They're getting there...  Looks like only 8 will be showing up now.  One teammate is completely silent and doesn't seem aware that there were challenges.  Here is the current loadout:

Characters 1-2 (burpees) - 6/9
Characters 3-4 (ruck p-ups) - 5/8
Characters 5-6 (bodybuilder) - 4/7
Characters 7 (10mi run) 6/6

Since we're down to 8, they have been given two exercise submission opt-outs.  Meaning that they have four to skip.  Meaning they need to do five more submissions and they got this.  Here is what they have decoded so far:

_ _ _ _ _ _ i _, with the last character being a number between 0 and 9.
