We get it: You don’t always want to do crunches or planks or even use gym equipment to work your abs. Luckily, you don’t have to. If you’ve never thought about working your core while standing, you should. It may even be more effective because your core muscles aren’t just the ones you see in the mirror: They wrap all the way around your body—from your “six-pack” abs to your obliques (which hug the sides of your trunk) to the muscles that stabilize and support your spine.
Pick 2 or 3 moves from the list and add them to a cardio or strength routine. Do each move for the designated number of reps or time and do 2 rounds total. The nice thing about abs: It’s hard to overdo them, so feel free to try 2 or 3 moves one day and 2 or 3 different moves the next time you work out.
