I started going to gym with my wife and we are focusing on strength exercise. We do rotations (by doing 5-8 times on max weight we can do for that specific muscle training) on each gym apparatus then moving to next one until we are done with all gym equipment. We then take a 5-10 minute break and do another round. 3 rounds in total which usually take 90-100 minutes in total including resting. I also try to switch between arms and legs to give more rest to muscles. I have noticed that some people that are coming to gym (that do seem quite fit) do same type of muscle training 3 times on one machine and only then move to different one. The way I understand muscle growth is all about ripping the muscles not tiring them out.
Which way is better for strength: do one type of training at once or rotate different ones and save time needed for resting (or neither)?
