Not timing your rest periods

According to Jason Ferruggia, head strength coach at Renegade Strength and Conditioning, most guys should be in and out of the gym in 60 minutes, including warmup, cool down, and a good lifting session. To make that possible, avoid wasting precious moments in between sets of an exercise.Wear a stopwatch or use an app on your phone to limit yourself to under a minute. Youll be amazed at how quickly youll finish your workout.
