The Modern Improvement Club is a new gem on Long Island. The Hot Flow Yoga and Total Body Fit classes I have taken have been wonderful. I can't wait to take more classes. The instructors and staff are friendly, approachable and knowledgeable. The owners, Steven and Laura, are terrific and really try to get to know the members. They have clearly sought out the best instructors on Long Island. Great smoothie and food bar and amazing workout clothing.
