If you had to only do one exercise ever, let it be this.

If you could only pick one exercise, choose the forearm plank, also called a prone bridge. With weight on your forearms and toes and elbows bent about ninety degrees, you train the stabilizers that control your ribs, pelvis, shoulders, and spine. These small muscles are hard to load in normal lifts, yet they decide how well your big prime movers can work. A steady isometric hold builds position, reduces energy leaks, and carries over to lifting, running, and daily tasks. Start with short, high-quality sets and breathe steadily. Keep a straight line from ears to heels, elbows under shoulders, ribs down, hips level. When you own this version, the straight-arm plank is a solid next step. Simple, scalable, joint friendly, and effective.

Lets Clear names first

Forearm plank also called prone bridge

Weight on your forearms and toes, elbows bent about ninety degrees, elbows under the shoulders. This is the version we recommend as your mainstay.

High plank

Weight on your hands and toes, elbows fully extended. Treat this as a progression that is a bit more challenging for the wrists and shoulders.

Glute bridge

Face up, feet on the floor, hips lift. Different exercise and not the subject of this post.

Why choose the forearm plank

Static holds build stabilizers. Stabilizers set your position so your prime movers can produce force without energy leaks. When the small supporting muscles around the trunk, hips, and shoulders are stronger and more enduring, big muscles like quads, hamstrings, and lats work with better leverage and less strain. The forearm plank lets you train this system safely, with simple setup, and with precise control of effort.

Technique checklist

Set your forearms on the floor with elbows stacked under shoulders. Hands relaxed.

Make your neck long and keep the chin slightly tucked. Eyes on the floor.

Press the floor away with the forearms so the shoulder blades widen without shrugging.

Draw the ribs down and keep a light tuck of the pelvis.

Squeeze glutes gently and brace the midsection.

Lift knees and hold a straight line from ears to shoulders to hips to heels.

Breathe through the nose if you can. Slow inhale into the sides of the ribs. Long steady exhale. Keep breathing throughout.

Common errors to avoid

Hips sagging or piking

Elbows drifting ahead of the shoulders

Shrugging toward the ears

Letting the head drop or the chin jut

Holding your breath

How long and how often

Use the forearm plank three to four days each week. Place it in a warm up for neural priming or at the end of a session for trunk endurance.

Regressions if needed

Forearm plank with knees down while keeping the same trunk position

Forearms elevated on a bench or step

Short repeat holds of ten to fifteen seconds with full rest

Progressions when ready

High plank on hands for increased shoulder and wrist demand

One leg forearm plank with hips square

Forearm plank with one arm reach for three to five breaths then switch

RKC style plank short high tension bouts of ten to twenty seconds

Slow controlled shoulder taps from the high plank

What it trains

Anterior core to keep the ribs and pelvis controlled

Deep spinal stabilizers to resist extension and rotation

Glutes and quads to keep the hips level

Serratus and lower traps to set the shoulder blades and unload the neck

Who should be cautious

If you have acute low back pain, shoulder pain with weight bearing, or a recent abdominal surgery, start with a regression or speak with a clinician first.

Bottom line

Call it a forearm plank or a prone bridge. Make this your primary hold. It is simple to learn, easy to scale, and it builds the stabilizing strength and endurance that make every other movement more efficient and more resilient. The high plank is a sound next step once you own the forearm version.
