How much rest time is enough?

What's more important, the amount of work you prescribe for a workout, OR, the amount of time you rest in between sets? That's a tough question, and my hope is that you're thinking both hold their own weight when gearing up for a workout. We all know the feeling of being exhausted after a set and knowing we need a few minutes to rest before we're ready for the next. But how much time is enough? Because the goal is to come back to the next set as prepared as we were for the first. I hope I've capture you're interest, so tune in for the next 30 minutes and see what the latest research is telling us.
