Jennifer Aniston has a sculpted and beautiful body at 53 years of age. This is, in part, thanks to the 15-15-15 routine she performs. It’s important to remember that the results shown by the famous actress are also due to the discipline she professes towards sports, training daily. In addition, she complements this routine with a healthy eating plan according to her needs.

In this article, we’ll tell you all about how to perform this famous routine so you can follow the steps of the co-star of Friends.

What is Jennifer Aniston’s 15-15-15 routine?

According to what the famous actress revealed at some point, after suffering a physical injury she had to change her training method, focusing for a while on Pilates. However, she said that she missed doing a cardio routine that made her sweat enough. So she started implementing the 15-15-15.

She commented the following:

I need some kind of movement, even if it’s just 10 minutes a day on a trampoline…. I was missing that kind of sweat from when you train hard. So I’m going back to my 15-15-15 method. -Jennifer Aniston

But what is this workout that’s already stealing headlines? It’s simple but efficient!

It’s a combination of treadmill, elliptical, and spinning for 15 minutes each. Although this series has worked very well for the star of movies like We’re the Millers, today, there are countless variations, depending on the needs and goals of each person.

There are those who prefer to perform triads of exercises such as running, jumping, and squats. Likewise, there are others who modify the time for each movement, reducing each one to 10 minutes.

The objective is to adhere to long-duration routines, combining high and moderate intensities. This keeps people from getting bored in their day-to-day workouts.

What are the benefits of the 15-15-15 routine?

The first thing to say is that this type of high-intensity cardiometabolic workout breaks the monotony of traditional routines. It allows people to make better use of their time. At any time of the day, the 15-15-15 or 10-10-10 method can be executed, without worrying about the opening or closing time of the gym.

It’s also worth noting that it’s not necessary to perform the 45 or 30 minutes of exercise in a row. You can complete the time in two or three batches throughout the day.

Those who have machines at their disposal can even do it Jennifer Aniston style: combining elliptical, treadmill, and spinning. On the other hand, those who prefer to do other activities, have at their disposal jumping rope, walking, outdoor running , and squats.

There are those who may doubt the benefits and impact on the body of these mini-workouts, but it must be said that scientific studies claim that this type of cumulative exercise has the same benefits as a continuous routine.

The disadvantages of this method to keep in mind

Lo ideal es combinar la rutina 15-15-15 con trabajo de fuerza, así se obtienen mejores resultados.
Thekey is to combine the 15-15-15 routine with strength work. This way, you get better results and complement the aerobic exericses.

Rather than “disadvantages” of the 15-15-15 routine, we’ll simply talk about what things should not be left out when you start with this method. Physical activity is very important and, according to the World Health Organization (WHO), it prevents different diseases, such as heart disease, diabetes, and even cancer.

It also reduces symptoms of depression and anxiety, improves memory, and enhances the health of our brain.

However, this routine must be complemented with strength training to tone muscles. Cardiovascular exercise, such as the 15-15-15 routine, burns calories, but does not increase muscle mass. It’s key to preserve lean body mass so as not to suffer from sarcopenia or lack of strength during aging.

It’s not a matter of prioritizing either strength training or cardio. Instead, it’s about the combination of the two that’s most beneficial. In fact, a 2020 scientific analysis established that just 6 weeks of both movements is enough to reduce women’s body weight without reducing the amount of muscle.

Because the basic risk of focusing on aerobic exercises is to neglect muscle toning. Sometimes, in the pursuit of a type of silhouette, we don’t give enough importance to muscle tissue. And although we may not notice it now, as we age we will need active and healthy fibers in our muscles, which will allow us to move around and do our daily activities with less effort.
