It sure looks simple. But if you’ve ever done a plank, you know that looks can be deceiving.
When done using the correct form, planks are a challenging exercise, used primarily to strengthen your core. While it’s easy to get into plank position, it takes strength and endurance to pull it off for an extended time period.
"Planks are popular because they work. They really fire up your core, plus your entire back. “Planks really work everything — including muscles in your arms and legs. Planks are also great for posture, and they can help improve your balance."

Once you’ve mastered a basic plank (see below), there are many variations that make the move more interesting. As an added benefit, you can work multiple muscle groups simultaneously.
“Planks are great for overall strength training and even for cardio,” says Evans. “Entire workouts can center around the plank. Adding movement will give you a challenge and make it more fun.”
For example, instead of targeting one muscle at a time, like a bicep curl, you can try an up-down plank or renegade rows (pictured below). These planks will target your shoulders, biceps and triceps, all while firming your core and back. You can customize your workout with countless versions of planks, according to Evans. “As you improve on your planks, you can challenge yourself with stability balls, weights and other variations.”
“If you’ve never planked before, I highly encourage you to talk to a trainer at a gym to make sure your form is correct,” suggests Evans. “Doing a plank incorrectly is not only ineffective, it could also cause an injury. Be particularly careful doing planks if you have back pain or injury.”
Basic plank
Perform with perfect form.
Hold this pose for 20–30 seconds (or one set), and work your way up to a minute or more.
- Start your plank from your elbows or on your hands (as pictured).
- Holding your elbows (or hands) directly under your shoulders, hold your body in a straight line from your heels to the back of your head.
- Avoid dropping or raising your hips, head or shoulders.
- Engage your core by sucking your belly button into your spine.
- Hold this pose (pictured) for 20–30 seconds (or one set), and work your way up to a minute or more.
- Remember to breathe through your plank.
- If you’re just starting out, hold the plank position for just a few seconds at a time. It is better to hold proper form for a short period of time than to hold improper form for longer.

Side plank
Works obliques, back, shoulders and biceps.
Start with 3 sets of 20 seconds for each one, then bump your way up to 1 to 2 minutes each over time.
- Start by lying on one side with your legs stacked on top of one another on your feet.
- Lift your hips and prop your body up on your elbow while keeping your feet stacked.
- Just like a regular plank, your head should be in line with your back, and your body should form a straight line from your shoulders to your ankles.
- Hold this position as recommended, then repeat on the other side.
Up-down planks
Works your back and abdominals, biceps and shoulders.
Start with 3 sets of 20 seconds for each one, then bump your way up to 1 to 2 minutes each over time.
- Start in plank position. While maintaining a strong, flat back, bend one arm down until the forearm is onto the floor.
- Then, do the same with the other arm. Then “walk” your hands back up to a hand plank one arm at a time to get back to the beginning position. That’s one rep.
- Repeat on other side, starting with the other arm.
"Quality is far more important than quantity. Drop to your knees if necessary, instead of balancing on your toes."
