Abs is the shortened term for your abdominal or core muscles. The ab muscles are located in the trunk of your body under the chest and above your pelvis. Doing ab workouts can directly impact nearly every movement you do during the day including sitting up in a chair and walking across the room.

Ab workouts help you build strength throughout your entire body, improve your balance, and reduce your chance of injury while doing full-body movements like push-ups.

There are many different ab workouts that can help you get into shape. Several of these exercises don't need equipment and can be done from home including floor ab workouts, standing ab workouts, and easy ab workouts for the beginner. If you have access to a gym, some core exercises you can do using fitness equipment, like cable ab workouts and medicine ball workouts.

Ab workouts at the gym 

A major benefit from going to a gym for ab workouts is the social environment.

Being able to ask other members or staff members questions on correct form or additional workouts can be a great help to your own fitness. A gym will also give you access to numerous pieces of fitness equipment that most people don't have at home. 

If you decide to do your ab workouts at the gym, here are a few that can get you started (detailed above):

  • Standing Cable Crunch
  • Cable Twist
  • Kneeling Cable Crunch
  • Ab Toss Roll Up
  • V Sit With Weight Pass

Before you begin a new workout routine, it's a good idea to talk to your doctor. Ab workouts shouldn't be painful. It's likely you will feel a little sore afterward, but if you experience any sharp or long-lasting pain, check in with your doctor. 

Always do a warm-up before an ab workout to help prepare your body for the movements. A simple warm-up is to march in place while swinging your arms to activate the core. Start with a few exercises with low reps. Once you feel comfortable with the movements and your form, you can gradually increase the amount and duration.

Make sure you understand the proper form for any ab workouts you do, since poor form can lead to injury. If you need help, talk to a fitness professional, look at example photos, read written instructions, and watch videos if available.
