- Personal trainers who have worked with the likes of Scarlett Johansson recommend eating dark chocolate before a workout.
- The brothers Ryan and Eric Johnson say there are many benefits to the routine, including increasing your energy and creating a positive feedback loop.
- Ideally, they say you should eat a third of a high quality dark chocolate bar 15 minutes before training.
Chocolate and fitness are two things that most people do not suppose go hand in hand.
However, for two personal trainers, chocolate is the key to a good workout.
Ryan and Eric Johnson are the siblings behind Homage Fitness, a new line of gyms in private homes across Miami, New York and DC designed to combine high-level fitness with hospitality.
Brothers, who are certified strength and conditioning coaches, have over a decade of experience in the fitness industry.
They are also personal trainers of Scarlett Johansson and have worked with her and other actors in films like "Captain America: Winter Soldier", "Ghost in The Shell" and "Avengers: Infinity" War ̵
"We are always looking for a good pre-workout supplement but the most some of the things you can buy in stores are full of sugar and caffeine, "Eric told INSIDER
" We already drink too many coffees and even most of our customers do that, we wanted to find something that was more naturally organic and that could give you the same benefits. "
The benefits of chocolate in moderation are well documented.
The brothers say that good quality dark chocolate (ideally at least 70% cocoa) has been shown to release endorphins that make us feel good.
What's more, a recent study found that people who eat chocolate three times a month have a reduced risk of heart failure by 13%, compared to those who have not eaten it. anti-inflammatory, chocolate is bound to live longer.
"Dark chocolate releases dopamine and has many benefits such as vasodilatation which is basically the pump that people seek after trying to build muscle," continues Eric.  "It also improves the functioning of your brain because it stimulates the brain cells to release that dopamine. It also releases serotonin which will soothe the nervous system. "
Science aside, fitness gurus encourage people to take the habit of eating dark chocolate before training for psychological reasons.
" Create this cycle of positive feedback with your brain – Now that you're taking this piece of chocolate before training you're creating a positive association with your training session and you're getting more and more excited about going to the gym … you have something to look forward to, "Ryan says.

They add that it's dark chocolate is also simply a great source of essential energy.
"If you go into your session on an empty stomach, you probably will not last or you may feel a little sick," Ryan continues.
"But at the same time time, if you have too much food, you often feel a little mired, heavy and lethargic. So we found that the bit of dark chocolate does not have much weight but is very dense with nutrients and therefore provides the body with a lot of energy while making you feel light in the stomach, allowing you to jump around
Ryan and Eric do not want to say that you should to have only a little square, in fact, we suggest you have about 2-3 pieces, about a third of a standard-sized chocolate bar, or 30-50g.
If you are trying to lose weight and therefore aim to have a caloric deficit, it is worth noting that you will have to put this extra snack in your daily goals: 50 g of dark chocolate generally contains around 300 calories.
"While the benefits of this nutrient-dense snack (such as antioxidant and anti-inflammatory properties alone) outweigh the excess calories, one should certainly take this into account," says Eric.
"Depending on your current physical fitness goals, personal statistics (height, weight, body fat percentage, life measurement) and activity levels, you should calculate the amount you consume to meet your energy intake requirements. "
You must also eat good quality chocolate.
"Don" get the crappy stuff, "say Eric and Ryan." We want high quality stuff so you can reap the benefits of the antioxidants that are going to be there. "
Ideally, the brothers recommend having chocolate 10 to 15 minutes before training – their favorite approach is to make a couple of squares on the way to the gym and let it melt in your mouth.
Occasionally, however, they have not been able to get chocolate correction in advance, which means that only one option remained.
"Sometimes we eat our chocolate when we heat up in the gym," say Ryan and Eric. "People look at us as if we were crazy! "
