Lastics Classes

In the heart of New York City, Lastics is where people of all ages, levels and body types go to loosen up.

Our classes are never overcrowded and always filled with people who share a passion for wanting to feel good in their bodies. From people who are healing from an injury, conditioning for a sport, training for a profession in dance, gymnastics, skating, etc..., looking for pain relief, advancing a yoga or Pilates practice or just plain interested in being more flexible, all are welcome.

"I love Lastics because it takes into account the entire body and not just the part being stretched.  It is intelligent stretching that builds strength, alignment and overall movement quality. I do an hour of Lastics and then teach a dance class able to demonstrate choreography free from worry about injury." 

Mimi Quillin
Bob Fosse Dancer

"Lastics is a great way to prepare your body for any kind of movement. Within one class I saw a huge improvement in my flexibility, as well as my balance and control. This truly works wonders!" 

Marina Micalizzi
Billy Elliot on Broadway

“I found muscles that I never felt before and was much more limber than usual afterwards."

Randy Foye
Brooklyn Nets, NBA

"Lastics has been completely new and rewarding experience for the Joffrey Academy students. It has helped them think about using their muscles in different ways in ballet class as it incorporates exercises that both stretch and strengthen muscles."

Anna Reznik
Academy Artistic Director, Joffrey Chicago

"These exercises actually do what all the other exercises say they do, but really don't. I do a lot of yoga and used to be an athlete. Lastics was the best stretch I've ever had, bar none. You won’t believe how good you feel afterwards."

Hoyt Richards

"It’s definitely a different approach to stretching that works. It released the gripping I’d been feeling for years in my lower and middle back."

Dr. Andrew Feldman, M.D.
NYU Hospital for Joint Diseases, Associate Professor of Orthopedic Surgery, New York Medical College and Head Physician, The New York Rangers
