I also have to make adjustments depending upon my activity. for rollerblading the best placement seems to be on my forearm, and when walking on my calf. I have to give another go at biking to see what would it would work out to, when I do I will be sure to include the info in my post. I am so hoping the fitbit integration happens soon as I think that when I am doing things like raking and shoveling snow this will be the most accurate method :) <333 Thank you so much for staying actifit & sharing your journey (and tips!) Much Love!
