Yeah it has upsides, that being said you were using it (workout) in combination with a martial discipline, pushups are great too, for anything boxing typically, squats also if your knees can afford it. Now I was more thinking about lifting iron, like that typically https://pic8.co/sh/fC4gbf.jpg It's not that it is bad in itself, it's just that when you're used to do mostly that sort of stuff, you'll instinctively do exactly that in situation, unsurprisingly. It can be a good thing in the case you mentioned for instance, jiujitsu context, just as it can be a rather bad thing, like as I said, you stay camped straight on your feet, facing the the target not even positioned sideways and you'll instinctively give all you have pulling "it" toward you essentially, which in itself is mostly a big useless waste of energy potentially putting you at risk for no obvious advantage unless you do something with it, and that's precisely the missing part in the conditioning, if anything that's where I'm getting at
