Greetings! Question for the Apple Watch users in the gym/tracking fitness.

1. When doing resistance training, for each different workout - like a chest press versus a shoulder press, do you do it as one Apple Watch workout, or two different ones? I’m new so I’m not sure which is better, I do it was one workout, under resistance training

2. My second question is if you do is as one workout, would it be accurate to break them up by “segments” I.e. chest press is one segment and shoulder press is another segment under one workout.

Also open to correction or different approaches since I’m a real noob to this, thanks in advance
