5':10'' lower plank record.

Yesterday I reached the 5'10'' mark while holding the lower plank position. It is a great achievement. I must confess that it was tough, especially given that the shoulders and arms were giving in, the chest was sore, and my hip wanted desperately to touch the floor, but I managed to stay in the lower plank position for 5 minutes and 10 seconds.

Other achievements are more cardiovascular, like running 10 miles fast(did no count time), 80 jumping squats after other workouts, Spartacus, and so on,.

Low plank position.

The low plank position, also known as the elbow plank position, is obtained by bending the elbows  and placing the arms perpendicular to the floor, while supporting the opposite side with the tip of the toes(or metatarsals), maintaining the back and legs straight. It is a challenge after ~2 minutes if one is fit.

Of course the biceps triceps and quadriceps are worked, but the core, especially the transversus abdominis is the most benefited from this exercise. My record is 4:30 minutes but it keeps increasing as I continue gathering sessions. One series every other day can help one improve the sitting posture, let alone the abs and arms workout.
