Consider this: your body can only apply as much force as your grip can withstand. If your hands can’t control the bar, your power leaks before it even transfers through your arms and torso.

 Eating hundreds or thousands of extra calories is often "absurd" because the body can typically only generate three to five pounds of new muscle per year, making massive surpluses unnecessary. Rather than traditional bulking, a "maingaining" approach focuses on keeping body fat levels neutral while progressively increasing strength on key lifts over several months.

The longer we're spending in that stretch position actively lengthening and relaxing those target muscles we are going to be spending more and more time in a lengthened position but also getting further into that stretch position which is going to leave us more mobile than when we started. Now these are going to be more effective for mobility than traditional static stretches as well because we have the external load helping us.
