The first 3 months activity, September, October and November, were summarised in the post earlier. This is a summary of December, January and February. At the beginning last September I weighed about 17 stone, By the end of the first 3 months I was down to 15 stone 10 lbs. Now, at the end of February, I am down to 14 stone 12 lbs. Weight loss has been quite a bit slower therefore but this period covers Christmas and the New Year. In fact I put on about 3 pounds over December. In addition my riding on the road has reduced quite a bit, perhaps not surprising given it is winter. On the whole I am pleased with my progress and I am on target to get below 14 stone in another 3 months, the end of May, when I will probably take delivery of a new Chris Hoy road bike.

December:
12 x turbo sessions total minutes 380
1 road ride 11 miles
End weight 15 stone 10 lb

January:
14 x turbo sessions total minutes 425
2 road rides total 13 miles
End weight 15 stone 5 lb

February:
11 x turbo sessions total minutes 355
4 road rides total 41 miles
End weight 14 stone 12 lb

Following a rough calculation I did in an earlier post I decided it would be interesting to calculate each month’s weight loss as a percentage due to exercise and to calorie reduced diet. On the basis that 1 lb loss is the equivalent of a 3,500 calorie deficit it is possible to use the calories burnt figure given by a combination of my Polar HR monitor and the Garmin ride calculator to calculate weight loss due to exercise and this as a percentage of the total loss over each month. The figures for the months I have the data for are:

November: Total loss 6 lb, loss due to exercise 2.25 lb or 37% (exercise calories = 7861)

December: Total gain(!) 3 lb, loss due to exercise 1.1 lb, presumably the gain would have been 4.1 lb without the exercise  (exercise calories = 3987)

January: Total loss 5 lb, loss due to exercise 1.48 lb or 30%  (exercise calories = 5185)

February: Total loss 7 lb, loss due to exercise 1.7 lb or 24% (exercise calories 6,079)

December included the festive season of course and equivalent to a 2 week break in exercise. It looks like a pattern is emerging of 7 lb loss per 3 months with about 25%-30% dues to cycling. My weight at the end of February is 14 stone 12 lb so by the end of May I could be down to 13 stone 5 lb. This would amount to a total loss of 4 stone since July last year.
