Strength & Balance class is focused on moving with great intention and strategically exercising certain muscle groups and stimulus. For example, we will start with a warm up, move into balance training, then upper body exercise, then finish with core and stretching. Exercises are designed to improve balance, build strength, and reduce pain.
Endurance Circuit class is a faster paced cardio class. We use the machines (rowing machine, stationary bike, sled - and many more) and make our way around various stations. Exercises are designed to improve cardiovascular fitness, stamina, and endurance.
