I don't think most here actually prioritizes strength work, S&C, etc. over technique and skillwork. Your body adjusts with a new stimulus, and maybe in a week or 2 will be able to handle heavy lifting and training. Of course heavy lifting for us does not mean a full Russian PL type routine, thats way too taxing for most.
You also have to see the types of people posting here, its likely not alot of posters are top level UFC fighters, they're hobbyists and low to intermediate level competitors. Posters who ask questions about S&C work are usually people who like MMA/BJJ/Striking, got into it, started competing, but never had an athletic base growing up; So at that stage of development, a basic program goes a long way, and benefits much more than endless circuits and running.
At the big picture, ignore it, there is no negatives to it:
- Your metabolism increases significantly (you can eat more food)
- You get stronger
- Address muscle imbalances (a huge issue with combat sport practitioners)
- Usually if planned right your explosive strength improves as well
Thats not to mention as well, if both of you have similar a skill level in a contest in something grinding like the clinch, and your opposition is weaker, they'll exert much more energy trying to match or overcoming you.
The problem is it takes time to show. New guy can show up to BJJ x5 a week and in a month he'll be able to escape mount under a heavier guy. For the strength to reap its reward, its gonna be at least 4-12 months before significant usage appears. So really its a long term investment.
My problem is coaches not accepting that people have different body types/needs and not everyone is meant to be a thin lanky striker; Telling people to lose muscle to murder themselves to be weak, lethargic, and flat is not what should be happening. I've experienced it myself, seen teammates and others (from sister gyms) get mauled by fighters who have done good strength work, and despite them being shorter, they dominated. Quite a of those guys had finishes as well. Height is an important attribute, but its not the be all end all of things.
Also it depends on your stage as a fighter, at the novice level things are very aggressive and athletically fueled, little to no technique is used due to lack of exp. nerves, etc. Being athletic and strong at this stage counts for alot, once a fighter reaches the late-intermediate to advanced (10+ fights), is when technique and tactics really start to shine. I'm mostly referring to striking in this.
GSP: Thats to say the strength work didn't help him. Benching 315 is a huge strength milestone for alot people and he's reaping the benefits of it.
Its like winning the lottery, then saying you did it because you enjoy it which is fine. But after winning the lottery, you buy 3 super cars, and a 4000sq ft home, and say it did not help with that is misleading.
