the Gym this morning.
I used four cardio machines and selected the 'calorie' target programs and used each in turn at generally increasing levels. I start out by keeping my pulse below 130 on the exercise bike), then all goes to pot on the stepper and treadmill and it's around 150-160, I ease off in the middle of these two on the cross trainer (142). Because of my age when the pulse is greater than 148 the machines are constantly displaying "Attention - Pulse to high" messages every minute or so. The workaround for this is to close my eyes, ignore them and listen to the gyms soothing background music

(but if I hear Nicki Minaj 'Pound the Alarm' one more time I think I'll go nutz!)

Today it's a 700 cals fast (hey it's Sunday!). So I'm aiming to have an approximately (2500 + 800) - 700 = 2600 calorie deficit. Tomorrow is a feed day, and the next fast day is Tuesday, which I've booked off as AL, and so it will be back to the gym then!
Observations: I mentioned previously that compared to trips to the gym last year (July to Nov), my pulse at the end of the 1 min no pedalling exercise bike was 78. It was the same again today!
5:2/4:3 and 'healing mode': I realise this is all anecdotal, but there were a number of other positive signs today. The last time I was regularly attending the gym was in 2008/2009 because shortly after returning from a walking holiday in the lake district, I did my back in lifting a "hippo bag" of garden rubbish and waste into the "green skip" down the recycling centre. It took months to get over this. Then, to cap it all off, I stumbled and fell down a flight of stairs at work, I didn't fall over completely, but landed very awkwardly on my left ankle, which took my whole weight and gave out. During this period all walking was out and I struggled to get from the car park at work into the office. I gradually added in short walks (initially to the canteen and back), then slowly increased over time.
So I was totally over the moon today, to find that I was walking comfortably at speeds higher than those I regularly used back in 2008/2009 and that there were no twinges, stiffness or tenderness and pain in either my back or ankle (and which I was still getting last year and earlier this year before starting 5:2).
