yeah it was slow on the concentric because it was heavy 
i did put all i had into it. But your right, the shoulderblades kind of dident feel right, it was ackward with the plates on my chest, i think next time i might use a belt to keep them still under my shirt. And about the arch, i dont know why i dont use a bigger one, ive tried it before, but i dident feel right, my back kinda hurt afterwards, im benching at the gym today, ill try a few different approaches and see how it goes, ill film them too.
And with the GMs, i think its because im tall, my legs are the long part, specially my femurs. The upper body aint that long.
