So I have been doing yoga for about 9 years now. It is my favorite form of excersise. I am a pretty lazy person, so yoga works really well for me. All I have to do it a few stretches and pow! - I am fit! So I have started doing home yoga instead of classes because I am lazy & poor. I have been doing sun salutaions three times a day: morning, afer work and before bed. I can already see the results. I am getting toner, leaner and have tons of energy! Please give it a try- it can't hurt to at least try improve your life. GO! namaste!
