This workout is based on Alex Leonidas' old school workout. In this or his intro to chest expander video, Alex says you add a spring to a particular exercise for your next workout if you have achieved one of 2 milestones: 2 sets of at least 12 reps, or one set of 15 reps. The first requirement does not seem to work for me. I have never been able to complete one rep with an added spring, in the very next session, after achieving 2 sets of 12+ reps. I went up in springs for some exercises early in this chest expander training bloack, due to gains from previous training blocks - the most recent 8-week Easy Muscle block, the 6x6 IsoMax block before that, and so on. I think the other milestone - one set of 15 reps - might turn out to be the more accurate one. I am wondering if I do 2 sets of an exercise, and can do 15 reps in the first set, if it matters where or not I can do 12 reps in the 2nd set.
