Hi all. I am planning to buy an Apple Watch 2, my main option is to use it for fit up. This means weight lifting. I previously owned Microsoft Band 2, which had some sort of sensor, which were able to detect this activity, and was able to log my HR, and count the weight lift. My question is, does this device has some sort of sensor, which can provide this information? Or should I look for other alternatives? Thank you, BR.
