Those of you who have these workouts: To what extent is the step used? My sister is interested in starting some weight lifting videos. She is experienced at lifting, but doesn't have a lot of eqipment... or room to store it. Is it used like a weight bench only? Could a stability ball be used instead (as a weight-bench replacement option)? She is especially interested in SL & RTTC.
Thanks in advance for any info!
