HS/PE2 mobility variant

Hi everyone, I train at a park and I do not have any weighted bar, is there any variant for "Static standing shoulder extension with weighted bar" so I can do it with no equipment? or should I be considering buying one? I tried to do a variant on stall bar but its completely different, I have to push my arms in the opposite direction than in HS/PE2 

HI Mario, unfortunately nope. you cans still grabbing with you a wood bar and a 2 kg plate. it's not expensive or space consuming.
