Glad to see more noobs take the challenge! 
Can't wait to see the results! My suggestion would be start by going for the 20/20 and work your way up. I tried going straight for the 40/40 being all macho and cocky inside; you know how us men get!, and laughed at myself after trying it the first time at 10/25, which added some humility in me, and I went for the 20/20 and did it.
So trust me, save the time on the macho man stuff, and start small!
Suspension training will introduce muscles you never knew you had! But most of all, have fun!
