Pop pilates is actually a channel on You Tube. The fun, bubbly, encouraging instructor, Cassey Ho, brings pilates right to your own living room for free! She posts new videos weekly! She is so much fun and does her routines to current songs! She posts a weekly calendar as well so you know what videos to do that day for your workout! Videos range from 4 mins to 30 mins so depending on the time you have you can mix and match to build your own workout! I highly recommend her! She is the best instructor!
