You can go to the gym seven times a week, but not at once. This means you need to choose a time when you feel rested and not too tired.
This will help you stay motivated and keep you energized for other activities.
Also, ensure you eat healthy during these times. This will ensure you don't feel tired and sluggish when going to the gym.
Last, make sure there aren't any other things competing with your time. For example, if you have children, you may want to avoid exercising on school nights as they will distract you from your workout.
