Less is More.
LESS IS MORE.
It's time to put your money where your mouth is. You say you want results. You say you're willing to work hard. You say that you are done with excuses. So here it is; the no-BS method to achieving outstanding results. It's time: put up or shut up.
The concept? Less is more. No more myriad of exercises. No more "hitting the muscle from 100 different angles", no more hitting the body with tons of stuff to keep it "confused". No more "Mr Kimble I need the bathroom"; THERE IS NO BATHROOM!
Pick 2 main exercises, and 1 core exercise. That's it. That's your workout. Simple, effective (some may even say "sinister" haha...).
Now it's up to you what you choose. I deal in concepts. I deal in principals. If you understand them, you can apply them a zillion different ways. I prefer 2 opposing exercises, like pushing / pulling. If you're only going to choose 2+1 exercises, you need to figure out what will give you the most bang for your buck. You cannot afford to waste effort on silly abstract exercises that don't offer a big return.
I work with kettlebells, so for me the answer is simple: my go-to 2 exercises are SWINGS and TURKISH GET UPS. Swings are ballistic, and the TGU is a grind - offering me the best of 2 very different principals. biomechanically swings are virtually the same as a deadlift or a standing jump. So I am training deadlift mechanics, I am training jumping mechanics. The exercise is a movement pattern, so try not to think in terms of "what muscles is it working", because the answer is (almost) ALL OF THEM. The TGU is complex and offers numerous benefits: proprioception, mobility, stability, strength, movement, stamina... time under tension. To name a few.
My 3rd, my core exercise, will always be one of the following: Ab wheel roll outs, leg raises (hanging toes to bar), or dragon flags. Those 3 beat just about everything else when it comes to targetting the core, the midsection.
But hey, you might not be that into kettlebells. Here are some ideas for you:
Deadlifts & dips Front squats & pull ups
Or if you have the technical skill:
Clean & Jerk Snatch & a Loaded carry (farmers walk, Conan carry, etc)
If you can get REALLY GOOD at just 2 main exercises, and 1 core exercise, trust me, your gains will skyrocket. Stop trying to do a million different things. Narrow your focus and become ridiculously good at just 2+1. Remember what Bruce Lee said? "I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times."
Practice your chosen exercises 10,000 times. Get REALLY GOOD at something specific, and watch how everything else improves.
Now go become a superhero.
