Fitting in a muscle-crushing, heart pumping workout in a short amount of time is easy with dumbbell and barbell complexes. In the 10-20 minutes it takes you to complete these short workout routines (including warm-up) you will feel your muscles burning and your lungs gasping for air.
Dumbbell/Barbell Workout Routines
Do each routine without resting between exercises. Aim for 2-3 total rounds, resting between rounds for 60 seconds.
