Some good, and funny tips from NerdFitness about how to behave in a gym:
The gym can be an intimidating place. Besides the grunting and the weights dropping, there is a secret code of conduct that is totally foreign to any newcomer on what to do and not to do.
I especially like this one about ‘saving’ equipment when you’re running a circuit routine:
Is the gym busy? Forget about trying to get a squat rack AND a bench AND a chin-up bar. Pick one. There’s the classic CrossFit workout “Linda” that has you using three different barbells with different weights for different exercises, plus a bench (for the bench press). If you ever try running this in a busy gym, people have the justifiable right to throw you out the window.
Absolutely drives me bananas when someone is trying to do a complex circuit at the gym with totally unrelated pieces of equipment that are like a 5 minute walk from each other. I get it, you’re trying some workout plan out. Great. Just be smart about it and don’t screw up everyone else!
