If you have Cathe On Demand, you could use the ICE series and its' Muscle Meltdowns that clock in around 15-20 min. for each weighted body part. (You would need to add on her w/u beforehand, though, as these are just the 15 min. weight workouts without a w/u or c/d).
In her ICE User's Guide, she has rotations that include them...just ignore the main workout, core work, and blizzard blasts and follow just the Muscle Meltdowns as noted. As you get stronger and your endurance improves, you could add on the main workout, the blizzard blast, ab work, etc.
