Your abdominal muscles are like any other muscle in your body — you need to work them correctly when you work out, and you need to fuel them well.
Core exercises should be performed about three times a week. You can overdo your core muscles just like any other muscle group, so there’s no need to do them everyday.
When it comes to defining your abs, situps and crunches aren’t the only forms of exercise to really make them pop. Below are five exercises that will really put a spin on your next ab workout.
1. Hanging Knee Raise
These hanging knee raises work your full tranversus abdomininis. These are the muscles that hold your stomach tight and flat.
Think of the muscles you engage to suck it in when a hot girl or guy walks by. In addition to working these core muscles, your hip flexors, shoulders, latissimus dorsi, and biceps will also be triggered during this hanging knee raise.
- Hang from a pullup bar with palms facing away from you, shoulder-width apart. Your feet should be together.
- Simultaneously bend your knees and your hips, and tuck your lower back underneath as you lift your thighs towards your chest.
- Pause when your thighs reach your chest, and then slowly lower your legs back to your starting position. Engage your core to avoid swinging in your hips and torso.
- Hang from the same starting position as before. Lift your legs straight up so that your calves and thighs are parallel to the floor.
- Pull your legs up as you exhale until you almost touch your shins to the bar above you. Try to straighten your legs as much as possible while at the top.
- Lower your legs as slowly as possible until you’ve reached back to the starting position.
2. Pushup to Jack Knife
This move involves a TRX strap. If there’s not one available, you can substitute the TRX with a stability ball.
- Come down to the floor on all fours, facing away from the TRX anchor, and slip your feet into the bottom of TRX handles. Push yourself up until you are in a pushup position with your shoulders, head, and hips in a straight line. Only your palms should be touching the floor. This is your starting position.
- Perform a suspended pushup by bending your elbows to lower your torso until your chest is 2 inches from the floor. Keep your core engaged and don’t let the hips sink. Push yourself back up to the starting position.
- While keeping your legs straight, immediately drive your hips upward into a pike position. Slowly lower your hips back down to the starting position.
To perform this exercise on the stability ball, your hands will be placed in the same position on the floor while your toes will be on the ball (shoelaces facing down). You will, however, be doing a decline pushup instead. The jack knife will be performed the same; just keep those legs straight and lift those hips as you pike on up and roll the ball inward.
3. Keep on Planking
This is just your average plank with a little endurance twist. Planks support your whole body weight in one move, while stabilizing and elongating your spine.
This twist on the original plank will work your obliques at the same time.
- Get into a pushup position, supporting your weight on your toes and your forearms. Your elbows should be bent at a 90-degree angle directly below your shoulders.
- Clasp your palms together directly in front of you. Your neck, back, and hips should be in one straight line. Hold this position for one minute.
- After a minute, roll onto your right side. Don’t let anything come down to the floor! Shift all your weight onto your right elbow with your left foot on top of your right foot. Keep your hips off the floor and your right shoulder should be directly above your right elbow. Keep your left hand rested at your waist. Hold this side plank for 30 seconds.
- When your 30 seconds is up, roll onto your left side without your knees or anything else touching the floor, keeping your body weight off the floor. Only your left foot and left elbow should be touching the floor now.
You’ll be planking for a total of two minutes straight. Repeat as many reps in a row without coming down as you can. Keep track of how many minutes you did each week and see how you’ve progressed.
4. Ab Rollout
If you don’t have an ab roller available, you can always use a barbell instead. This exercise should be “a good hurt.” This exercise is not advised for people with lower back problems or herniated discs.
- Place the ab roller on the floor and hold it with both hands, palms facing away from you. Kneel down on the floor.
- Slowly roll the ab roller out, stretching your body forward. Go down as far as you can without touching the floor with your body. Be sure to keep your core tight so your back does not sway. Breathe in during this portion of the movement.
- After a pause at the stretched position, engage your core and breathe out as you start pulling yourself back to your starting position. Squeeze your core here to avoid any stress on your lower back.
5. Oblique Crunch
This is a littler fancier than your average bicycle crunch. All you need is a chest press bench or a stationary bench that won’t move.
This move strictly engages your internal and external obliques. Your obliques are the diagonal fibers that fan out from your pelvis to your ribs.
- Lay down on your right side on the bench with your upper body extended off the bench. Bring your bottom leg forward and hook your heel underneath the bench. Bring your top leg back and hook your toes underneath the bench.
- Stretch your torso down toward the floor, about 30 degrees lower than the bench. Lift your left hand up so that your palm is cupping your head and place your right hand on your obliques, hugging the torso so you can feel them contract.
- Stabilizing with your legs, crunch your left elbow up sideways, bringing it into your left hip as high as you can. Lower yourself back down slowly to your starting position just below the bench. Repeat for 15 repetitions then switch onto your left side.
Tip: If this move is too difficult at first, slide your hips back so that less of your torso is hanging off the bench.
Hopefully these five ab-defining exercises are something you haven’t tried before. Really push and challenge yourself with these new movements — but remember to always engage that core. Enjoy the burn!
