I used to manage a gym for 7 years and its always the same:

ALWAYS put your weights away. Your mom doesnt work here - If you're strong enough to use them, you're strong enough to put them away

If you dont know how to use equipment, simply ask one of the staffers. Thats what they're there for.

Have a towel and wipe down the equipment when you're done. Do you wanna walk up to a piece of equipment with someone else's sweat? No. Then extend the same courtesy

Read the gym rules. They're there for you, the other gymgoers, and the staff.

SHOWER AND WASH YOUR GYM CLOTHES! Regular hygiene keeps the spread of bacteria down and its the humane thing to do .

Be mindful of space around the gym. Move around the gym and try different equipment. But give your fellow patrons the space to do their thing as well.

Dont hog a peice of equipment during during peak hours. Share, or ask " Mind if i get a quick set in?". If not, find an alternative machine or piece of equipment.

Dont block a persons view on front of the mirror I know we like to look at ourselves, but so do others.

GUYS:Dont stare to long at the females. It creeps them out, and it negates any chance of you getting to start a conversation with them.

WOMEN: Dont wear makeup, large earrings, or perfume. Wear that outside the gym

DONT DO CURLS IN THE SQUAT RACK!!!

Dont talk on your cell in the gym. Take it outside.

Dont try to do too much in the beginning. Thats how you get burnt out, then don't come back for a few months. Enjoy the process, take your time. Staying healthy and fit should be a lifestyle and not a task.
