Why does p90 work

And although there is plenty of anecdotal evidence that suggests the program is effective, no scientific studies have been published to determine the true energy cost and exercise intensity of P90X. Until now. Led by John Porcari, Ph.

To first establish fitness baselines, researchers performed maximal exercise testing on each subject using a motorized treadmill to determine max heart rate and VO 2 max. Although P90X is comprised of a dozen different workouts that alternate from day to day over the day training period, researchers chose to analyze these four because they best represent P90X as a whole. Once each subject was proficient in the workouts as deemed by the research team, actual testing began.

The subjects exercised to the best of their abilities e. Due to the intensity and wide range of motion required by P90X, subjects were unable to wear bulky metabolic testing equipment.

Caloric expenditure was later calculated from the same VO 2 data. At least 48 hours of rest was given to subjects between each workout test. The Results After weeks of testing, the research team crunched the data Table 1. Porcari and his team reported that the average heart rate for all four workouts was 67 percent to 83 percent of HRmax for the male subjects; 65 percent to 88 percent of HRmax for the females Figure 1.

Meanwhile, the calculated VO 2 max values were between 45 percent and 70 percent of VO 2 max for males and between 45 percent and 80 percent for the female subjects. As for calorie burns, the male subjects burned Male subjects totaled to kcals burned per workout. The females expended a total of to kcals per workout. Researchers noted that given these results, the P90X workouts that were tested and, therefore, most likely all of the P90X workouts meet or exceed established fitness industry standards for losing weight and improving cardiorespiratory fitness.

Still, there are a couple more things to keep in mind. Porcari also cautions against putting too much faith in the calorie-burn numbers typically advertised with programs similar to P90X. Critical reviews of P90X2 say it's not as good as its predecessor P90X and even go so far as to call it "boring.

P90X3 offers intense, 30 minute workouts. Known as the "excuse buster" workout because of the short workouts, users should expect fat loss and increased muscle if they follow the schedule and prescribed nutrition plan. Like other P90X programs, you'll need hand weights or resistance bands. You'll also need a chin-up bar and a mat and some room to move. Depending on which workout you do, your effort and body composition, you may burn around calories in a workout.

On the other hand, The Fitnessista complained in her review that the workouts weren't challenging enough and said there was too much joking around and chit chat from Horton during instruction.

For example, this can be as simple as going from only being able to do 1 push-up to being able to do 2 push-ups.

You progressed from 1 to 2 so your muscles will automatically get stronger. See what I mean? You progressed from 1 to 50 so your muscles are now bigger and stronger.

Logic and common sense FTW, none of that muscle confusion silliness. Professional athletes train times per week, so why would an average Joe who simply wants to lose weight and look better need to workout every single day. The answer — there is no need to train 7 days per week. Granted some of these days are more relaxed than others yoga and stretching but still, training 7 days per week is unnecessary especially if your goal is to simply look and feel good which is probably what most are trying to accomplish.

Will P90x get results if you do it? Yes absolutely, but it is by far one of the least optimal approaches to losing weight. When it comes to fat loss, one of the best approaches to working out is to simply train times per week to mainly preserve muscle mass, and to let your diet create the majority of the calorie deficit and burn fat. Sorry, eating every hours does not boost your metabolism.

Check out a sample day of how I eat here. Dieting is a lifestyle change but do you really want to live a lifestyle where you have to eat every hours on the clock and can only eat a specific list of foods. You want to live a life where ice cream and doughnuts are regularly involved.

His approach makes it super flexible and easy to lose fat. People in category 1 are typically the beginners. Those in category 2 have probably already tried losing weight in the past with no success.

Perhaps they went to the gym and had no idea what they were doing or perhaps they had a bad experience with a personal trainer that touched them in weird places. Now they simply want to stay in the comfort of the home and maybe give this P90x thing a shot. Category 3 people are those who are already familiar with working out but want to give themselves more of a challenge. To be completely honest, the only people who should do P90x are category 3 people.

If you find yourself in category 1 or 2, P90x is going to be overkill for you.
