How can I play volleyball and wear the Apple Watch?

Often times, I find myself taking off my Basis B1 Watch because I can't use it when I play volleyball. I can't use the watch when I do back flips, and I can't use the watch for any activities which is extreme that may damage or cause the watch to come off. I can't use my B1 for doing pushups because my wrist bends and causes unnecessary tension on the wrist.

Given the ability to use different straps. Is there a strap where I can move the watch to my leg or another part of my body and still be able to get my pulse and steps correctly? The linear movement on a leg is far different from being on the wrist. Will it know that the watch is in a different location on the body and adjust correctly? Is this detection automated?

BTW. I love volleyball! I can't imagine playing my favorite sport and not being able to collect any data about it.
