The Galaxy Gym is a very helpful place where you can work out and raise your stats (speed, strength, endurance, or panic) for a monthly fee. The gym is divided into five sections: Research Catalog, Training Facilities, Personal Trainer, Nutrition Center, and the Bathroom.

Research Catalog
The Research Catalog is an important part of understanding the gym and learning how to train your alien. That way, once you go to the Training Facilities and start exercising your alien, you won't be confused by all the different terms. In order to help you out with this, the catalog has short descriptions about all the battle stats and the different courses you can find at the gym.

Personal Trainer
James, the personal trainer, provides three small functions for a minimal fee each day. Basically, if you pay James his fee before you start training at the gym, he'll let you see your stamina bar so you know how much stamina you have left while training. Also, he'll let you see the previous day's gains (if you worked out the day before) and in addition the total amount of stats you have gained in the gym. James is worth the fee just to be able to see your previous day's gains because that will allow you to understand what you are doing right/wrong with your training.

Training Facilities
Here is the main part of the gym. You have several different courses to choose from - ranging from easiest to the hardest. Doing the harder courses takes more stamina but generally improves your stats more. Also, doing the smaller reps (like the [1]) instead of the larger ones will also tend to give you higher gains in that statistic. Those are some of quite a few tips and tricks that will let you gain more and more stats - after you've learned how to work the gym for a while you'll figure out most of the "short-cuts."

Nutrition Center
The Nutrition Center sells different concoctions that will give you some more stamina so you can train in more exercises. However, all the energy drinks are not free and as you get older, all the prices increase. Just like in the training facility, there are different tricks to learning which energy drink to buy and how many times or in what order. As you get older and interact with other players and your guild, you'll find out the best method.

Bathroom
The bathroom is a completely pointless place - just there for shits and giggles!
