Just my opinion, but I think everything that's been posted in this thread is average to sub average advice if you want to get fit.
I completely disagree with the upper/lower body split and I really hate the classic bodybuilding split (bis/chest, back/legs, tris/shoulders) for athletes.
Basically, I'm going to have to preach for what I do.
I reallllly like Georges St. Pierre as an athlete. He's an awesome individual and an amazing athlete. I loved it even more when I looked at his training videos and his trainer had the exact same training philosophy as I do.
Basically, you train according to what your body does. That means pulling, pushing, the three different planes and unilateral/bilateral work.
Unilateral work is essential. Yes, that means killing yourself doing side to side pull ups and one leg deadlifts.
Here's a great video of Georges St. Pierre training, literally everything he does here, I also do in my workout(though his strength is humbling) and It's extremely functional training. I have no idea what Loiseau is doing, but hey they're the professionals.
Here's another video of him workout unilaterally. Notice the one leg squats on a bench(which although is one of the first progressions, he's doing with a ton of weight) as well as the dumbell snatches and weighted squat jumps. I wouldn't recommend the DB squat jumps as you can hurt your knee, but you can put some weights on a barbell 1/3rd of your squat weight is generally a good rule of thumb:
Here's two exercises which I am literally always at awe when I see it. I can only wish to be this strong, but imo these two exercises can make you a million times more explosive. My favorite lifter is Iranian, but he's a genetic freak so I'm going to post a guy my mom and grandma know through his brother, just to give him props:
The clean and jerk.
His technique is a bit off here but he's lifting an absolutely insane amount of weight.
Here's another good video of the type of explosive work I do in every workout. I often use this as a tabata HIIT workout:
If you're interested in more info on this type of training, I've put my workout excel sheet in a thread in the Lounge forum. I don't think it's updated though as the update has a lot more detail in it. The basics are basically that on a 3 day workout you do full body and on a 4 day split, you do push-pull... but the quality of the exercises as well as the training intensity are both essential.
try to push the tire down versus one of your friend... Realy nice for core muscles...
If you want to improve your strongman exercice give a try in the gym to some bigger bar, bigger grip dumbell or stuff like that, if you don't try something like www.fatgripz.com, I have some and realy love them.
Bigger grip gonna helps you alot in any pull exercices too.
