Several of us did a 4DS check-in that eventually became "Waiting on STS" and is now STS & Beyond.
I really enjoy 4DS (need to get it back out, though). It is flexible, has the most number of premixes I've ever seen, has excellent chaptering, great videography, and is a series that a few dismissed early on but later fell in love with after giving it a whirl. I think it's a great series! The only workout I have not ever tried (
) is HIS but I just haven't taken the time to learn the choreography. I LOVE LIS and the Kickbox. Bootcamp reminds me of elementary PE stuff - but way more fun with the Cathe gang - and with music!
