When it comes to quick and efficient workouts, nothing is as easy as abs. You can do them anywhere and don't need a lick of equipment. Here are two moves you can pair as a superset; do the straight-leg crunch for 15-20 reps, then immediately go into 20 reps of bicycles. Rest 30 seconds between supersets, and aim to do 3-5 supersets total.
