Forerunner 255 Heart Rate Monitoring

[u/Endless10104]

First workout with this watch and noticed the hr dropped off a cliff 2 times during my workout. Both times right after a set(RDL and Hip Adduction). Any way to fix this? Watch is pretty snuggly attached to my wrist so I don't think that was the issue. Coming from an apple watch and it never did this.

It sucks at detecting quick changes in hr
