I think Fitness Blender is great, and they have workouts that range anywhere from 5 minutes to a hour- so they have a wide variety of workouts that can keep you not-bored!

Do you love the original, structured versions of Zumba and Strong Zumba? POPSUGAR Fitness is a great place to go for it. They also really interesting range of workouts that incorporates Dance, Zumba, Boxing Fitness, toning workouts, etc. I like them a lot!
If you want a 100% fun, sassy, absolutely energetic dance/Zumba workout that burns calories when you are just dancing away with Ashley's irrepressible stamina, energy, and zeal- go here! This is my absolute favourite. Discovering Fit Body by Ashley was the best thing that happened on the workout-side during this lockdown. The vibe is just so, so very good, and her smile and energy is so infectious that you see yourself smiling all the way through her sassy workouts!
You have to try these three- I absolutely love them. And, when you keep alternating between workouts, you feel much better and more enthusiastic about it, which is important to keep it going! Try them, and have fun!
