One of the things I like about Insanity is that the workouts are not too long. Most of the workouts are under an hour long. Shaun T developed the workouts so you are doing different dynamic moves that incorporate multiple muscle groups.
This way you’re not working on just one or two muscle groups at one time but instead three or more. It’s a contrast to what is done in the P90X workout where you have an hour long workout followed by a 15 minute ab workout.
You do Plyometric Cardio Circuit, Cardio Power & Resistance, Cardio Recovery, and Cardio Abs. Each one of these workouts is 30 to 40 minutes long. The Cardio Abs workout is 17 minutes long and is only done after Pure Cardio three different times. Even with the additional ab workout you will still finish all of your month one workouts in under an hour and more often around 40 minutes.
You only do the Core Cardio & Balance workout six days that week. It’s about 38 minutes long.
You do Max Interval Plyo, Max Cardio Conditioning, Max Recovery, Max Interval Circuit, Cardio Abs, and Core Cardio and Balance. The “Max” workouts are about 50 minutes long.
The first time you attempt them you’ll probably be saying “10 more minutes of this stuff. You’ve got to be kidding me.” Those max workouts do a lot of the same moves as in the first month but you are going for a longer time. It really is a challenge.
What really makes the Insanity workout a great program is it puts everything together in a short time period. Those times also include a warm up and cool down period.
