Great info… but I have a question…

When Cal says that the actin-myosin filaments tear apart during a heavy eccentric bench or squat and then are cleaned out and repaired by the immune system so that during the concentric phase they’re bigger, thicker, and stronger to produce more force… is he speaking about the repair happening from between the eccentric 2-3 week phase and the 2-3 week isometric and 2-3 week concentric phase, or is he talking about an immediate change between the eccentric, isometric, and concentric phase of each individual rep.

I would presume it’s the former, but the way he said it, it almost seems as though he’s saying it’s within each rep.
