One of Jay’s favorite series in all of the Pilates work is the Short Box and in this session he shares his knowledge of how Joe Pilates himself wanted you to practice it. He goes into detail from how to adjust the exercise for different bodies, to how to position the feet properly. Along the way, Jay points out the most important things to look for in the work, the body, and the apparatus, as well as options for teaching the series to folks who are new to it or have issues that might prevent them from doing the full expression of the exercise yet. Filmed at Vintage Pilates, West Los Angeles, CA.

    Another great tutorial! I can’t help wondering why I have been taught Tree so differently. The whole emphasis is different and Jay’s explanation of what you’re trying to achieve makes so much more sense. We’re taught an extra, Side Sit ups, with Peak Pilates too. Where has this exercise come from?

    I would like to see differences between short box series on the reformer and ladder barrel . When choose one or another ? Thanks

    As usual Jay, you are clear and consistent. Thank you for your brilliant teaching and preservation of the work.

    Wow, Thank you Jay. The short box is such a powerful series. Would doing the short box on the ladder barrel be as beneficial ?
    See you at Dana’s in October. I can’t wait!!
    Love you Mary Lyon

    Having observed this video several times, one of the things that has really struck me was the point made by Mr Grimes, that its “not about the height of the leg when doing the Tree exercise; its not a Karate Kick or the Can Can”.
    Although I can only practice it on the mat, I have so often observed this exercise being demonstrated on DVD and it appeared to me to be all about how high you could get your leg.Thank you for explaining in simple terms what this exercise is really all about and how to do it correctly.

    That was a very powerful 20 minutes of instruction and demo. The detail here was so incredible. Yeah, and great job Ken, really impressive scoop action, esp. when you were doing the tree.

    Thank you so much Jay – I love how you describe and teach the Short Box. So helpful especially the information about helping new students and particularly tight and shouldery ones. Good job Ken!

  14. Thank you Jay – i can really see how the exercises build upon each other in this demonstration – especially from the straight to the side to side. Amy

    I am not a fan of doing reformer exercises on the mat. In this case the body would be on a completely different plane, the angles would be totally different, and the range of motion would be severely limited. It would become a totally different exercise, and much of the benefit would be lost.

      Point taken and thank you very much for replying.

  18. joesmat 8 years ago

    Is there any reason this work cannot be done on the Mat which has a strap, although I appreciate you would not be able to duplicate the High Bridge (prep) aspect, as the height of the Reformer adds more reach for the arms and hand positioning? I hope the answer is yes, and I will build myself a box to the appropriate sizes.

    Mr “Ken” (demonstrating) you are a very lucky man having Jay as a regular Teacher.

    Thank you very much.
