The 15 Best Abs Exercises You Can Do Anywhere and Anytime

Most bodybuilders train their abs at the end of their workouts. This makes a lot of sense because the abs are indirectly involved in almost every exercise you perform. Train your abs first, and you run the risk of weakening the very muscles you use to support your spine during squats, deadlifts, overhead presses, curls, etc.

However, if you train your abs at the end of your workout, you may find that you are a) too tried to train them effectively and b) end up treating them as an afterthought. It takes more than a quick set of crunches to sculpt the perfect six-pack.

After all, the abs are an important muscle group, and if you want to develop them to their fullest, you need to train them correctly. That means working them with plenty of volume and intensity and hitting them from several different angles. Such an approach is time-consuming, which is why training your abs at the end of your workout may not be ideal.

One way around this problem is to stop training your abs at the gym and work on them at home. That way, you’ll have all the time and energy you need to get a great abs workout.

You may be wondering how you’re going to train your abs without gym equipment. After all, what’s better than doing cable crunches, machine crunches, and cable Pallof presses?

The good news is that there are plenty of abs exercises you can do without equipment that are ideal for home workouts.

In this article, we reveal the 15 best abs exercises you can do anywhere and anytime.

Abs Anatomy 101

You don’t need an intimate knowledge of anatomy and physiology to train your abs. That said, knowing just a little about the muscles that make up your midsection can be helpful. For starters, it will make choosing the best exercises for your abs workouts a whole lot easier.

The first thing to understand is that while the word abs is short for rectus abdominis, people often say abs when they actually mean their core. Core is the collective term for all the muscles that make up your midsection.

While the rectus abdominis IS an important muscle, it works with all the other core muscles, and they’re all necessary for appearance and function.

The main muscles that make up your core are:

Rectus abdominis – your abs are responsible for flexing your spine. It can pull your sternum down toward your pelvis or lift your pelvis up toward your sternum. There is no such thing as upper or lower abs, but these two different movements make it feel like there are.

Your abs are also split down the middle by a fibrous band of tissue called the linea alba, which literally means white line. Because of this separation, you can contract one side of your rectus abdominus at a time. Subsequently, your abs are also involved in lateral flexion of your spine. This means they bend you sideways as well as forward.

Internal and external obliques – the obliques are located on either side of your rectus abdominis. In a way, they “frame” your abs. There are two different oblique muscles; the internal and external obliques. The external obliques are the largest of the core muscles, while the internal obliques are smaller and located underneath.

The obliques are responsible for the rotation and lateral flexion of your spine. In other words, they turn and bend your spine from side to side.

Transverse abdominis – this hidden muscle is potentially your most important core muscle. You can’t see it, but you’ll definitely feel it working. Known as TVA for short, your transverse abdominis is a deep abdominal muscle that encircles your abdomen like a weightlifting belt.

When contracted, your TVA compresses your abdominal contents to create intra-abdominal pressure or IAP. IAP stabilizes your spine and pelvis from within.

Bracing activates your TVA. To brace, you pull up your pelvic floor like you were trying to stop the flow of urine, contract (but don’t pull in) your abs like you were about to get punched in the gut and inhale. If you’ve done it right, you should feel your entire midsection solidify and feel strong.

You should brace any time you lift anything heavy and bracing will increase core muscle activation during your abs workout too.

Abs Exercises You Can Do Anywhere and Anytime

Save gym time and get a better core workout by training your abs at home. Here are 15 of the best abs exercises you can do anywhere and anytime!

1. RKC Plank

Forget holding a plank for several minutes at a time – that’s pretty much pointless! Try the ultra-intense Russian Kettlebell Challenge (RKC) plank instead.

With this variation, rather than planking for as long as possible, you tense your muscles as hard as you can, so you exhaust them in 10-20 seconds. This is not just more time-efficient but also builds real-world core strength.

Learn how to do the RKC plank here.

2. Hollow Holds

Hollow holds are a sort-of supine (upward-facing) plank. However, because you need to support your legs and upper body, it’s considerably more challenging. Hollow holds are a gymnastic conditioning exercise that’s also popular with CrossFit.

How to do it:

Lie on your back and extend your arms overhead so your biceps are next to your ears. Straighten your legs and point your toes, knees, and feet pressed together.
Brace your core by drawing your ribs toward your pelvis and flexing your abs. Inhale and draw air down into your abdomen. You should feel your entire midsection solidify and become rigid.
Lift your feet, legs, shoulders, and arms off the floor and press your lower back into the ground. The only point of contact should be your lumbar spine region, which is roughly the lower third of your spine, from the tailbone to the mid-back area. Look down your body to your feet; do not tuck your chin into your chest.
Hold for just a few seconds and then relax, working up to longer holds as you get stronger.

3. Hollow Rocks

If you’ve mastered hollow holds, you are probably ready for hollow rocks. With this variation, you transfer your weight up and down your spine by rocking. This shifts the load to different parts of your core, creating a more challenging, more dynamic exercise.

How to do it:

Lie on your back with your arms above your head, biceps next to your ears, and legs straight. Point your toes and squeeze your legs together.
Brace your abs and push your lower back into the floor. Lift your legs and shoulders/arms a few inches off the floor.
Without changing the angle of your arms or legs, rock gently while maintaining core stability. Remember to breathe; no breath-holding, please!

4. Bear Crawl

The bear crawl is basically a moving plank. Transferring your weight from limb to limb as you move forward increases core engagement while also working your arms and legs. With so many muscles involved, this full-body exercise is also great for building fitness and endurance.

How to do it:

Kneel down on all fours so your hands are directly under your shoulders and your knees are under your hips. Pull your toes up and press the balls of your feet into the floor.
Brace your abs, pull your shoulders down and back, and rotate your elbows inward to engage your lats. Your lower back and neck should be neutral. Lift your knees a few inches off the floor while keeping your hips level with your shoulders.
Without lifting your hips, move your left hand and right foot forward, and then your right hand and left foot.
Continue crawling forward over the specified distance or number of steps.
You can also bear crawl backward, sideways, and diagonally.

5. Walkouts

Walkouts involve moving from standing to an extended plank position for reps. As such, it’s an excellent core and abs exercise that also works your arms, shoulders, and chest. Also, performed with straight legs, walkouts could help improve your hip and hamstring mobility.

How to do it:

Stand with your feet together and your arms by your sides. Brace your abs and pull your shoulders down and back. Bend your knees slightly.
Hinging forward from your hips, place your hands on the floor in front of your feet. Bend your knees as much as necessary to do this.
Keeping your abs tight, walk your hands forward and into the push-up position. Walk your hands a little further forward to make this exercise more challenging.
Walk your hands back toward your feet and then stand up.
That’s one rep – keep going!

6. High Birddog

Birddogs are usually done while kneeling. That’s a decent option for beginners but not usually intense enough for more advanced exercisers. The high birddog is a much more challenging exercise and should provide your abs with a far more intense workout.

How to do it:

Adopt the push-up or high plank position with your arms, legs, and body straight. Brace your core.
Without twisting your shoulders or hips, lift your left hand and right foot so they are roughly parallel to the ground. Hold this position for 3-5 seconds.
Lower your limbs and then repeat on the opposite side.
Continue alternating sides for the duration of your set.
Make this exercise harder by moving your arms forward to extend your base of support.

7. Bench Plank Mountain Climber

The bench plank mountain climber involves moving your legs while stabilizing your core. This increases midsection muscle engagement to produce a more challenging workout. Rest your forearms on a weight training bench or sturdy chair. You can also do this exercise in the high plank position, i.e., with straight arms.

How to do it:

Place your forearms on an exercise bench and walk your feet out and back into the plank position. Brace your abs.
Bend one leg and pull your knee up and into your elbow/the edge of the bench.
Extend your leg, swap sides, and repeat.
Continue alternating legs for the allotted duration.

8. Alternating Leg Lowers

Double leg raises are a popular old-school abs exercise. However, it’s very hard to do them without letting your lower back lift off the floor. The resulting lumbar spine hyperextension a) makes the exercise less effective and b) could result in back injury. Moving one leg at a time is a much safer option and, as an added benefit, increases oblique muscle activation.

How to do it:

Lie on your back with your arms extended straight at your sides.
Brace your abs and lift your legs until your feet are over your hips and your knees are relatively straight.
Keeping your left leg stationary, lower your right leg down until your heel lightly touches the floor. Keep your lower back pressed flat.
Return to the starting position and repeat with your left leg.
Alternate legs for the duration of your set.

9. Side Planks

While regular and RKC planks work your entire core, they primarily emphasize your rectus abdominis. Switching to side planks provides more work for your obliques. As the obliques are every bit as important as your abs for appearance and function, it’s important to include them in your abs workouts.

How to do it:

Lie on your side and rest on your elbow. Your body and legs should be straight. Brace your abs.
Lift your hips up so your shoulders, hips, and feet form a straight line. Tense your entire core as hard as you can.
Hold for as long as possible, then relax and swap sides.
Make this exercise harder by lifting your uppermost leg.

10. Lying Windshield Wipers

Lying windshield wipers are a challenging core exercise that specifically targets your obliques. It’s a great home alternative to things like cable Pallof presses and cable woodchops. Be warned; this exercise is more strenuous than it looks!

How to do it:

Lie on your back with your legs straight and arms extended out to your sides. Brace your core and lift your legs, so they’re vertical.
Using your arms for balance, rotate your hips and lower your legs down to the side until they’re just above the floor and close to your outstretched hand.
Return to the starting position and then repeat to the other side.

11. Side Jackknife

The side jackknife is another excellent bodyweight core and oblique exercise. It’s a very spine-friendly exercise that is ideal for home workouts as all you need to do it is a foam mat or folded towel to lie on.

How to do it:

Lie on your side with your body straight. Your hips and shoulders should be stacked, i.e., vertical, and not leaning forward or back.
Place your uppermost hand on your temple and push your elbow back to open your chest.
Extend your lowermost arm out in front of you for balance.
Contract your obliques, brace your abs, and lift your shoulders off the floor. Simultaneously lift your top leg. Hinge at the waist like a folding jackknife.
Lie back down and repeat.
Do the same number of reps on both sides.

You can also bend your lowermost leg and pull your knee to your elbow (easier) or lift both legs simultaneously (harder).

12. Oblique Crunch

Oblique crunches are a lot like side jackknives. However, you don’t move your legs and must focus solely on lifting your upper body. If you are finding it hard to coordinate moving your legs and upper body simultaneously, you’ll probably appreciate the simplicity of this exercise.

How to do it:

Lie on your left side with your hips square and your legs bent. Place your left hand on the right side of your waist to provide feedback from your working muscles. Put your right hand on the side of your head.
Use your uppermost abs and obliques to flex your torso and draw your right shoulder down toward your hip. Move slowly and deliberately, contracting your obliques as hard as you can.
Pause at the top of each rep for 2-3 seconds, lie back down, and repeat.
Roll over and do the same number of reps on the opposite side.

13. Butt-ups

With no bar to hang from, and no captain’s chair to use, you may be wondering how you’re going to do hanging knee and leg lifts at home. Good news; you can work the same muscles with butt-ups. This might not be the most challenging abs exercise, but if you leave it to the end of your workout when your muscles and tired, it can still be effective.

How to do it:

Lie on your back. Brace your abs and raise your legs, so they are straight and vertical. Press your lower back into the floor. Put your arms on the floor by your sides for balance. Rest your head on the floor to relax your neck.
Without using your arms, lift your butt off the floor and push your feet up toward the ceiling. Try to keep your legs vertical, as moving them toward your head will make this exercise easier.
Without dropping your legs, lower your butt back down to the floor and repeat.
Increase abs engagement by exhaling forcefully as you lift your butt and inhaling as you lower.

14. Flutter Kicks

Flutter kicks are a popular exercise in the military, especially with the Navy SEALs. They involve bracing your abs to stabilize your spine while you move your legs. Done for reps or time, this is a demanding abs exercise you can do anywhere and anytime.

How to do it:

Lie on the floor with your legs straight. Put your hands flat on the floor under your butt. Brace your abs.
Lift your head and shoulders a few inches off the floor and lift your legs by roughly the same amount. Push your lower back into the floor and brace your abs.
Without letting your lower back arch, kick your feet up and down using an alternating leg action. Four kicks equal one rep.

15. Bicycle Crunch

Looking for an exercise that trains your abs and obliques at the same time? Look no further than bicycle crunches. This is a great exercise if you want to work your entire core but don’t have a lot of time to spare.

How to do it:

Lie on your back with your legs straight. Place your hands on your temples, brace your abs, and lift your feet a few inches off the floor. Press your lower back into the floor.
Bend one leg and pull your knee in toward you. Simultaneously, lift your head and shoulders, twist your upper body, and touch your opposite elbow to your bent knee.
Return to the starting position and repeat on the other side.
Continue alternating legs for the duration of your set.
You can also do this exercise with your straight leg resting on the floor, which is considerably easier.

Best Abs Exercises – Wrapping Up

There are hundreds of abs exercises to choose from, but some are better than others. While crunches and sit-ups are okay, they’re not the most exciting exercises, and if you do them too often, they’ll start to lose their potency. Plus, after doing them for a few weeks, you’ll probably be able to crank out a whole lot of reps, and that’s not a good use of your training time.

With 15 alternative exercises to choose from, you have everything you need to train your abs without equipment and in the comfort of your own home.

One of the best ways to make your abs workout both enjoyable and productive is to arrange your chosen exercises into trisets or circuits. Pick 3-5 exercises, and then do them back-to-back to hit your abs from multiple angles and raise the intensity of your workout. Rest a moment, and then repeat a couple more times to work your abs thoroughly in ten minutes or less.

Finally, remember that if you want to see your abs, you may need to drop some fat and get ripped. After all, it doesn’t matter how sculpted your abs are; if they’re covered in a layer of fat, they’ll be invisible!
