Now that I'm home it's back to regularly scheduled physical therapy. Did something new today -- yellow band around the ankles, then alternate feet kicking to the side and to the back. My PT was slipping the band over my feet when I noticed the yellow color looking quite awful with my black pants. Said, "Eww, Hawkeye colors!" He laughed and asked if I wanted a red band. I think he was just kidding. I said no.
(Just FYI that colors denote resistance force: "Red resistance bands are medium to heavy resistance. They have a higher level of tension than green or yellow bands and are harder to stretch. Red bands are suitable for muscle groups that are larger, such as the legs, chest and back, or for individuals who have been building muscle strength.")
