20 Minute Fitness Series - Legs with Weights

This workout is part of our 20 Minute Fitness Series. It's a superset workout for legs, using dumbbells. There are 3 supersets - each superset has 2 exercises in it and will be performed 3 times. The exercises will be performed for 50 seconds with a 10 second transition between exercises, and a 30 second recovery between supersets. I'm using an app called Seconds.
