To quote the great Disgusted: "There's only so many ways you can push and pull with your arms....".

No magic machines is going to overcome your genetics limitations.
Work hard but work smart. Don't waste your time doing insane "machine" shit and other idiocies. Time is limited on this planet until further notice.
Enjoy it the best you can. Be productive, be happy.
