On P90X3 "The Challenge" if my numbers prove too hard to keep going by halfway through the total workout is it OK to switch to assisted pullups/knee pushups to make my numbers? Or should I back the numbers down before I start so I can make the totals even if I have to rest for a second? What I did for my first week was pause, continue until I had to pause again, and used knees as a last resort if I couldn't bang out the last 2-3.
Also, and I know this sounds lazy, is there a meal planner website where you can enter your macros and calories and it will suggest whole day menus? I don't have the internet at home so tap and track is a pain as I have to write it all down and enter it over lunch at work. I'd like to have a site that will plan a day ahead of time for me so I can print it and plan a whole day ahead and not have to track all day long.
