AX1:  20 Up 20 Down Challenge

The name sounds simple enough, but that’s where it ends. The “20 Up 20 Down” Challenge is a real grinder that will expose weaknesses you didn’t know you had! This 20 minute test of wills may seem easy the first few rounds. By the middle, you’ll be wishing it was the “10 Up 10 Down” Challenge instead! Things aren’t always what they seem to be with ATHLEAN-X, this challenge is one of those cases!
