Hey i did my first lvl 1 workout today :) I had some confusion about the set system like it said *Sets= A number of reps done in a row with no break* so i did that and it had me very confused.
Australian Pull ups 3-5+max 4-10 100
Dips negatives 2-4 4-10 120
Regular Push ups 3-6+max 4-10 80
Squats 4-6 15-20 100
Wall sit 2-4+max 20-60 sec. 80
Crunches 4-10+max 10-20 60
Plank 2-4+max 20-60

The seconds system to! Ive watched Christian's Vid about it but i cant wrap my head around it. Help from any out there?

Basically a rep is self-explanatory: repetitions. So if you need to do 1 rep, you do the exercise 1 time (1 squat or 1 push up), if you need to do multiple repetitions, say 10, you do 10 repetitions/do the exercise 10 times (10 push ups). So looking at level 1, after you've done 4-10 push ups (required amount), you have the rest time of 80 seconds, and then you continue the 2nd set of 4-10 push up repetitions, then you have rest time again, and then 3rd set. So you need to do minimum of 3 sets which depending if you do minimum (4 reps) or maximum (10) reps of push ups, you'll need to do a minimum of 12 (3 sets * 4 repetitions) or 30 (3 sets * 10 repetitions). Hope we explained it good. :)
