11 Core-Stability Exercises That Do More For Your Abs Than Crunches Ever Could

Kira Stokes, a NASM-certified trainer and creator of the Kira Stokes Fit app, recommends doing planks to improve your core strength and stability.

• Start on your hands and knees on the floor. Lower onto your forearms, with your elbows directly under your shoulders.
• Extend your legs to place your toes on the floor behind you, and lift your knees off the ground so you're holding your body up with your forearms and toes.
• Hold this position, trying to keep your back flat and core engaged. Don't let your hips drop or lift up, and think about keeping your neck long and in line with your spine.
• Try holding this position for 10 seconds, and work your way up to a minute or longer. Do two or three sets.
