Hi Morten

What is your opinion on Kaatsu exercises for children age 10-12 years?
Not sure I think it is a good idea, but I have a patient asking..
Have googled it, but cant seem to find any information.

I use your app for my PE classes. I love it. I would like to see you add curl up, pull-up, trunk lift, shoulder stretch and flexed arm hang. If it is possible to add these it would be fabulous.

Chris -> I see your point, but for this category of estimation there are already many uncertainties as we are not really measuering anything. We could make it more accurate by asking for a VO2max value, heart rate, maximal heart rate and other measures, but then it wouldn't be easy to use at all. So by asking for a 10 minute setting we feel that it is a fair balance between ease of use and precision. Also, with a 10 minute dial you can maximally be 5 minutes off ;-)

Hi Morten,

I really like the design of your calculators and the ease of obtaining a result.

One question though regarding the advanced energy expenditure calculator. It is described as "very precise", but the increments available are only in 10 minute segments.

So, a 10 minute change in intense activity for example is for me about 250 calories or roughly 10% of my daily calorie allowance.

I guess there is a trade-off between usability and precision, but does this make for a "very precise" calculator?

Thanks,

Chris

You probably entered your height in meters whereas it should be entered in cm.
175 cm that is and not 1.75 cm ;-)
