Trx?

[Dogmama]

I did TRX for my core with the help of a coach. Wow, it's a workout. It definitely strengthened my core and was more fun than just doing floor core work. I think it's more beneficial if you have a coach to help you at first so your form is good.

I'll need to hunt around to see who is experienced with TRX. Just watching the trainer at the gym, it's apparent that there is a lot to learn.
