Plank

check_circleBenefits

• check_circleStrengthens the deep abs with no movement or added weight
• check_circleImproves posture by working the entire abdominal wall
• check_circleCan be done anywhere and easily progressed by duration
• check_circleBuilds core muscular endurance that supports good posture throughout the day
• check_circleWorks the glutes and shoulders together with the abs, useful for whole-body stability

lightbulbExecution tips

• lightbulbAlign ears, shoulders, hips and ankles in one straight line
• lightbulbPlace the elbows directly under the shoulders and squeeze the glutes
• lightbulbSlightly tuck the pelvis to keep the lower back neutral
• lightbulbBreathe calmly rather than holding your breath
• lightbulbFix your eyes on a spot on the floor about a metre ahead to keep your neck in line with your spine

warningCommon mistakes

• warningLetting the hips sag and the lower back arch
• warningPiking the hips too high to make the hold easier
• warningLetting the head drop or looking too far forward
• warningHolding too long at the cost of perfect alignment
• warningLocking the knees fully straight instead of keeping the legs actively engaged

tuneVariations and alternatives

• tuneHigh plank — straight arms instead of forearms, works the shoulders more and stabilises the trunk differently.
• tunePlank with arm or leg lift — alternately lifting an arm or a leg sharply increases instability and anti-rotation demand.
• tuneRKC plank — maximum contraction of every trunk and glute muscle for only a few seconds, far more intense than a long, relaxed hold.
• tuneWeighted plank — a plate placed on the upper back adds load once form is perfect without any weight.

person_checkWho it's for and level

The plank suits every level, from complete beginner to advanced lifter, because its difficulty is adjusted purely through duration and variation, never through mandatory external load. It's often the very first core exercise taught in gyms or rehab settings, since it teaches pelvic control without joint risk. Runners, combat athletes and team-sport players use it to stabilise the trunk before explosive movements. People returning to training after a long break or lower back pain find it a safe starting point, as long as duration is progressed gradually.

shieldSafety and precautions

The plank is generally safe, but a few precautions matter. With acute low back pain, a recent disc herniation or wrist pain, favour a forearm plank and limit duration, or skip the exercise entirely during a painful flare-up and check with a healthcare professional. Pregnant women, especially past the first trimester, should adapt or avoid prolonged prone positions and prefer standing or side-lying alternatives instead. Stop immediately if you feel sharp low back pain, excessive pressure in the abdomen, or numbness in the hands, a sign of poor weight distribution through the arms.

calendar_monthWhere to place it in your program

The plank works well at the end of a session as a core finisher, or as a light warm-up to switch on the stabilisers before a strength workout. For a beginner, 3 sets of 20 to 30 seconds with perfect alignment is plenty; a more advanced lifter can push to 45-60 seconds or move to a harder variation rather than endlessly extending the hold. Two to four sessions a week, spaced with at least a day of core rest, allow steady progress without overuse. Pair it with a dynamic ab movement (crunch, leg raise) for well-rounded core training.
