The show is total bullshit, it's like comparing how a NFL star versus some soccer fag would do in a fight. They only take into account the weapons they use. The difference in field tactics, and the size of each army is fucking huge.
A roman soldier couldn't fight one on one with a celt to save his life, yet in formation the romans were unstoppable.
What makes you say that?
The Roman legionary was a professional soldier who trained every single day. For the majority of its existence its troops were not conscripts and they had to pass a physical examination and be a minimum height before starting training.
They would train with with wooden weapons and shields double the normal weight and practice against wooden dummies and also spar with each other. With shields and without.
They would also practice sprinting in full body armour, cross rivers in full armour, do long jump in full armour and jump across ditches.
They also ate extremely well for the time on a staple diet of polenta and meat. So they had a high carb diet with a bit of protein as well.
They also had access to experienced trainers and trained in knowledge gained from previous wars and also gladiator sword masters as gladiator fighting was basically their national sport.
Plus they had excellent armour in comparison to the Celts or any barbarians who fought half naked.
They also had good doctors who could were only held back by lack of medication to prevent infection, even though though they could perform advanced surgery for injuries. They even had physiotherapists for injuries.
