Cathe Live - My favorite by far! I have been a subscriber from the beginning and will always renew.
I do it every week and repeat my favorites.
iFit - They have expanded and now have an app for your TV, iOS device, or android device. You don't have to have an iFit enabled workout machine anymore (but you have to manually adjust it yourself if you don't). But if you have an iFit enabled machine, it will still control speed/incline but you can override either or both. All that to say, it's amazing on my 50" tv, lol! I love the outdoor workouts the most but they're putting out some great studio workouts too. And they are expanding on other genres such as weight lifting, yoga, etc.
You Tube - Caroline Girvan, Penny Barnshaw (Garage Fitness Girl), and Heather Robertson.
Beachbody - I bought early access to 30 Day Breakaway and 9 Week Control Freak.
Coffeyfit - I mostly just preview now, not enough workout time in a day!
Daily Burn - I resubscribed this year when they sent me a 50% off yearly offer.
