  1. Thank you! Very helpful and comprehensive description. Easy to find online after listening to an online interview about its benefits.
  2. Being a bit of a math geek and having done some tutoring, I believe you have an algebraic error in the document.
Your current version has:
Total interval time: 28 minutes (4×4 + 3×3)
Not quite right. The expression in parentheses is actually = 25
That does not match the desc. later on.
It should be 4(4+3) or 4*(4+3) for the interval segment, and the full workout expression would be:
10+4*(4+3)+10=48
with all units in minutes.
That quirky detail aside, I'm still going to add the workout to my weekly lifestyle.
Thanks again!
