20-Minute Core Workout

The Plank

The basic core workout begins with the plank, a move that actively engages all major core muscles.

To enter the pose, prop your upper body on your forearms and lower body on your toes. Keep your knees rigid and your abdominal muscles taut. Do not let your hips drop or your upper back sink between your shoulder blades.

Per the exercise's name, your body should be as stiff and straight as a plank. Hold the position for 15 to 60 seconds while inhaling and exhaling slowly. Do not pant or hold your breath.

Extend one arm in front of you for 10 seconds to increase the intensity, and repeat on the other side. You can do the same with each leg. With each arm or leg extension, focus on engaging the diaphragm muscles, abdominals, hips, and lower back. 

Side Plank

The side plank is a core workout that engages the lateral stabilizers that run from the ankle to the shoulder. The exercise increases lateral hip strength and stability and helps keep the obliques strong.

To enter the pose, start in the plank position. As you shift your weight to one arm, position your upper foot behind your lower foot to stabilize the body. Once stabilized, you can place your feet together. Do not allow your hips to sag. 

To challenge yourself, extend your upper arm toward the ceiling, holding the position for 15 to 60 seconds while maintaining complete control of your core. Repeat on the opposite side.

Lift the upper leg a few inches and hold it for 10 seconds to increase the intensity. Repeat on the other side.

V-Sit Pose

The V-sit is an effective abdominal exercise that works the rectus abdominis, external obliques, and internal obliques while also engaging the hip flexors.

To do the V-sit, take a seated position on the floor. As you inhale slowly, contract your abdominal muscles while lifting your legs to a 45-degree angle. Reach forward to stabilize yourself or place your hands by your sides if you feel less stable.

Hold the pose for 15 to 60 seconds. Relax for 15 to 20 seconds and repeat two more times. As you get stronger, increase the duration of the pose.

Bicycle Crunch

The bicycle crunch is a classic core workout that works nearly all of your core muscles simultaneously, especially the rectus abdominus and obliques.

To perform the exercise, lay flat on the floor with your lower back pressed to the ground. Rest your hands behind your head without yanking your neck. Bring one knee up to a 45-degree angle and keep the other straight.

You will then shift your legs back and forth as if peddling a bike, alternately extending one knee while lifting the other. As you do, touch your left elbow to your right knee and your right elbow to your left knee—complete 10 to 25 reps on each side, keeping your movements deliberate and steady. Relax and complete two more sets.

As you build strength, increase the number of reps per set.

The Bridge

The bridge exercise isolates the hamstrings, lower back, and gluteus muscles (buttocks). It is also an essential rehab exercise to improve core strength and spine stability.

Start flat on your back with your knees bent, feet flat, and arms positioned by your sides to enter the pose. As you inhale slowly, tighten your ab and gluteus muscles while lifting your hips to create a straight line between the knees and shoulders. Hold the pose for 15 to 60 seconds without dropping the lower back or buttocks. 

To increase the intensity, lift one leg as high as possible and hold it for 10 seconds. Repeat on the other side. As you build strength, increase the duration of the pose.

Push-Up Lat Row

The push-up lat row is an advanced core exercise that combines a push-up with a dumbbell row. Not only does the added weight increase the intensity of the upper body workout, but it also activates both the core stabilizers and latissimus dorsi muscles of the middle back.

Start in a push-up position with each hand on a dumbbell. Alternately from one hand to the next, lift the weight as you inhale and lower it as you exhale. If you are dropping the weight, change to a lighter weight that you can control from the first rep to the last.

During the movement, keep your abdominals taut and your lower back straight. Do not let your hips drop or sway—complete 10 reps on each side. Rest and complete two more sets. As you get stronger, you can increase the weight of the dumbbells.

Skip With a Twist

The skip with a twist is a core workout that aims to engage the muscles that rotate the hips, torso, and spine.

Find a level area with enough room to take 10 full leaping strides. Start by skipping forward 10 paces (five per side), swinging your arms freely from side to side. As you move, you would twist your upper torso to the right as your right knee rises, and move your upper torso to the left as your left knee goes up.

Focus on keeping your core muscles taut but not rigid. Continue until your body is fully warmed up, and your joints feel loose and relaxed.
