Planking is a great way to add strength-building to your exercise routine. Variations exist to help people of all ability levels.
Maintaining a strong core is important for improving stability, balance, athletic performance, and overall function while preventing back injuries.
One of the best ways to strengthen your core is with plank exercises. Many experts now recommend planking rather than crunches or situps, since planks put less strain on your spine and hip flexors.
Plus, a plank can help strengthen your back, glutes, hamstrings, arms, and shoulders at the same time. That’s a lot of gain for just 30 to 60 seconds of your time.
Whether you’re an expert or a beginner, there are many variations of the plank to help you build a strong core.
This article provides 15 plank variations, ordered from easiest to hardest, to strengthen your core.
If you’re new to planks or haven’t done them in a long time, you may want to start with modified versions of the forearm plank. These could help take pressure off your lower back and still give you a great core workout.
Over time, you can progress to the traditional forearm plank.
1. Knee plank

The knee plank is a great way to kickstart your planking journey.
- Lie on your stomach with your forearms on the floor. Be sure your elbows are directly under your shoulders.
- Press your forearms into the floor and raise your torso off the floor while keeping your knees, toes, and elbows touching the floor. Keep your core tight and your neck in a neutral position (avoid looking up or down), and tuck in your pelvis to avoid lifting your hips or dropping them.
- While engaging your glutes, hold this position for 30 seconds, or as long as you can while maintaining proper form.
Pro tip: While it’s not required, you may wish to use a yoga mat if it’s more comfortable for your elbows and knees.
2. Straight-arm knee plank

A step up from the knee plank is the straight-arm knee plank. This requires a bit more arm and core strength, but is easier to perform than a traditional plank.
- Lie on your stomach with your arms bent at your sides, hands directly under your shoulders, and palms flat on the floor.
- Press your hands into the floor to lift your torso and straighten your arms. Keep your knees partially bent and touching the floor. Aim to have your wrists aligned with your shoulders, core tight, and neck in a neutral position (avoid looking up or down).
- Hold this for 30 seconds, or as long as you can while maintaining proper form.
If you can hold a modified plank for 30 to 60 seconds without feeling too fatigued, you should be ready to try a traditional forearm plank, which is slightly more challenging.
3. Forearm plank
If you’re ready to plank without modifications, the forearm plank is a great way to really feel the burn.
- Lie on the floor and place your forearms directly under your shoulders.
- Slowly lift your torso off the floor by pressing into your forearms and knees. Contract your core as you raise up, and maintain a neutral neck and spine.
- Tuck your toes under and lift your knees so that your body forms a straight line.
- Hold this for 20 to 30 seconds, building up to 1 minute or longer. According to Guinness World Records, the longest forearm plank was held for over 9.5 hours!
Pro tip: Let your gaze fall toward your mat, approximately 1 foot in front of you, so your neck is in a neutral position.
4. Straight-arm (full) plank
As you build up your strength, try increasing the difficulty by transitioning to a straight-arm plank, also known as a full plank.
- Start on all fours with your hands directly under your shoulders and your knees slightly behind your hips.
- Push your hands into the floor and raise one knee at a time off the floor. Straighten both legs, so you’re in a straight line from heels to head. Your body should look as if you’re in the upward position of a pushup. Ensure that your hands and shoulders are aligned, legs are strong, feet are hip-width apart, and core is engaged.
- Hold this position for 30 seconds or longer, as long as you can maintain proper form.
Once you’ve mastered the traditional plank, try these variations to activate different core muscles and improve your coordination.
5. Forearm to full plank
You already know how to do a traditional plank, but transitioning between forearm and full plank is a great way to progress your workout.
- Start in the forearm plank position.
- Straighten one arm at a time to lift yourself into the full plank. Try this slowly at first to perfect the transition. Place your hands where your elbows were so that your hands are directly under your shoulders in high plank.
- Return to the forearm plank position by slowly bending one arm and then the other.
- Continue this for 30 seconds for 1 set, performing 2 to 3 sets total. As you progress, pick up the pace according to your comfort level.
Pro-tip: Engage your core to minimize swaying of your hips as you alternate positions.
6. Side plank on forearm
The side plank is a plank variation that largely targets your glutes, obliques (muscles on the sides of your torso), and hip abductors.
- Lie on one side with your legs almost straight and your hips, knees, and feet stacked. Ensure your elbow is directly under your shoulder, with your forearm flat. Lift your other arm straight into the air (or keep it at your side if this is too difficult).
- Push your hand and forearm into the floor to lift your torso. Maintain a tight core and keep your hips lifted, straightening your legs fully. Your body should be close to a straight line.
- Try to hold this position for 20 to 30 seconds, then switch sides.
Pro tip: To make it easier, keep your knees touching the floor while you hold the rest of your body up. To modify with knees on the floor, your knees should be bent with your feet pointed back to avoid putting strain on your knees.
Alternatively, you can increase the difficulty and build greater stability with variations such as straightening your arm or raising and lowering your hips.
7. Walking plank
Walking sideways with your plank can help strengthen your core as well as your upper and lower body muscle groups. These include the deltoids, glutes, quads, hamstrings, and even calves.
- Start in a full plank position with your hands directly under your shoulders. Activate your glutes and abs to prevent injury and gain maximum benefit.
- Begin to shift laterally (to the side) by simultaneously moving your right hand and foot to the right.
- Lift your left hand and foot to meet in the center and return to the plank position.
- Complete 5 steps to the right and then 5 to the left for 1 set. Try to complete 3 to 5 sets, or as many as you can safely perform in 1 minute.
Pro tip: Take your time with this move to ensure proper form and to effectively target your muscles. Be sure to keep your core tight the entire time.
8. Plank with shoulder tap
Planks with shoulder taps can help work overall stability and several muscle groups, including your hip flexors, abs, shoulders, and glutes.
This move adds an extra challenge to the traditional straight-arm plank.
- Start in a traditional straight-arm plank position. Widen your legs for more stability, if needed.
- Keeping your core tight, lift your right hand off the floor and touch your left shoulder. Then, return your right hand to the floor.
- Lift your left hand and touch your right shoulder.
- Continue to alternate hands for 20 to 30 seconds.
Avoid rotating your shoulders or hips during this movement. The goal is to keep your body in a straight line.
Pro tip: If this is too difficult, start on your knees (straight-arm knee plank) or take a wider stance. To increase the difficulty, bring your feet together. This makes it harder to maintain stability.
9. Reverse plank
This full-body exercise targets several muscle groups, including your glutes, hamstrings, shoulders, and chest. Some research suggests that the reverse plank could also help improve a slouching posture.
Instead of facing downward, position yourself with your stomach toward the ceiling.
- Sit tall on the floor with your legs extended in front of you. Place your hands behind you on the floor, with your fingertips pointed toward your feet.
- Engage your glutes, core, and arms to lift your hips, forming a straight line from heels to shoulders. Ensure that your shoulders are drawn down, away from your ears. Avoid dipping your hips by slightly tucking your pelvis.
- Hold this for 20 to 30 seconds, or as long as you can while maintaining proper form.
Pro tip: If you want a greater challenge, add a leg raise: While holding the reverse plank, bend at the hip and lift your right leg up toward the ceiling. Be sure to keep your hips stable and upper body strong while lifting. Return your leg to the floor with control and repeat with the other leg.
To make the reverse plank easier, place your hands on an elevated surface such as a step or bench.
Some more challenging plank exercises may be more dynamic, which can help improve aerobic fitness. Others may include weights to help increase your strength.
Before starting more advanced plank variations, remember that good form is critical for reducing injury and ensuring that your body benefits from the exercise.
10. Spider-Man plank (knee to elbow)
Try these “Spider-Man” planks to feel the burn in your obliques, abs, and lower body.
- Start in full plank position.
- Pull your right knee toward the outside of your right elbow and then push it back to return to a plank position. Make sure your knee is open out to the side, so your inner thigh hovers over the floor as you move your leg.
- Exhale as your knee comes forward and inhale as you push it back.
- Start with 8 to 12 reps on each side. Aim for up to 20 reps on each side as you get stronger.
Pro tip: Take your time. This move is all about proper form and controlled movement. Maintain proper form by keeping your hips elevated, and avoid swaying side to side.
11. Plank with alternating knee to elbow
This is another move that will target your obliques.
- Start in full plank position.
- Lift one leg and pull your knee toward the opposite elbow.
- Push your leg back to the starting plank position. Be sure to keep your abs and glutes tight throughout the exercise.
- Continue alternating sides for 20 to 30 seconds, or as long as you can maintain proper form. Aim for 2 to 3 sets.
Pro tip: Try your best to keep your spine and pelvis neutral, as much as possible.
12. Plank with a row
This is a full-body workout that can help build strength and stability in your upper body, core, and lower body.
- Grab two dumbbells of your choice (if you’re new to working out, start with a light weight to ensure proper form).
- Get into full plank position with each hand gripping a dumbbell.
- With your right arm, lift the dumbbell to the side of your waist or toward your hip to perform 1 row.
- Return the dumbbell to the starting position.
- Perform 1 row with your opposite arm.
- Complete 8 to 12 reps on each side. Aim to do 2 to 3 sets.
Pro tip: Keep your core engaged to perform the dumbbell row with control. If you’re swaying your body to lift the dumbbell, try using a lighter dumbbell.
You can also do this exercise with no weights at all. If your opposite leg lifts off the floor, use a lighter dumbbell and keep your glutes tight.
13. Mountain climber
Mountain climbers activate your whole body. They can be part of an effective core training program to help increase endurance, strength, and stability.
Be sure to keep your wrists, arms, and shoulders stacked throughout the exercise.
- Start in full plank position with your hands directly under your shoulders.
- Place your hands slightly wider than your shoulders and use your upper body and pelvis to stabilize yourself.
- Keeping your core engaged, lift your right foot off the floor and bring your right knee toward your chest. Avoid rotating your hips or shoulders. Return to the starting position and do the same with your left knee.
- Continue this movement for 20 to 30 seconds, or as long as you can maintain proper form.
Pro tip: As you become more comfortable, you can pick up speed. The faster you go, the more cardiovascular benefit you gain — but be sure to still safely maintain proper form.
14. Plank jack
Plank jacks get your heart pumping during your strength routine.
- Start in a forearm plank or high plank.
- Jump both feet outward, wider than hip-distance apart.
- Immediately hop them back into the original plank position.
- Aim to complete 2 to 3 sets of 30 seconds, or as long as you can maintain proper form.
Pro tip: Throughout the exercise, be careful not to raise or lower your hips out of the straight-line position.
15. Swiss ball jackknife
Swiss ball jackknives are also excellent for building strength and stability.
Research shows that using an exercise ball during the plank exercise can better activate your core muscles than simply being on flat ground or a yoga mat.
This is considered a very advanced move and should be done with caution.
- Start in full plank position with your lower legs or feet on an exercise ball. The farther the ball is from your head, the harder the exercise will be. Activate your abs to maintain stability and align your spine.
- Gently lift your hips by engaging your core and pushing through your shoulders. Roll the ball forward with your feet, pulling your knees toward you. Be careful not to drop your hips or round your back.
- Extend your legs, rolling the ball back, to return to the starting plank position. Be sure to keep your shoulders directly over your wrists throughout the exercise.
- Due to the difficulty of this move, you may be able to perform only a few reps at a time. Continue to increase the number of reps as you gain strength.
Pro tip: Moving the ball farther away from your center increases the challenge for your abs. Aim to initiate the move from your lower abs, not your hip flexors.
If you’re new to planks or exercising, aim to hold a plank for 10 to 30 seconds. Remember that maintaining proper form is more important than duration.
This depends on your overall goals and how difficult the plank is for you.
If 1 minute is challenging, then it could help you build strength, stability, and function. If 1 minute is too easy, or you can hold the position for longer, consider trying more advanced variations to better activate the muscles.
Planks themselves don’t burn belly fat. But they might contribute to overall fat loss by burning calories, increasing abdominal strength, and boosting your metabolism.
Planks are an excellent strength workout to add to your fitness routine.
Whether you’re a beginner or an advanced exerciser, there are many plank variations you can try.
With these variations, you can keep challenging yourself and building your stability and strength to help prevent injury and improve your overall health.
If you’re not sure where to begin, consider speaking with a healthcare professional or certified trainer. They can advise you on plank techniques, form, and variations that best meet your individual goals.
