I Started Doing 6 Minutes of Ab Exercises Every Day, and I Feel Stronger After Just 1 Week

The first exercise is simply holding a plank for 60 seconds. I usually do an elbow plank, but if it's more comfortable, you can also hold a plank in push-up position with your arms extended straight underneath your shoulders. Either way, make sure your back is flat.

• Start on the floor, resting on your forearms and knees.
• Step your feet out one at a time, coming into a plank position.
• Contract your abs to prevent your booty from sticking up or sinking. Your spine should be parallel to the floor, with your abs pulling toward the ceiling.
• Hold for 60 seconds.
