Come prepared to the gym with a written work out plan . Being properly prepared is key for success ! Know what you’ll be doing before you get there. Plan it right before you go to the gym, the day before, or better yet use the strategy I use. If possible, schedule your workouts around peak hours when other gym goers are also trying to fit in their workouts. This will help you get more done in a shorter amount of time simply because you won’t be waiting around or fighting people for the workout equipment you need.
Also make sure you have a set good rest time between your workouts to maximize your time.
