Is there a way to update my weight in my TrainerRoad profile automatically, e.g. from Garmin Connect or Apple Health, possibly through the use of IFTTT or something of that sort?
I have a Bluetooth enabled scale and can sync weight into Garmin Connect, Apple Health etc. already, but I’d like it here also.
Happy to write a few lines of code if there is something a Web API available!
Well, if you claim that weight gain = more power, I think many people can disagree (me for one).
Without direct attribution to where that gain is actually coming from (muscle, fat, combo?) there is no way to make any educated guess that is meaningful WRT to power estimation or FTP. And even if the gain is pure muscle, it could well be in places that offer no benefit whatsoever to actual power production.
Watts per kilogram are an obvious one that TR already handles (simple math from two known values via weight from user & FTP from TR AIFTPD), but if you aim to have TR leverage weight delta to FTP estimation it needs far more than a pure weight and delta to be of any real use.
A person who adds an upper body day to their strength training could well gain great strength there, but actually lose on W/kg since that weight offers no actual power/FTP gain. There’s just nothing simple when looking at “Weight” and “Power” other than the W/kg in that basic calc.
