Drink isn't bad for you and BMI is useless

Hip hip hooray
How do you all measure your own fitness ? Does anybody else have a basic 'route' that they use to measure their performance ?
I can tell in the first 10 mins whether I'm on form for a good ride or not - but I haven't found a reliable factor / predictor. I've kept records of my ride performance after heavy nights out, various diets, different amounts of sleep, etc - but nothing tells me how well I'm going to ride until I've been out and warmed up. I thought my better figures would come after a week of good behaviour (?) yet it's not the case. A stinking night out obviously doesn't help but i've had a good session in t'pub and a portion of spare ribs the night before my best 60 mile run up hills without problem.
As far as BMI is concerned, as long as my belt keeps going in notches every few weeks I don't really mind what my BMI is

Aye, BMI's a complete waste of time - the other indicators that take waist / hip ratio etc. into account are better but as you say, it's how you feel and how your clothes fit that tells you the most.
I always used to think I could tell if I was on a fast day but I've found from the 'puter that what feels like a quick run often isn't and my PB on my commute was done on a day when I thought I was taking it easy! My response was to take the 'puter off and stop worrying about it, it's not like I race.Even if the voices aren't real, they have some very good ideas.0 -
BMI doesn't work cos if you have massive muscles then you will be classed as overweight when in fact you may be perfectly fit.
as shadowduck says hip to waist ratio is the way to go0 -
BMI is useful in statistical determination of the extremes of overweight and underweight. Its also a fairly safe indicator for the majority of the population (extreme mesomorphs excluded obviously!).
For general fitness you can use your resting heart rate and your recovery heart rate as reliable indicators.0 -

I use a power meter and actual performance to track changes in fitness.0 -
Resting heart rate descreases over time as fitness increases
Your heart rate recovery times should increase as fitness increases
These are indicators of how well your cardio excercise is going, i.e. how fit you are. Lower resting heart rates indicate a larger cardiac output which imeans that when you do start exercising, your heart doesn't have to work so hard. Recovery heart rate is linked in that, the quicker you can get your heart rate back down to normal, the stronger your heart is.0 -
A lower RHR is more likely linked to an increase in stroke volume and indeed a lower cardiac output at rest as fitness improves. However RHR can still vary quite a bit despite having the same fitness (as defined by max sustainable power), conversely, fitness can vary quite a bit despite the same RHR.
But in general, yes from an untrained to trained state, RHR does drop.0 -
So what should a healthy RHR be?...and is it fair to take it when I'm sat on my rse surfing the web in the office?

I believe the average is 73 or similar. So anything below that is good. I believe the recovery heart rate is more important as a determinant of fitness.0

What can be a more important indicator of fitness than actual performance (or power produced during that performance)?0 -

With the slight technical glitch that power meters cost a (relative) fortune and taking your resting heart rate is free.
Oh yeah, and how does having a greater stroke volume give you a lower cardiac output. The reason you get a lower heart rate with a greater stroke volume is to maintain the same cardiac output for less work. You still need the same cardiac output at rest no matter what your fitness, so as SV increases HR decreases.....
CO = HR x SV0 -
And another thing BMI is not useless. It is a very poor tool for judging an individuals level of obesity but that is not really what is was designed to be used for it is just what people have started using it for. It is a good tool for the study of whole population groups.0

I do a fair bit of sport coaching, and my preferred methods of fitness monitoring is a combination of all the techniques talked about here! I track RHR which is also a good indicator of incoming infections for dropping training (ie often your RHR spikes the day before you come down with a cold/flu etc.). Also I use sprint tests to exhaustion usually a 2K ergo, which is around 8-9 minutes long as well as repeat training such as repeated long ergs to monitor recovery ability.
The erg has the added benefit of a built in power meter, which makes everything easier. For cycling though I'd imagine something similar would provide a balanced overview.
However the monitoring of fitness is a bit of a moot point. I prefer constantly pushing myself, and not really worrying too much about the results.0 -
i don't like drinking beacause i feel it harms on our health. Alcohol is not good for us. If we can leave it it will be good for us. While many of the more serious health effects of drinking affect those who have been drinking for many years, it is feared that alcohol abuse during the formative years sets a pattern for later life.

I think you'll find medical statistics are not so clear about moderate alcohol consumption - many claim that it is good for you. The guidance figures were recently revealed as non-scientific and too general to mean anything. Exposure to alcohol in the formative years is also far from clear, although I had my dummy dunked in gripe water and that may affect my view on this. The physical problems with alcohol are possibly less than the psychological and societal ones so get the next round in matey0 -
But cutting everything out that is bad for us might not be a terribly good way to go, there is strong evidence to suggest that moderation is better than total exclusion. For example with peanut allergies, some evidence points to increased sensitisation as a result of exclusion during the early years. Equally the increase in asthma levels has been hinted to be as a result of increased cleanliness hyper sensitizing our immune systems.
i freely admit that some things are so harmful that they ought to be completely excluded, but the vast bulk of things that are "harmful" do not need to be removed.
To go the other way, most people are slightly gluten and lactose intolerant, should we be all going gluten and lactose free?
Now I know that alcohol is more serious than some of the points that I've raised, but simply cutting it out because it is bad for you is counter-productive when many can a do enjoy it safely and in a controlled fashion.0 -
I saw a t shirt once, it said 'Dont drink, don't smoke, still die'. It was on some well into her seventies old lady doing a bungy jump. She had a point.0
