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).
Well, ideally you would use measurable actions to track. For instance, your maximum plank time should increase over time if you are consistent. However, if you started out planking 30 seconds or something and after a few weeks of training abs/core you can still only do 30 seconds, then you need to adjust your training. You may need to add more volume or more exercises.
