I've never focused on Pilates for upper body work, so I can't comment on results. I've done Pilates upper body work from time to time when I feel like doing something different (I usually do Cathe or the FIRM). Light weights are used for the exercises, and they are harder than they look.
I don't have the Winsor upper body video. I do, however, know of a few other tapes that have Pilates upper body segments. These tapes are cheaper than the Winsor tape and contain other segments in addition to upper body (they are all available on DVD and VHS). You might be able to get them on the VF exchange.
Method Dynamic Toning has a 20-minute upper body sculpting session and another 20-minute segment for the abs and lower body (mostly abs). The first 20-minute segment of the video is called "total body toning", but it's mostly stretching with a little core work thrown in.
New Method Precision Pilates has three ~20-minute segments: upper body, lower body, and stretching.
EDIT: I don't remember if the upper body segment is a full 20 minutes long. I traded the DVD because I didn't like the picture quality and the music wasn't loud enough. :rolleyes: I tended to use my other Method workouts more often. The Precision Pilates workouts are pretty good, though.
Precision Sculpting has both upper body and lower body work. I don't have this video, but I plan to buy the Method Precision Toning/Sculpting DVD after watching clips at Collage.
Hopefully someone else will comment on the effectiveness of these exercises!
