If a completely developed, flat and toned abdomen is on your fitness wish
list, the BOSU twisting crunch should be in your exercise program. By using
the rounded surface of the BOSU for your back, you allow your abdominals to
go through more range of motion when compared to a floor crunch. This allows
BOSU twisting crunches to thoroughly work your abdominals, core and obliques
in a single set.
The standard BOSU crunch should be mastered before attempting this
progression. The exercise gives an extremely intense burin the abdominal region
so it is a good idea to perform supermans, the BOSU cobra
or some exercise for the antagonist in between sets to stretch out the
abdominals in addition to working the target muscles. The BOSU twisting crunch
is a great addition to any abdominals workout program.
