If you wish to pick xfit over casual weight lifting at gym to get in shape . I am sorry, none of those will help you to get in shape . Get a great coach first who is not full of shit (to tell if coach is a shit, ask if he sells meal plans, if yes, than he's a cunt without knowing it himself) or also, do a good research yourself, spend 2-3 hours a day for few months on reading material about lifting and nutrition. (Not Men’s health or Mike Сhang horse shit) . After all you can even get at some shape doing crossfit ( but but...wait Aidas, but didn’t you told us its utter shit?) yeye, it is a shit, you got it right *kisses*. Guys on strength routines or hypertrophy routines just after a year look far better than most of xfit gurus. Yet, some greatest minds of bodybuilding and powerlifting has managed to put that chaos together and make something useful out of it. However, those workouts become mandatory to do in order to achieve goals, you will have to repeat them all the time and you will most likely get bored (because it would be just like any other strength/ hypertrophy program). Nevertheless, I find it funny that guys who done crossfit for 10 years barely outmatch those who done it for a year or less (depends on how obese / weak person was, but mainly obese). If we compare people who do powerlifting/bodybuilding for 10 years to those who done it for a year or even four years... Son… Difference is gigantic, and I am not talking about AAS, human genetic plateau does exist, but it does not stop.
Let me just say like this, if powerlifting did not exist, Crossfit would look like amateur gymnastic mixed with kettle bells. I mean, nobody would care about those huge plates and bending bars only at 50kg of weight, it would look point less and stupid. Why not just make out of paper 10-meter Mountain and lift it? I mean, it is massive, right? As for functionality, you could as well do gymnastic instead and get actually far greater results. But crossfit is just another interval training - HIIT excercise (the type of cardio), it was designed for years ago, just with xfit you most likely wont get any specific results .Seriously, xfit workouts make absolutely no sense IF your goal is to train for a specific athletic event or to gain muscle.
Even strength lifting and hypertrophy should be done with a correct routine based on persons level, if person comes and does random exercise, gains will come years late. And remember, you don't have to jump off a cliff to understand that it's a bad idea, you don't have to stab yourself to understand it's a bad idea, you don't have to do a crossfit to understand that it is a bad idea.
Also one of my friends made a great comment:
