We had Masako lead an exercise class of about 20-25 people for our apartment residents. She was professional in being on time, preparing a thoughtful minute by minute exercise circuit and pushing our residents to their limits. The group had a wide range in age, from early 20s to late 60s, and all in different physical capacities for exercising but Masako did an excellent job leading the whole class in endurance and strength training. She is a no nonsense trainer and has plenty of experience in being a fitness trainer. If you're looking to get in shape quickly, then Masako will help you get there. - Audrey P.
