Sumo wrestling is the national sport of Japan and is considered to be one of the world’s oldest organized sports.
Wrestlers belong to stables where they eat, sleep, train and breathe everything sumo. They start their days around 5 a.m. They skip breakfast and go right into a 3-4 hour training session that focuses on flexibility, balance, strength, speed, stamina, and stance.
Then they eat a long lunch, consuming around 10,000 calories all chased with a hefty quantity of beer, followed by a long nap.
So, let’s recap: Sumo wrestlers wake up and skip breakfast to train for several hours on an empty stomach, then they eat, drink, and take a nice long nap.
After the nap, they wake up, eat and go back to sleep again.
Training that hard on an empty stomach pretty much deprives their bodies of the calories they need to fuel their training, which then triggers the hormone cortisol into overdrive, directing their bodies to store as much body fat as possible in response when they actually do eat.
So, no wonder Sumo wrestlers are built the way they are. This approach to training trains their bodies to convert the calories they eat into fat storage rather than allocating them to where they could be used more effectively instead.
