Depends on how you've lived your life and what branch you're going to. The physical stuff is of the least of the concern to most of people, it's the psychologic part most have trouble with.
Being in -40 degree weather with your feet wet surprisingly is more of a mental challenge than physical. 30's weather with rain pouring down and wind blowing at a hill top, unable to use your raincoat because you have to use it to protect delicate equipment...not being able to use gloves in that -40 weather because you have to use a pen all the time...
Those are extreme weather cases, then there is the pressure from the superiors, they will try to break you. They will try to make you commit mistakes. They will bully you.
Many people, that seem tough and rugged, can't deal with it. Many will still go through the training but it will change them a lot. Military service will change almost anyone.
I have served my mandatory time, fire control NCO in artillery, meaning frontline training. While it might seem glamorous for a young boy, being in the military, it really isn't that. It's demanding and a lot of the times you wish you were somewhere else. In my case more than half of the time was spent in the woods living in a tent (sometimes not even that, and if yes it depended on whether you had the time to sleep or not), arctic conditions, not in cosy barracks.
