The No-Crunch Abs Workout for a Tabata-Style Burn

How it works: Grab some space and a mat (if the floor you’re on is hard) and get to work. You’ll do each move for 20 seconds, as many reps as possible (AMRAP). Then rest for 10 seconds and move on to the next one. Complete the circuit two to four times for a total-body workout with extra focus on your core.
