worst workout ever....why would design a workout solely relying on crunches? why won't you consider variations?

My favorite was the bicycle crunches my least favorite was the crunchy frogs.

It was pretty easy for me. I liked it

Too fast to follow. At least he should teach the exercises for a few seconds before jumping in.

one of my fav

Amazing

Horrible workout. It changes every 20 secs and you can't keep up with it

Wow! Loved it!

This was my first workout and it was an amazing ab workout. Thank-you!!!

Very nice
