-addresses muscle imbalances (HUGE issue in the community, too much anterior work is done, not enough posterior, underdeveloped hamstrings leading to knee injuries are very common)
-increases max strength which increases explosive strength as well
-increased metabolism from activity level
-burns more calories than most cardio heavy exercises
The problem is it takes time, and sometimes the DOMs last for awhile and in camp sometimes time isn't something that is affordable. Strength work for the most part is misunderstood, too many peeps attempt "plyometrics" or explosive work and end up turning it into a glorified conditioning session. Speed work is the same as max effort work, anything more than 3 reps or 10 seconds isn't in that range anymore.
The combat sports community is actually still very stuck in bro-science mindset, actually its worse than bro-science, because at least bro-science works and makes sense. The ones from martial arts is completely retarded at times. Chin conditioning, lifting slows you down, lifting slows down your metabolism (lol), carbs are teh devil, increasing your VO2 max in martial arts is different from football, baseball, because XYZ, etc
