I think it comes down to the adaptive response. Is the duration of hold necessary for the stretch overload or can it be substituted for increased tension?I try and actively pull shoulder blades together throughout the bottom of a pushup hold....although you nailed it when you said force production would drop.
I have been giving some thought to the volume you could use that could make each set doable and avoiding failure....
Something along the lines of - if 2 minutes was your max long lunge hold time, then performing multiple sets of 1 minute. Maybe 4 sets of 1 minute.
It's a work in progress .... it also continues the debate that is as old as time. Volume or intensity haha.
Have been really tinkering with the eccentric iso currently. Eg OHP, line up with hands just under shoulder height, straps anchored behind you about 2 feet, shoulder width apart, knees bent in a 1/4 squat, lean forward a little. Reasonable stretch on the entire delt similar almost to a behind the neck press.
Exert about 70% effort and bend the knees, lowering while extending the hands up (staying in same place). Get to about 1/2 the ROM of a full press, and drive back up with the legs, resisting 100% as the delts get lengthened back out.
Not sure what to call these, but they def seem to be generating a solid response. I still include the static holds and pulse shots.
