So I am new to the gym. I had an induction session where I was told to do 30 minutes of cardio then use the weights machines. There are about 6 machines, each works different muscles. I was told to do 3 sets of around 12 reps resting in between each set. If each machine works different muscle groups is it ok to move from one to the next doing one set on each without resting. Or do I really have to sit there for 2 minutes between each set and do one machine at a time?
TIA as I say I am completely new to all this but want to build some muscle to help with weight loss.
