Alex Rodriguez's girlfriend Jaclyn Cordeiro is a fitness trainer and thus knows that hitting the gym alone doesn't guarantee a peak physique. Nutrients, stress levels and metabolism play an essential role in transforming the body.

In her latest post, Cordeiro highlighted one essential nutrient that plays a vital role in stress relief, digestion, heart health and muscle recovery — magnesium.

On Wednesday, Cordeiro shared two graphics with important information highlighting six different types of magnesium and their benefits. These are as follows:

Citrate: Helps with constipation
Glycinate: Supports stress & sleep
Malate: Relieves muscle pain
Oxide: Aids indigestion
Taurate: Supports heart health
L-threonate: Enhances cognition

In another snapshot, she provided a list of food items rich in magnesium. They are as follows:

Almonds (dry roasted)
Spinach (boiled)
Cashews (dry roasted)
Peanuts (oil roasted)
Shredded wheat cereal
Soy milk (plain)
Black beans (cooked)
Edamame (shelled)

As a well-known health coach, Cordeiro is no stranger to promoting wellness. With her “JACFIT” brand, she continues to educate and inspire others.

Alex Rodriguez's girlfriend Jaclyn Cordeiro highlights important of 80/20 rule in fitness

The 80/20 rule in fitness is widely followed in the health and wellness industry. It suggests that 80% of results come from nutrition and 20% from exercise.

However, there is another explanation for the rule, which advises people to eat clean and train 80% of the time, with the other 20% allowing for some flexibility.

During an interview with Bloom TV in February, Alex Rodriguez's girlfriend Cordeiro highlighted that the 80/20 rule is at the center of her six-week fitness transformation program.

"I do teach my clients the 80/20 rule," Cordeiro said (6:50 onwards). "So, 80% of the time, I would say if your diet and training are in check, you're good. That 20% might mean that you're going to go out, say, with your partner and have a nice steak dinner or whatever—maybe a glass of wine—but perhaps defer the bread and the dessert."

"Something a little bit off of the regular menu 80% of the time is just enough to make you enjoy life. You still have to enjoy life, right? It can't be an all-or-nothing mentality because when you do that, you set yourself up for failure. But yes, the 80/20 rule is definitely a strong model in the JacFit program."
