Tips

With the right diet and workout routine, getting a six-pack in 30 days is totally possible. The key is doing exercises that work out your abs and core while reducing your body fat as much as possible. We’ll give you all the workouts you need to emphasize your ab muscles, plus dieting tips to help you trim belly fat and show off all your hard work. Remember that all bodies are different, though—if it takes more than a month for your abs to show, that's OK. Getting in the right habits will get you there eventually, so let's go!

Best Ways to Get Abs in a Month

Do exercises that build your six-pack (rectus abdominis) muscles, like crunches, planks, sit-ups, and hanging leg lifts. Additionally, work your inner core with bridges and side planks, and integrate cardio exercises like running or cycling to burn the fat covering your abs. Exercise 6 days a week, 45 minutes a day.

Try to focus on the way your clothes fit instead of reading the scale. If you’re adding muscle mass on top of losing weight, the reading may not change much, but your clothes will probably feel looser.^{[26]

If your goal is to lose body fat, try to stick to a healthy eating plan, not a diet. An eating plan just adjusts what you’re already doing, while a completely new diet can be hard to stick to.^{[27]

There’s no way to target belly fat specifically—your genes, gender, and age all control where your body stores and loses fat. The best way to get rid of belly fat is to focus on losing weight in general.^{[28]

Tips from our Readers

The advice in this section is based on the lived experiences of wikiHow readers like you. If you have a helpful tip you’d like to share on wikiHow, please submit it in the field below.

Calculate your body fat percentage first before beginning any workout plan. Knowing where you stand will determine if you need to focus on fat loss through diet and cardio before your six pack will become visible. Use an online calculator to get an estimate.
Perform exercises like crunches, planks, and hanging leg lifts that specifically target your rectus abdominis, the long muscle that makes up the six pack. Work this muscle group to hypertrophy so the ab outline grows more defined.
Maintain a high protein diet with foods like fish, Greek yogurt and eggs. Protein provides the amino acids to build and repair muscle fibers broken down during training. Shoot for 0.5-1 gram per pound of body weight daily.
Incorporate bridges, flutter kicks, and other moves working your entire core region. Having a strong overall midsection provides an inner "corset" to support and showcase your six pack muscles.
Limit unhealthy processed foods like chips, fast food and frozen meals. These items tend to be high in sugar, unhealthy fats and sodium which promote fat storage around your midsection.
Log everything you eat each day in a food journal or app. Monitoring your nutrition helps ensure you stick to your plan and serves as extra motivation to make healthy choices.
