Day 22 - Today was short but significant workout. I tried slacklining for the first time. The workout was 25 minutes with an average HR of 108. Slacklining is simply putting a line (in my case 3 come-alongs strung together) between two fixed points and trying to balance on it, tightrope style. After 25 minutes of trying I was able to stand for about 5 seconds at a time.
