HIIT vs. Bootcamp Workouts: What's the Difference?

When it comes to bodyweight exercises, the abdominal muscles are often targeted for training. You don’t need sophisticated equipment to train the abs; bodyweight movements alone can build muscle and strength. However, just like with other muscle groups, specific workouts may stimulate the muscles better than others. In a study comparing 13 common abdominal exercises1, the American Council on Exercise (ACE) identified three ab workouts that stood out from the rest: bicycle crunches, captain’s chair crunches, and crunches performed on an exercise ball. These three core workouts targeted muscle stimulation in the rectus abdominis and obliques. These core exercises should not only strengthen your abdominal muscles, but they should benefit you in other ways too. Strong abdominals2 are crucial for injury prevention, good posture, athletic performance, and staving off lower back pain. Our top 10 picks for ab exercises To try and maximize your ab workout, knowing which muscles make up the abs3 is useful. While some exercises primarily stimulate the rectus abdominis (the front ab muscles), others call the obliques (internal and external) or the transverse abdominis into action. The external obliques are the muscles located on the sides of the rectus abdominis around the waist, whereas the internal obliques are positioned just below the rectus abdominis. The transverse abdominis is an internal stabilizer located on the lateral sides of the abdominal wall. Next time you want to train your abs, incorporate the first three core exercises mentioned below into your workout regimen. The only piece of equipment you’ll need is an exercise ball, which you can find at retail or specialty sports stores. You’ll leverage the power of bodyweight to help build your abdominals! Let’s walk through each of these movements step by step. 1. Bicycle crunches Since this ab exercise utilizes all of your abdominal muscles, ACE highlighted that bicycle crunches are fundamental for ab training. They help stimulate your abdominal muscles so you feel that burn and help improve your fitness. Lie down flat on your back. You can use a yoga mat for comfort during this exercise.Bring your knees to your chest and lift your shoulder blades off the floor.Straighten the left leg and simultaneously turn your upper body to the left. During this movement, bring your right elbow to the left knee. Breathe out as you turn your body.Repeat the process for the other side. 2. Captain’s chair crunches This core exercise4 requires a captain’s chair, a seatless chair with a back and armrests. Don’t be surprised when your obliques feel taxed after these crunches! Press your back against the backrest with your feet on the bottom supports and arms resting on the upper supports.Gripping the handles, lift your feet off the supports and allow your legs to hang straight down.Slowly breathe out as you lift your knees to your chest.Hold the lifted position for a few seconds, then slowly lower the legs back down into the starting position and repeat. 3. Exercise ball crunches Ranked the third most effective abdominal workout5, crunches performed on an exercise ball do a much better job of engaging your core than floor crunches. This exercise targets the abdominals and oblique muscles precisely. Lie back on an exercise ball with your hands behind your head or across your chest. Ensure your feet are stable on the floor.Lean your upper body back on the ball, then use your core to raise yourself forward (just as you would in a traditional crunch). Hold the crunch position for a few seconds, and then slowly lower yourself back down. Other effective ab exercises While the above ab exercises are highlighted by ACE, many others effectively engage your core! When paired with bicycle crunches, captain’s chair crunches, or exercise ball crunches, the following core exercises can offer the variety you need to keep your ab training interesting. 4. V-ups As a total-body movement, V-ups are incredibly powerful and challenging to master! In this core bodyweight exercise, you’re creating a “V” with your upper body and legs, engaging your core during the process. Lie on the floor with your legs extended straight out and your arms by your sides.Lift your legs, arms, and upper body up to where you’re balancing on your glutes. This position should resemble a “V.” Only your glutes should be on the floor.Reach your arms so that they’re parallel to your legs.Hold this position for 30–60 seconds.Lower back down and repeat. 5. Deadbugs Great for all of your abdominal muscles, deadbugs are a functional warmup for lower body workouts, but may also be incorporated as part of your core workout. The key to this movement is to keep your lower back flat on the floor. Lie down flat on your back. You can use a yoga mat for comfort during this exercise.Extend your arms straight up and bring the knees up toward your chest to create a 90-degree angle. Press your lower back into the floor. Focus on keeping it down without allowing it to buckle.Slowly extend your right leg out straight and your left arm overhead. Your heel and hand should almost touch the floor.Hold this position for a few seconds and then return to the starting position. Repeat this process with your left leg and right arm. 6. Planks A plank is a bread-and-butter movement for abs workouts. With bodyweight alone, planks6 are challenging, even to the most advanced fitness enthusiasts. Position yourself on your hands and knees. You can use a yoga mat for comfort during this exercise.Place your hands shoulder-width apart, directly under your shoulders. Your feet should be a bit wider than your hips but you can bring them closer together for a greater challenge.During the plank, keep your body straight, from your heels to your head. Look down at the floor to keep your spine neutral. Engage your core, quads, and glutes. Hold the plank position for however long feels comfortable. For example, beginners can aim for 10 seconds and increase the duration with practice. Do not let your hips or shoulders dip.Come out of the plank position and rest before trying again. 7. Side planks Side planks7 are a great addition to traditional planks, as they help strengthen the shoulders, hips, and obliques. Since you’re on your side in this core exercise, the obliques are doing some heavy lifting here. Lie on your side with your left forearm flat on the floor. Your elbow or hand should be under your shoulder and your legs extended. Your body should be in a straight line.Stagger your feet and engage your core. If this is too difficult, you can instead be positioned on the side of your knees.Slowly lift your hips off the floor and hold the position. You can extend your right arm or keep it immobile.Hold the plank for however long feels comfortable, then lower back down. Repeat this movement on the other side. 8. Heel taps If you’re looking for core exercises that integrate your hip flexors, heel taps are a worthwhile addition to your ab routine. Once you get going with these, you’ll feel your obliques working hard! Lie down flat on your back. You can use a yoga mat for comfort during this exercise.Position your feet on the ground, heels close to your glutes.Engage your core, then lift your shoulder blades off the floor.Reach down to touch your left heel with your left hand and vice versa. 9. Reverse crunches If you don’t have access to a captain’s chair, reverse crunches provide a similar movement. Instead of hanging, you’ll lie on your back without placing strain on your back or neck. Lie down flat on your back. You can use a yoga mat for comfort during this exercise.Lift your legs so that your knees are slightly bent.Press your lower back into the floor and place your hands at your sides.Slowly bring your knees up towards your chest. This will lift your hips off the floor. Keep the lower back pressed down.With control, lower your legs back down, but not all the way to the floor. 10. Hollow holds When performed correctly, hollow holds will strengthen your abs. The contraction of your ab muscles is part of what powers this movement, so it’s important to first nail the form down on these, as is the case with the other exercises. Lie down flat on your back. You can use a yoga mat for comfort during this exercise.Press your lower back firmly into the floor.With the hands placed at your sides, raise your legs about one to two inches off the floor. Ensure the lower back does not buckle.Lift your shoulder blades one inch off the floor. Again, keep the lower back pressed firmly into the floor.Hold this position for a few seconds and then relax.

When you hear “strength workouts,” your mind may conjure images of dumbbells or weight machines. For “cardio workouts,” you’ll likely think of walking, running, hiking, or even sprinting. Just like you don’t need weights to build strength, you don’t need to become a runner to work on your cardiovascular health1. Cardio classes can take on a whole new meaning with bodyweight workouts! Bodyweight exercise is another way to try to become more physically fit and hit those daily cardio goals. Traditional avenues of cardio exercise may not always be what you’re in the mood for. Fortunately, you can harness the underrated power of bodyweight exercises2 to ramp up your heart rate and get your sweat on anytime, anywhere (even in your living room!). With regular bodyweight training3, you may notice a difference in your endurance, metabolism, and general fitness ability. In a recent study4, researchers found that after four weeks of whole-body aerobic-resistance training, participants demonstrated improved cardiovascular fitness. This was in opposition to the other control groups, one that solely performed treadmill exercise and another that engaged in no exercise. Using your weight as resistance is one of the easiest, most convenient ways to get fit. There are many different types of bodyweight exercises to choose from for your next workout, some of which you may find are better for cardio than others. Below are 10 cardio bodyweight exercises to try the next time you’re ready to work on your endurance! Since they only require your bodyweight, you can create a workout to do right in your home gym. Note that these exercises can be challenging, but don’t worry—we’ve included modifications to accommodate any fitness level. 1. Skaters With this side-to-side bodyweight exercise, skaters allow you to work on your balance and agility. Stand with your feet hip-width apart. Knees should be slightly bent.Jump to the right with your right foot. Sweep the left foot behind your right leg. Tap your right foot with your left hand.Alternate sides by jumping to the left with your left foot while the right foot sweeps behind you. Tap your left foot with your right hand.Use your arms to help keep the momentum. Note: Instead of distributing your weight on the foot, land lightly on the ball of your foot and quickly alternate to the left. Modification Instead of lateral jumps, you can also perform skaters by taking lateral steps. 2. Jumping jacks A timeless, full body exercise! It’s easy to get into the rhythm of jumping jacks, which makes them a worthwhile exercise to add to any workout routine. Stand with your feet shoulder-width apart and arms by your sides.Jump with your feet out to your sides and your arms overhead. Your body should resemble an “X.” Return to the starting position. Modification To make jumping jacks easier, replace the jump with alternating left and right steps. 3. Woodchops Work your core with no sit-ups necessary! Woodchops are one of those cardio exercises that target your obliques and help strengthen your abdominals. Start with your hands together towards your right side. Hold them about eye-level so your arms are bent at the elbows.Put your weight on your right foot with the left foot slightly raised.As if you were holding an axe, chop your arm across your body with bent knees. Transition your weight from your right to left foot, slightly raising your right foot at the end of the exercise. You should be in a slight lunge position.Bring your arms back to the starting position.Repeat for your left side. 4. High knees High knees are a bodyweight workout that challenges your quads, hamstrings, glutes, calves, and abdominal muscles. Stand with your feet shoulder-width apart.Begin to run in place, lifting your knees to waist level. Make sure you engage your abs during this exercise. Watch your posture—don’t slouch!You can hold your arms out and use your hands as a measure of knee height. Modification Instead of hopping from one foot to the other, perform high knees at a slower pace. Bring one knee up, pause, and then bring the leg back down. Repeat this for the other side. 5. Mountain climbers Testing your stability, mountain climbers simultaneously work your shoulders, arms, core, and legs. These can be taxing for beginners, so take the time to nail down the form. Begin on your hands and knees. Position yourself in a high plank position with your core engaged. Make sure your lower back is not bowed.Bring your right foot up towards your right hand until you reach a lunge position.Quickly jump and switch your feet, so that the left foot is now in front.Continue this alternating pattern. Modification You can modify this bodyweight exercise by slowing it down without jumping. Instead of the quick bursts to transition your feet, you can simply start with the right foot and then bring it back down to alternate to the left foot. 6. Burpees The burpee is a bodyweight workout that is both loved and hated. They are highly effective and offer an intense cardio workout all on their own! Get into a squat position with your knees bent and back straight. Your feet should be shoulder-width apart.Lower your hands to the floor in front of you, so they’re just inside your feet. With your weight in your hands, jump and kick your feet back. You will be in a plank position. Do one push-up, and then perform another jump moving your feet back to their starting position. Stand and jump into the air with your arms outstretched over your head. Land where you began.Come back to a starting position.Repeat. Modification If burpees are a little too advanced, that’s okay! You can bring the difficulty of this exercise down with up-downs. These will help build your strength up so you can easily move through a set of burpees in the future. Get into a squat position with your knees bent and back straight. Your feet should be shoulder-width apart.Lower your hands onto the floor in front of you, so they’re just inside your feet. With your weight on your hands, walk your feet back, so you’re in a plank position. Hold the plank position.Jump to move your feet back to their starting position. Stand and stretch your arms overhead. Come back to a starting position.Repeat. 7. Squat jumps This variation of a classic bodyweight squat calls the leg muscles into action in a big way. A few sets of these will give you that feel-good muscle burn. Position your feet shoulder-width apart.Perform a squat with your arms bent and hands together in prayer position.Rise up into a jump with your legs fully extended. Pushing your arms down during the jump will help get you going.Land lightly and immediately transition into another squat. Do not land with your knees locked, but instead slightly bent to absorb the jump. Modification Are squat jumps feeling too challenging? Perfect regular squats first! Ensure your feet are stable with your back straight and head neutral. You can also perform squat reaches, which are regular squats that require you to bring your arms overhead and hold the squat position. 8. Up-down planks Add more of a challenge to the classic plank by lowering yourself onto your forearms with up-down planks. Get into a plank position on your hands and toes. Engage your core.Lower your left elbow to the floor and then the right. You should be on your elbows.Bring yourself back up to a full plank position by straightening your arms and putting weight back onto your palms. During this exercise, keep your lower back straight.Alternate sides from left to right and vice versa during these planks. Note: If you encounter wrist pain, think about gripping your mat with your fingers. This will create a hollow space between the floor and your palms, which may help ease discomfort. Modification Perform up-down planks starting on your knees instead of a full plank. Make sure your body stays in a line without dipping your lower back. Do not hinge at the waist for this exercise. 9. Lateral bunny hops Bunny hops are an easy way to keep your heart rate up during bodyweight workouts. Start with your feet together.Pretend there is an invisible line at your side.Using your arms for momentum, quickly jump side to side over the line. Keep your legs close together during this exercise. 10. Split lunge jumps Upgrade your classic lunges with explosive jumps! Split lunge jumps are all about power and form with focus on the leg muscles. Stand with your feet together with soft knees.Get into a lunge position first and then continue with a jump. Land in an opposite lunge (if you began with the right foot forward, land with the left foot forward).Quickly jump back up and into the starting position with your feet together.Repeat on the other side.
