How Long Does It Take to Get a Flat Stomach Using Insanity?

The idea behind Insanity is that it's a tough, grueling workout you can do in your own home. The program mixes plyometrics, cardio, upper-body resistance moves, core training and recovery work. How long it takes you to get a flat stomach with Insanity depends not only on your starting point, but also how closely you adhere to the program and how much effort you put in.

  1. The 60-Day Promise

    • Insanity guarantees visible results after just 60 days of following the plan. The program creators are so confident that those who follow the schedule to the letter will be pleased with progress, that they offer a money back guarantee. This timeframe might not be enough for you to get a flat stomach if you're starting from an overweight or obese standpoint, however.

    Healthy Weight Loss

    • While you may be inclined to drop fat and get lean as quickly as possible, your health needs to be taken into account. According to the Nutrition.gov website, a reasonable and healthy rate of weight loss for most people is around one to two pounds per week. As Insanity lasts just under nine weeks, you should be looking to lose nine to 18 pounds in that timeframe. If you think you've only got this much to lose until you have a flat stomach, then one round of Insanity may be enough. If not, you might need to complete the program a few times over.

    Stepping Toward Shredded

    • For some, a flat stomach simply means no wobbly bits, while for others it means a shredded six-pack. Give yourself enough time to diet down if your goal is to be extra lean, advises nutritional scientist and bodybuilder Dr. Layne Norton. If you're prone to carrying extra fat you may need 16 to 22 weeks to reach your goal, which would be two to three rounds of Insanity.

    It's Down to You

    • Ultimately, you'll get results with Insanity and can get a flat stomach, but how long it takes depends a lot on how much effort you put in. Working to your maximum, not skipping workouts and eating right will go a long way to speeding up your results -- but taking things easy, missing sessions and following a poor diet will take you further away from your goal. Make mini-goals along the way to help keep you on track and realize that your transformation should be a gradual one, not a fast fad or quick fix.
