I follow WayofGray on Instagram, and she is an incredible and positive source of inspiration. I highly recommend following her. Her ebooks have been incredible as well - and for only $10. Easily the best $10 I have ever spent. The workouts focus on high intensity interval training, and they are so good - you really get an amazing workout.

This video channel is a gold mine for someone looking to, well, tone up. These girls know what they are talking about, and they have so many free, fun videos. They tend to focus on specific body parts and strength training.
