I was discussing this with another guy some time ago. We were looking for ways to help up his conditioning a little as well as make his time more efficient in the gym.
What we discovered was his training sessions would last 1 1/2-2hrs long sometimes.
Rest periods between sets as well as various exercises lasted far too long. Once we shortened those up, the sessions seemed to take much less time.
Over time spent in other gyms, I've noticed this in lots of other guys as well. They do a set and then chat with their buddies for the next 10minutes before they do another set
So how long do your training sessions last? Do you take a more leisurely approach to your workout tempo or do you spend very limited time between sets and push yourself hard?
