The ab equipment is great. It was partially but together with strap. I have only done the sit up and it works good. I can go all the way down and come back up without straining my neck. Instructions are included on how to complete 10 exercises step by step. By providing that, it gives an opportunity to not strain anything and do exercise correctly.
