The 2-minute cross-leg reverse crunch

00:07.940 --> 00:09.996
is an assessment of core endurance .

00:09.996 --> 00:12.107
You will lie on your back on a flat ,

00:12.107 --> 00:14.107
level surface , legs straight , and

00:14.107 --> 00:16.218
feet on the ground . Arms are crossed

00:16.218 --> 00:18.107
over the chest with open hands or

00:18.107 --> 00:17.860
fingers touching the shoulders or upper

00:17.860 --> 00:19.916
chest . Hands can't grab the shirt .

00:20.149 --> 00:22.316
The use of an exercise mat is optional

00:22.316 --> 00:24.459
for this exercise . While keeping the

00:24.459 --> 00:26.515
lower back on the floor , bring both

00:26.515 --> 00:28.570
legs toward the chest while reaching

00:28.570 --> 00:30.570
your left elbow across your body to

00:30.570 --> 00:32.792
touch your right thigh , then return to

00:32.792 --> 00:32.700
the starting position . This is counted

00:32.700 --> 00:35.549
as repetition number 1 . While keeping

00:35.549 --> 00:37.549
the lower back on the floor , bring

00:37.549 --> 00:39.382
both legs toward the chest while

00:39.382 --> 00:41.493
reaching your right elbow across your

00:41.493 --> 00:43.549
body to touch your left thigh . Then

00:43.549 --> 00:43.189
return to the starting position . This

00:43.189 --> 00:45.950
is counted as repetition number 2 . The

00:45.950 --> 00:48.172
repetition will not count if your hands

00:48.172 --> 00:50.172
or fingers do not remain in contact

00:50.172 --> 00:52.006
with the shoulder or upper chest

00:52.006 --> 00:51.990
throughout the assessment , including

00:51.990 --> 00:54.729
the rest position . Additionally , the

00:54.729 --> 00:56.951
repetition will not count if your lower

00:56.951 --> 00:59.118
back lifts off the ground , your elbow

00:59.118 --> 01:01.285
does not touch the opposite thigh , or

01:01.285 --> 01:03.507
legs do not fully extend when returning

01:03.507 --> 01:03.450
to the starting position . The resting

01:03.450 --> 01:05.283
position will be the same as the

01:05.283 --> 01:07.339
starting position . While performing

01:07.339 --> 01:09.561
this exercise , your head does not need

01:09.561 --> 01:11.672
to touch the ground . If you move out

01:11.672 --> 01:13.783
of place greater than 1 ft , you will

01:13.783 --> 01:16.006
be warned , and if it continues , those

01:16.006 --> 01:18.228
repetitions will not count . Your final

01:18.228 --> 01:18.139
score is the correct repetitions

01:18.139 --> 01:19.279
completed at 2 minutes .
