Thank you! Very helpful and comprehensive description. Easy to find online after listening to an online interview about its benefits. 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!
