The symptoms of delayed gastric emptying include nausea and vomiting. Poor emptying of the stomach can occur for several reasons: The outlet of the stomach (the pylorus and duodenum) may be obstructed by an ulcer or tumor, or by something large and indigestible that was swallowed.
Heavy pulldowns build up your lats, biceps, and forearms, which are the exact muscles and range of motion needed to do a pullup, Duffy says.
