Total Core Workout #1

"This workout is an effective total core workout to build leaner, more toned abs, especially after turning 40," explains Marissa West, CPT and nutrition specialist, founder of West Kept Secret. "It can be harder to build muscle mass, especially in the core as we age, but this series takes each core muscle group to fatigue while ensuring safe form and protecting the back."

The below total core workout for flatter abs is West's signature ab series. You'll start by performing each exercise for 10 reps, and repeat all by decreasing the rep count by one for every round you're able to do.

1. Crunches

Place your fingers behind your neck—without interlacing them—and lift your head off the ground. Crunch up as you bring your chin toward your chest, then lower back down. Complete 10 reps.

2. Reverse Crunches
