In an effort to allow my persistent running injuries to heal but not abandon training altogether, I've taken on a couple of new endeavors. The one most outside of my comfort zone is Tampa CrossBoot . This is a type of training that, to quote the website, "embodies the camaraderie and team effort of fitness bootcamps and the strength and conditioning concepts of CrossFit." But since that doesn't tell you much if you're already unfamiliar with those two types of training, here are some highlights from my first class: I forgot how to jump rope.
