"I believe that exercise and fitness are crucial to each and every individual's physical, psychological and emotional health.  Focusing on the mind-body connection, I strive to offer my students a positive yoga experience that will be challenging but accessible and leave them feeling energized and focused.  I feel that it is important to develop good fitness habits early in life and love to work with all age levels ? from toddlers on up!" - Checka

Jim Costa
Jim Costa's hometown is West Newton. He attended Boston College where he received his BS and MBA. Jim has 12 years experience teaching. He is certified by C.S.C.S. /ACSM/AFPA/AEA. Jim specializes in water aerobics/hydrorider, strength and  conditioning and is in the process of getting his ATRI certification (Aqua Therapy). Jim's hobbies and interests are; water sports and competing in triathlons.
His  training philosophy  is having a positive attitude and reaching out to those who need him. A sensible and moderate approach to exercise continues to be my watchwords in fitness, especially when you are working with individuals new to exercise. Breathing and movement continue to be my mantra. My focus is  to encourage smarter, kinder, more diverse workouts. It is my hope that this type of approach will motivate a larger segment of the nonexercising population. The one size fits all approach is out. Jim also says, "As the fitness revolution continues the no pain, no gain approach can beboth  injurious and intimidating. It is my belief  that a more moderate, more enjoyable brand of exercise that brings fitness within everyone's grasp can create an experience that can be enjoyed for a lifetime.
Education combined with hands on experience dominates my training regiment. 
Kick up  a notch!
