The prone plank is a classic core stability drill that gets no love.  The mainstream has moved on the to the fancy stuff and skipped the essentials.  Planks have low entertainment value and high reward.  They are easily progressed for an increased challenge, but the picture above is “ground zero”.  The abdominals are stabilizers first and foremost.  Train them for success now that you know that.

Use these tips for execution…

• Pressurize your torso musculature as if you were going to take a right hook.
• Breathe against your now pressurized stomach.
• Straight posture from shoulders to heels.  You’re a pillar.
• Put your mind somewhere else and dig in.
