Hey Omega, just going through the articles, planning on starting tomorrow. Anyway, after reading this, I have 2 Q's:
1. I understand what it means to flex at the top of the movement, but when you say "sustain that flexion through the actual exercise" do you just mean to keep it tense. For example, you flex the muscles in the bench press at the top/positive movement then during the negative just keep that muscle tense on the negative... basically tensed throughout the entire set. Is that right? Or maybe you can further elaborate?
2. You say the first set should be 20 "real" reps... that it should fatigue you and pump blood into the target muscle. By "real" I assume you mean somewhat challenging? I usually do between 5-7 reps on my routine, so from that perspective, if I can lift a weight for 6 reps.... do I do 50% of that weight? 70% of that weight? After I do 20 reps with this weight, I should feel fatigued? Like should I feel a "burn" (lactic acid) should prevent me from doing any more reps? And, is this also following the same rep tempo of 2 sec. up and 2 second down? Just wondering since usually "warm ups" are a bit faster tempo than the heavier weights, and since this is 20 reps it would be much lighter of course.
