You need to sleep way more. And I'm pretty sure eat way more too as I'd guess you don't eat much. You are a stick amongst other sticklike asian ppl. However, a very strong stick.
While I can run on a biphasic sleeping schedule, 3.5+2-3, it ain't fun not even with 5+ in the first phase. Little naps help but it still sucks for working out imo. It might be ok for a pure strength modality if I could get past the WU when I'm that sleepless.
I figure the cross hurts simply because you don't do it much anymore.
How clean is your press to HS?
