That's the husband/wife team, Daniel and Kelly. I believe that are their names.
If you google Fitness Blender their website comes up. I did their first 8 week program and liked it. You can buy it for $7 I think.
All their videos are free, but they just put together their videos into a workout schedule for 8 weeks if you don't feel like planning your own. I'm lazy like that.
Each day has a little quote and motivation tip. It was nicely done. Plus each day was a different workout. I have exercise ADHD so it was great for me. I plan on doing the other two schedules as well at some point.
