If this isn’t a stunt double than congratulations to the guy.

Not many influencers like himself go out there and try challenges like these, they seem too caught up in their own wealth and popularity.

As for the technicalities behind his strength etc. I’ve never done a Ninja warrior challenge or anything particularly related however I have trained under different types of exercise, calisthenics, weights, joint strength and explosive mobility, ‘farmer strength’ etc.

To do any kind of challenge like this you need two things:

– Cardio Endurance
– A good bodyweight to strength ratio

Marshmello looks quite fit, his physique isn’t good calisthenics trainer level but it’s still enough to pull off what he done here.

Exercising and training is more complex than some may think. Having big muscles isn’t the only for attaining strength, joint strength and mobility is actually important as well, this is how Bruce Lee was so strong.
