Use plank pikes to improve core strength and spine stability.
￼HOW TO DO IT
1. Start in a plank position, resting on your elbows directly beneath your shoulders. Aim to make a straight line with your body; keep your back straight at all times.
2. Tighten your core and glutes and drive your hips toward the ceiling as high as possible. Pause for a moment at the apex and then lower yourself back into a plank.
MAKE IT TOUGHER
Press down with your forearms throughout the move to force your abs to work even harder.
Decrease the height you raise your hips if your back rounds during the pike.
