Now i am going to demonstrate one of my favourite endurance exercise for the abs. Super crunches
with the medicine ball. Okay, take a four pound medicine ball you gonna bring it to
the exact ninety degrees, okay, and you want to try to built speed take the ball, put the
ball on, take it off, place it on your feet so come up as high as you can, take it off.
So the key is to built speed as you get the hang of it. so the ball doesn't roll back
down, keep the legs level at that ninety degree angle. Exhale each time you come up to do
that crunch. Do about twenty rounds if you can, goes pretty fast because you don't super
crunches here, and also you properly execute super crunches with the medicine ball.
