App

There is an iPhone and Android app for the YAYOG programs. See Mark's website.

Some discrepancies have been identified between the app and the book (ref):
 * Heads up if you're using the android app - Basic programme, Weeks 5 & 6 Day 2 - second exercise in the last pair should be squats with a 3 second hold, not EVEN MOAR 1 legged RDLs
 * 1st Class week 1 & 2 day 4 should have Toyotas instead of Side Jumps too.
 * Basic W5/6 D4 - 3rd pair should be hanging leg lifts w/ knees bent, not more supermen, er, supermans. strangely it says supermans for these but says hyperextensions for the 2nd pair - both with exact same photo and description
 * Basic W7 D2, 3rd pair - should be 1LegRDLS instead of 1 legged squats
 * Basic W8 D1 (Tabatas) is missing the 3rd exercise, which is Burpees with hands elevated about waist high
 * Basic W8 D3 (Supersets), the last primary exercise should be let me ups with straight legs and reverse grip (instead of a 4th set of let me ins)
 * D4 two lots of beach scissors should only be 1? - Pretty sure it's because you have to do beach scissors on both sides
 * (devcide might have more details?)

The default for ladders is to only go up to 4 -- i.e., 1-2-3-4-3-2-1-2-3-4-3-2-1. The app will let you go higher with the ladders but you have to set it to do so! (ref)
