This morning I attempted mastery on MN/PE2 (Straddle-up), as it was my first time trying this exercise.
I performed 5x15 reps of the best form that I could - but I felt quite limited in my ROM both in my straddle (I don't have the active flexibility yet to raise my legs very high off the floor), and in raising my chest - I felt like I was leaning back at the top of some of my reps.
My question is how to proceed in gaining the ROM in order to master this movement - should I start a 4 week cycle (starting at week 9) and simply repeat until I test successfully? I feel like if I started at Week 1 or Week 5 that I won't be getting the volume that I would need to encourage the increase in ROM.
Should I supplement this movement with extra mobility to quicker gain the appropriate ROM for this movement?
Any help would be appreciated.
