Montenegro Method Endurance. It's all body weight, but tough. There are no typical back excercises, though. It's all legs, squat thrusts, planks, and pushups.
Tracie's Power Up (though I will add back work)
Premixes:
Amy's Slow Mo Total Body Premix - 45 min. (I know you wanted <40, but it's not too much longer) : )
Cathe High Step Training Upper & Lower Premix - 38 min.
Jessica Smith Ultimate Bootcamp upper, lower, and total body together - 30 min.
