High-intensity interval training (HIIT) has become a popular way to burn fat in the gym, but that’s not all this type of cardio training is good for. The essential framework of high-intensity interval training is always the same: brief, all-out work periods, separated by rest periods that you wish were just a little longer. But no matter how long you rest, the key is that you bring everything you’ve got to your intervals. This 30-minute training will help get your heart rate up, condition your core, increase your strength, and burn plenty of calories. Our HIIT classes are among the most popular for overall fitness.

One of the most crucial components to training for climbing is developing a strong core. This quick but intense weekly class will combine traditional core exercises with movements from yoga and pilates to strengthen your body in a challenging, well-rounded workout. Besides preparing you to send your projects, a strong core can also help to prevent injury and maintain good posture.


(Included with Day Pass or Membership)
Mat Pilates is done on the floor using a yoga mat.  Mat Pilates utilizes breathing patterns, specific exercises performed in a controlled, precise manner, and your own body weight as the primary source of resistance to build core strength and spinal stability. Learn to activate your deep core muscles in each movement for optimal strength.  Pilates improves muscle tone, body balance, spinal support, low back health, sports performance, and body-mind awareness.  Pilates is a safe yet highly effective way to strengthen, stretch, and streamline your body and improve performance in your daily life.  Appropriate for all levels, modifications given for beginners, pregnancy, and physical limitations.
