thanks for the chart. I miss 305pelusa perspective, a very valuable member of the forum! I am somewhat agnostic (to reuse from thread on nostalgia) re hypertrophy range for reps and TUT. My use of Clusters and now Iso is having me simply do and record impressions.
I should say is not a case so much of zero or maybe even declining hypertrophy, as every muscle is now becoming acclimated to Iso I am possibly losing some stored glucose and water in the muscle - to me I look like I've lost weight from my start of 192lbs. But...when I test or do actual work during my day I tend to generate a pump at much lower threshold of effort, whereas before nothing I could do in my daily would come close to the effect from resistance training.
It was my theory coming into this, that hard effort Iso would create a delayed state where the muscle is ready to draw blood at much faster rate/lower threshold at commencement of dynamic exertion compared to same muscle post isotonic exercise.
I did some 35lb loaded crunches last night and hit 20 side to side variant (up and to the side, pull side to side 3x with shoulders as far off the floor as I can contract, and back down keeping shoulders parallel to the floor throughout), they are not quite as difficult move-for-move as 4 regular crunches but closer to 2.5x when I do side by side comparison. These engage serratus and oblique to a greater degree.
20 is about where I left off from sandbag so maybe not so much improvement as other muscle groups or maybe stronger at bracing and not as much dynamically. And now this morning my abs are visibly more defined...AS far as experiments go, this is generating as many questions as answers.
