I'm in great shape, will basic training keep me here

[Looks228]

I am an 18x and I'm in the best shape of my life. I am 20 years old, 6'1 and 194lbs. I've been doing crossfit for the pat 6 months. All I wanted to know is if basic training is going to be anywhere as high intensity as my past 6 months. Will I get weaker? Will I lose weight? Or is it only up from here? I ship October 13th to fort benning to begin my journey
