8 min read

Last updated November 9, 2026

The plank looks simple. You hold still and keep your body straight. Yet it ranks among the best exercises for building a strong core, and it needs no equipment at all.

This guide shows you how to plank with good form, how long to hold and how to progress. It also covers common mistakes, easier versions and a four-week plan.

Health note. This article is general fitness information. If you have back, shoulder or wrist pain, are pregnant or recently had surgery, check with a health professional before you start.

Key Takeaways

A plank works your abs, back, glutes, shoulders and legs at the same time.
Keep a straight line from your head to your heels.
Beginners can start with holds of 10 to 30 seconds.
Good form matters far more than hold time.
Stop if you feel pain rather than normal muscle fatigue.

Why Planks Are Worth Doing

Your core includes far more than your six-pack muscles. It covers the deep belly muscles, the muscles along your spine, your hips and your glutes. Together they keep your spine steady when you move.

Banner Health shared plank advice from its sports medicine team. Michela McGertt, a clinical athletic training student with Banner Sports Medicine, explains the payoff. A strong core supports the spine and almost every movement you make.

Builds core strength without any equipment
Supports better posture at a desk or on your feet
Improves balance and stability
Works the shoulders, chest, arms, glutes and legs as well
Helps with everyday tasks like carrying groceries or standing on one foot

Because you do not bend your spine, planks are often gentler on the back than crunches. That makes them a popular choice for beginners.

How to Do a Forearm Plank

The forearm plank is the classic version. Follow these steps slowly the first few times.

Lie face down on a mat or carpet.
Place your elbows directly under your shoulders, with forearms flat on the floor.
Tuck your toes under and lift your body onto your forearms and toes.
Make a straight line from your head to your heels.
Pull your belly button toward your spine to brace your core.
Squeeze your glutes to protect your lower back.
Keep your neck neutral by looking at the floor just ahead of your hands.
Breathe slowly and steadily for the whole hold.

Lower your knees to the floor to finish. Rest briefly, then repeat.

A quick form check

Ask a friend to look at you from the side, or film yourself with your phone. Your back should look flat, like a tabletop. Your hips should sit level with your shoulders.

10-30Seconds per hold is a sensible starting point for beginners.

How Long Should You Hold a Plank?

According to the Banner Health guide, beginners can start with 10 to 30 seconds per round. McGertt stresses a simple rule.

“A shorter plank with good form is better than a longer plank with sloppy form.”

Once your form starts to slip, stop and rest. Holding a sagging plank for longer only strains your back.

Level	Hold time	Rounds
Beginner	10 to 30 seconds	2 to 3
Intermediate	30 to 60 seconds	3
Advanced	60 to 90 seconds	3 to 4

You do not need marathon holds. Several shorter rounds with perfect form build strength well. Many trainers prefer harder variations over very long holds.

Common Plank Mistakes

Mistake	What happens	How to fix it
Hips sagging	Strains the lower back	Squeeze your glutes and brace your belly
Hips too high	Takes work away from the core	Lower your hips until your body is flat
Holding your breath	Raises tension and cuts the hold short	Breathe slowly in and out
Looking forward	Strains the neck	Look at the floor just ahead of your hands
Shoulders behind elbows	Stresses the shoulders	Stack shoulders over elbows

Shaking is normal, especially near the end. Sharp or pinching pain is not, so stop if you feel it.

Easier Plank Versions

If a full plank feels too hard, start with one of these. Each still trains your core.

Wall plank

Stand facing a wall and place your forearms on it at shoulder height. Step your feet back until your body forms a slanted straight line.

Knee plank

Get into a forearm plank but keep your knees on the floor. Keep a straight line from your head to your knees.

High plank

Hold the top of a push-up with your hands under your shoulders. Some people find this easier than the forearm version. Others find it harder on the wrists.

Incline plank

Rest your forearms on a sturdy bench, couch or step. The higher the surface, the easier the plank.

Harder Plank Versions

Once you can hold a forearm plank for 60 seconds with good form, try a harder version.

Side plank. Balance on one forearm and the side of one foot to work the side of your core.
Shoulder taps. From a high plank, tap each shoulder with the opposite hand without rocking your hips.
Leg lifts. Lift one foot a few inches, hold, then switch.
Plank to push-up. Move from forearms to hands and back again.
Plank jacks. Jump your feet out and in like a jumping jack.

Add one new variation at a time. Practice each one for a full week before you add another. Keep the same focus on a flat back and steady breathing.

Four-Week Plank Plan

Do this plan three days a week, with a rest day between sessions. Rest 30 to 60 seconds between rounds.

Week	What to do
Week 1	3 rounds of 15 to 20 seconds, knee or forearm plank
Week 2	3 rounds of 25 to 30 seconds, forearm plank
Week 3	3 rounds of 35 to 45 seconds, plus one side plank of 15 seconds on each side
Week 4	3 rounds of 45 to 60 seconds, plus one side plank of 20 seconds on each side

If a week feels too hard, repeat it. Progress at your own pace.

Pair planks with other moves

Planks fit neatly into a short home workout. Try squats, push-ups and glute bridges, then finish with a plank.

Safety Tips

The Banner Health guide suggests extra care for some people. Talk to a health professional first if any of these apply.

A history of shoulder, wrist or lower back pain
Disk problems or arthritis
Recent surgery
Pregnancy or the months after giving birth

Stop or switch to an easier version if you feel pain. Normal muscle tiredness and shaking are fine.

Use a mat or folded towel under your forearms for comfort. A soft surface also helps if your knees touch the floor.

How Planks Fit Into Your Week

Planks build strength, but they are only one piece of fitness. Aim for a mix of cardio, strength and stretching.

Walking is an easy way to add cardio on rest days. Our guide on how to start walking for fitness shows you how to begin.

Most adults benefit from strength work for all major muscle groups at least twice a week. Planks make a good finisher for those sessions.

How to Breathe During a Plank

Many beginners hold their breath without noticing. That raises tension and makes you give up sooner.

Breathe in through your nose for a slow count of three. Then breathe out through your mouth for a count of three. Keep your belly braced the whole time, as if someone might poke it.

If you cannot breathe steadily, the hold is too hard. Switch to an easier version until your breathing stays calm.

Planks for Older Adults

Planks can help older adults keep the core strength they need for balance. A strong core may make it easier to get up from a chair or recover from a stumble.

Start with a wall plank or an incline plank on a sturdy counter. These versions put less load on the shoulders and wrists.

Move to the floor only when the easier versions feel steady. Keep a chair nearby to help you get up and down safely.

Track Your Progress

A simple log keeps you motivated. Write down the date, the version you did and how long you held it with good form.

Use the stopwatch on your phone for each round.
Note how your form felt, such as steady or shaky.
Test your best hold once every two weeks.
Celebrate small wins, like five extra seconds.

Over a month, those small gains add up. Most people notice better posture and an easier time with daily tasks.

Plank Myths

Myth	Fact
Longer holds always mean better results	Good form and harder variations matter more.
Planks burn belly fat	You cannot burn fat from one spot. Overall habits matter.
Planks only work the abs	They work the shoulders, back, glutes and legs too.
You need to plank every day	Two to four sessions a week are plenty.
