In this video Cathe and the XTrain crew say a quick hello from the set of XTrain on the first day of filming. This was just a spontaneous video shot right after the filming of XTrain Chest/Back and Shoulders. Cathe introduces the XTrain crew for this workout and you can also see what the outfits look like and you can see part of XTrain video set . This time we’re back in the loft like we were in STS, but this time the video set is in Philadelphia instead of NYC.
