I think i wrote it a bit misunderstanding. ( Sorry im not a native english speaker)

Up to this point i have no issues completing all reps with good form. I am a bit stiff and sore for two days after.

So i am wondering if i should keep the intensity so that i can complete 10 explosive reps or should i do something like walking lunges for maybe 20-30 reps?

In my understanding this kind of movements are specific to RUNNING uphill and i was thinking that maybe some more powerhiking specific and less explosive but longer duration movements are better to my needs. But now when i think about it, these explosive movements will help me on the downhills and i plan to run all the downhills, and the powerhiking uphill with almost no additional weight is more an endurance component rather than a muscular one.
