No frills, easy to follow, educated trainers. I've been using this since college. The membership is like ~$12/month, gives you access to unlimited weekly or monthly programs + membership only workouts. But you can also watch single workouts for free. I typically am doing a monthly program because it tells me what I have to do every day, and I love not having to think about it. I set up my dumbbells in the corner at the gym and follow this on mute. Very trusty!!! They just simply walk you through the workout with correct form. Tasha in my favorite (pictured).
