The best workout is the one you have created because it will focus on your goals.
Remember that you can create 3 workouts without be a pro member.
I create 3 different workouts for my whole body. So they are perfect for me.
Squat and lunges for my legs.
Curls fo my arms
Different abs exercice for .... my abs..
Here are the links :
Reach Your Arms Limits
Abs On Fire
So the first thing to know is what is your goal?
Not sure which is my fave, but I've just done "muscle memory" (or at least I think its called that, can't remember ). It's a good all over Dumbell workout that gets your heart pumping as well as your muscles. Plus its quick, 35 mins.
One of the best for me is HITT Me 2
(Yeah they misspelled hi it lol)
I also like Lower Ab Massacre
