My files are structured to be modular whenever possible. Therefore, you can mix and match files as needed, but make sure to play them "in order" - never put Body 2 before Body 1 in a series. Take stretch breaks and try not to listen for more than an hour or two at a time. You can always come back for more. All of my files are either gender-ambigious or have male/female versions, so don't worry about getting left out.
