This is one statement that is very true. Less is definitely more when it comes to bodybuilding. If your sessions are lasting over an hour, you are either doing way too many exercises and need to curtail it to include more compound lifts and less isolated movements or you are just taking extended rest intervals.

You want to get in the gym, do an intense workout and get out.

Working out past an hour could have you seeing rapidly declining blood sugar levels along with a decrease in testosterone output. Your cortisol release will also start to go up, which is a catabolic hormone that will promote muscle breakdown and fat storage.

If you can’t seem to get your workouts under an hour, then it’s likely time to have a look at a specific exercise selection or your workout split of choice. If you are trying to do a full-body plan three times per week for example, it may be better to look at doing a four-day, push-pull type of split instead.
