I remember reading on the forums that 5 risers are needed for each side of the step for STS SC...is this the final confirmed #? Just want to make sure since I'm writing my Christmas list out as we speak!
I think at one time they posted some pictures where there were women jumping up on to a step with 5 risers on a side, but when I've looked through the photos I haven't seen this number of risers. On the HIIT photos I see 4 risers to a side...so you might be alright with 8 total. Hopefully someone who is "in the know" will give you a more informed answer than mine.
