1) Use towel to wipe the machine you were using. No one likes to lie down on a sweaty bench!

2) Re-rack your weights. Forget all the ”It was there when I came!”, just do it!

3) Grunting is OK, consistent screaming is not. I’m happy you’re pumped up, but it breaks my concentration if I can hear you over my music.

4) Don’t be egoist and share the machine you are working on, no one wants to stay in line.

5) Try not to walk in-between mirror and someone who is doing exercises.

6) Give people their space. Keep a comfortable distance from others when performing exercises.

7) Don’t start a conversation with someone while he/she is lifting.

8) Don’t say you are using the equipment when all you are doing is resting on it.

9) Help out other muscle builders, if you are asked to spot – do it! You will need their help one day… believe me.

10) Be polite!

And, please, don’t come to the gym naked like those guys in the picture.
