I mean, if you do weighted muscle-up you do weighted pullups, shoulder internal rotation and dips in one exercise. Are there any gains from such mixed up exercises? What about w.pull-ups with leg lifts, leg extensions(with weights attached to feet) with doing sit-ups or bench press on a bench simultaneously(at the same time), reverse hyperextensions and lying rows at the same seconds(like you lift both legs and dumbbells in hands),
I mean, if you put aside the obvious awkwardness(and I train at my basement so no one sees me), one can really save time with this method, however I don’t know if there will be any strength or mass gains. Like you can attach weights to feet on hyperextension bench, lying on it do a ham curl, leave feet raised, do a reverse hyperextension with this weight (maybe not max weight but still some training), and while doing this also perform a rear delt row with your arms. Job is eating my time, so if this kind of training works, (even if you can’t do it with all muscles) it would be great.
Also it demands more energy, maybe there will be more natural testosterone etc generated in body with it(like “big muscles generate a lot of natural anabolics”, maybe few small muscles together generate the same amount of testosterone etc)?
