Hi Ken, i m also working with calisthenics 3.
At first it seemed really confusing.
Now i m working just with 3 and b7 : enclosure from below and above descending
enclosure from below and above ascending
enclosure from above and below descending
enclosure from above and below ascending
Only after i go and do the chromatic enclosures, following the same order.
Offcourse for each exercise do it in all 3 patterns.
This way i find that i dont loose track of my 3s and b7s.
I m going to do this for a week or so, only then will move to 1 and 5 doing the same stuff.
hope it helps
cheers
Miguel
