The Order In Which You Perform The Exercises

Exercise selection is important but not as important as the order in which you perform the exercises, and if you have that luxury, you should be thankful.

I, myself, have worked out at commercial gyms most of my life and do not have the time to wait for a piece of equipment to open up, nor would I wait for piece of equipment to open up even if I did have the time. And I especially won't wait for a piece of equipment to open up in the middle of a workout.

Remember, you only have a certain amount of time before your body enters a catabolic state and begins to use the muscle for energy, some say 45 minutes.

And if you do have that luxury, you might want to consider performing a compound movement followed by an isolation exercise or visa - versa, an isolation exercise followed by a compound movement to try to create a more anabolic environment / state within your body.
