Purists be damned —whether you want to tighten your butt, confuse your muscles or melt fat, the new fusion yoga will give the Oxygen gal exactly what you need. Here are six worthy options to try.

Today more than 20.4 million Americans practice yoga, according to a study by Yoga Journal, a 29 percent uptick from 2008. And little wonder why it is on the rise — the health benefits have been widely reported for both body and mind. In fact, just 20 minutes of Hatha yoga has proved to significantly improve concentration and working memory, according to a study published in the Journal of Physical Activity & Health. As its popularity has surged, so have offshoot hybrid yoga classes — melding traditional yoga with a melting pot of activities such as ballet, kickboxing, boot camp and stand-up paddle boarding offering full-body strengthening, shape-shifting and cardio-pumping sessions.
