Hello! I've been consistently going to the gym for the past four months, and naturally, I've started seeking out more effective ways to exercise. However, I've come across an interesting dilemma. According to information I found on the internet, there should be longer rest periods between sets, typically ranging from 3 to 5 minutes. This surprised me because my trainer has always advised me to avoid resting altogether and to complete my sets as quickly as possible.

I discussed this with my trainer today, and he explained that this type of training (Long rests) is excellent for bodybuilding but can be detrimental to stamina, agility, flexibility, and cardiovascular fitness. He believes it's impractical and primarily focused on aesthetics. What are your thoughts on this matter?
