Plank

Reviewed by Bryan Cortez, MS

Brace, don't sag — once 60 seconds is easy, add load, not minutes.

How to do it

Setup

  • Forearms under the shoulders, body in a straight line, glutes and abs braced.

Execution

  • Hold a rigid line, ribs down and pelvis tucked (no sagging), breathe; the quality of the brace beats the duration.

Common Errors

  • Hips sagging (the lower back takes the load)
  • Hips piked up too high
  • Holding the breath
  • Chasing minutes instead of bracing hard

No-Fly Zone

multi-minute holds (add load/leverage instead of chasing time)

The Evidence

Builds anti-extension core stability and bracing. Does NOT build ab size like loaded flexion — pair with cable crunches.

What about supplements?

Train hard and hit your protein first — that's most of it. If the fundamentals are handled, two are worth it for building muscle:

Creatine

Monohydrate, 5 g/day. The most studied muscle supplement.
