> I am not sure if you minimize risk of injury that much. You might get injured on machine or dumbbell if you go heavy.

The thing machines have that free weights don't are in-built safeties, either by design or as a discrete component (e.g. smith machine). The only machine I can think of that you can get seriously injured on is a leg press machine, whereas there are a multitude of ways to hurt yourself with free weights, especially any exercise where you're under the bar. I say this as someone who has historically trained with a ton of emphasis on the Big 5/Golden 5 compound movements (i.e. not machines). The safety aspect is a big reason casual fitness clubs (e.g. Planet Fitness) have no barbells on the premises.

You are right. I meant it if you do excercises “properly” it shouldnt be big difference. But of course that already means freeweights are more dangerous.
