A year ago, a one hour rowing session would burn 120 more calories than it did today.



How's the work being calculated?

As you get fitter, you should be able to perform more work per unit of time.

On my fitbit.

I have to pace myself on an hour long session - I want to be able to make it to the end! So it's likely I'm not going as hard as I could, although I'm covering more distance (as calculated by the rowers computer).

The fitbit's using HR & weight presumably?

The "more work" question I suppose comes down the whether the greater distance travelled more than offsets the lower mass being moved (or maybe the distance cal already takes account of mass?). My strong guess is that for a given intensity of perceived effort you'll be doing more work, ie burning more calories, now than when you began and were less fit, and that the fitbit number is misleading. One of the bonuses of getting fitter (become more powerful) is being able to burn more calories in a workout.

This is the standard pattern seen with bike turbo trainers (where the work done can be measured accurately via a power meter rather than relying on a proxy like HR with lookup tables).

If you have access to a time machine then you could do a 1hr test on your mate's C2 (if that's got power measurement?) back when you were unfit and compare to a similar test now!

Yes, using the Fitbits Heartrate monitor. Mt weight is updated regularly manually on the Fitbit. My wife suggested it took less calories to shift 11 stone than it did to shift 15+stone, which I guess sounds reasonable.

Anyway, here's a couple of 'before and after' rowing readouts for you all

Before:
14th of February 2018 (about 6 months after I got the rower and a couple of weeks or so after I got the Fitbit)
Basically, just trying to get to the end of a 30 minute session. 2 x longish breaks where I had to regain consciousness after a cardiac arrest.

Image

After:
6th of August 2019. The first 30 minutes were at around 70-80 watts constant and 26-27 strokes per minute. The rest of the session was made up of short 110 watts+ sessions with a 60 second rest in between.

I've been thinking of ways to keep my weight down and I recall a tv program from a couple of years ago which looked at why some people do no exercise and seem to eat what they want. Like we all used to do when we were teenagers.

They looked at several different people and whilst some did eat what they wanted, they just ate very small amounts of it - which isn't really the way forward for me. A couple of others ate large amounts of high calorie foods in decent quantities, so the study focused on them and what they found was that they regularly (unconsciously) skipped meals - most commonly lunch. One woman ate breakfast with her kids before getting them out the door and then didn't eat again until she sat down to a big dinner with the family.

So whilst it's not fasting in the normal way, it's certainly something to think about. The problem is finding a food to get you from breakfast to dinner without you climbing the walls.

Modern breakfast cereals are usually filled with carbs and sugar which gives you a boost in the morning but which fades away rapidly towards lunchtime.

Eggs are quite good at satiating your hunger, but are a pain to boil up in the morning and have certain other...err.. 'binding' attributes if eaten often enough.

For something to last through to dinnertime, for me at least, it's got to be oats. I've haven't eaten oats since I was a child and that was Ready Brek (not the healthiest version of oats I know). Raw, basic, uncomplicated oats soaked overnight (in milk or water) with a handful of nuts and half a dozen prunes are brilliant for controlling your hunger pangs though.

So, two weeks into my oats experiment and I find I can skip lunch quite easily.

Thanks for posting that. A timely reminder to switch to my "winter breakfast". I need to drop a few pounds, so oats it is...
