Bodyweight override when I do workout

Hi . I set my current bodyweight on my profile to 87 kg . From days a go , Im saving my current bodyweight using “Set data” , so , I save for example 87,5 kg in the morning . On the aftenoon I do my workout and this override my day bodyweight to 90 kg ( I do not know where comes this 90 kg ) and this delete my 87,5 kg saved in the moring. Why?

Check which sources are configured for weight import. One of them is sending a static weight.
Intervals itself will only set the weight to the last known weight on days with an activity when the weight field is empty for that day.
Could be Garmin, Strava, …

Yes ! you are right . It is from Strava . But anyway, this override my bodyweight each day . Im saving my bodyweight each day.

If you have “Update weight from Strava” ticked in /settings then you weight is pulled from Strava whenever activities sync overwriting anything you might have captured for the day. You need to untick that box.
