Pilates, I had heard, involved archaic equipment with names like ''the reformer'' and ''the barrel,'' but that was about all I knew when I arrived at TriBeCa Bodyworks, a Pilates studio on Duane Street, determined to see if my bias was well-founded. A model-thin woman blew by me, a single line of sweat dripping down her radiant cheek. Great. I hated the place already.
Alycea Baylis-Ungaro, the owner of the studio, had instructed me to bring loose clothing and to wear socks. No sneakers were necessary.
Showing me to the changing room, she whispered, ''Even men do Pilates. We get a lot of them.'' It is true. During my workouts at least one-third were men. Besides, there is, as I soon learned, nothing feminine about Pilates.
