Dr. Rachel Skolnick, D.C.

“It’s easier to hold, comfortable and more effective to use than straps, bands and towels which exacerbate arthritis. Both my professional dancers at Juilliard School and my Upper East Side seniors with chronic pain LOVE CastleFlexx.”

"The simplest way to put it was, 10 minutes of doing a simple Pendulum stretch with CastleFlexx, my heart rate went up 20-30 beats and I was in a full body sweat and I remember thinking I've never had this with yoga, pilates, acupuncture, hot/cold baths - CastleFlexx in 10 minutes got me there."

Dr. Adam Miller, D.C., CCSP

Chiropractor for the New England Revolution

"CastleFlexx is a product that I use daily, nightly, especially with training where my muscles have been killing me, on my hip flexors and lower back - it does tend to make a huge difference."
