There are many different names for V-ups but there are only a couple ways to
perform them and it really depends on the individual. For those who are not
overweight, it is possible to lift both feet and arms to the center while only a
small portion of the butt and lower back are in contact with the ground. For
those who are carrying extra weight, only a small portion of the shoulders and
legs may be able to get off the ground.
If performed optimally, the v-up is a great exercise for the entire
abdominals. V-ups can be used at any point of an abdominal exercise program but
since they can incorporate heavy hip flexor involvement, they should be followed
by an exercise with the antagonist muscle groups such as one of the lower body dynamic
flexibility exercises.
