NOTE: Ribs should be always kept in the refrigerator (approx. 40 F/4.4 C) before preparation. 1  Take the meat out of the refrigerator. 2  Rinse in cold water. 3  Remove any excess fat and extraneous meat pieces, or stuff you don't want to eat.  Remove the membrane (on inner 1  side). Rinse again, pat dry with a paper towel.
Also, a recent study on 168 college students found that your average college-aged female has a plank time of about 1 minute, 30 seconds, while an average college-aged male has a plank time of about 1 minute, 46 seconds (2).
Holding the plank for 30 seconds on your first try is a respectable showing. The more you practice the plank the stronger you get. Add five seconds every few days to the plank until your core and arms get stronger. For non-couch worshipers, jump right in to the 4 Minute Plank Challenge and hold that pose.
