Pilates and yoga are great for your mind and flexibility but if it’s weight loss you are after then you are doing the wrong thing! Your heart rate does not get up high enough to burn big calories. You will burn calories depending on the type of class ( a typical hot yoga class can burn up to 300 calories) but compared to an indoor cycling class where you can burn up to 600 calories. You simply have to get your heart rate up to burn those calories fast!
