Lil .. I'm still a long way away from being able to do that kind of a workout ... even a short one, but it's what I'm thinking I'll get once I get to that point .. (primarily because of the joint friendly issue) ... I'll look forward to hearing reports about that issue.

Right now, for me, I'm just trying to incorporate some extra steps into each day ... I do 45 minutes worth of totally non-impact and not really aerobic stuff 4-5 days a week, it tones and at least I'm doing something, but the just started this week with working to start toward building my capacity with some walking (and I do mean a few extra steps at this point)!!
