What is gym etiquette you might ask.  Just about anywhere you go , there are rules. Yes,, even the gym or health club that you pay a rather nice fee to be a member of. 
For some people rules are rather obvious, but for others they do not make sense, or rather they may not think about certain things they should do while at the gym.  Like the guy ( or girl ) who comes to the gym to throw some heavy weight around, then leaves the huge plates on the machines, or the dumbells on the ground.. I mean  HELLO ! does your mom work here? and would she actually pick up after you? 
And what about the bench someone just got done using, and there are sweat marks running up and down the whole thing. Now that is just gross. I dont know about you, but i would rather not lay in someone elses  sweat. 
Many gyms give you a list of rules and regulations when you join, or the rules might be posted, but you would think most of these things are common sense. I am going to list a couple rules that should be used at gyms, not only for health reasons, but for common courteousy. 
Rack your weights
clean up your sweat
dont be a machine hog
dont interupt someones workout
dont grunt toooo loud :)
dont tell other people how to lift, ( unless they ask)
dont talk badly about trainers, or aerobics instructors ( everyone has been taught differntly, and unless you are perfect you have no room to talk )
dont be on your cell phone the whole time you are working out ( i mean really, are  you here to workout or gossip )
dont over flex in the mirrors  ( save that for your bathroom mirror :) )

These are really just a few that I could think of, If you have any pet peves at the gym, please let me know,, I would love to hear them.. We are all guilty of something, so make sure you do your best to clean up after yourself, and to be curteous to others.  cya at the gym !!
 

Things are going great, your workouts are improving, your eating is on key, then BOOM, Injury.  WHy? you say. I dont have time for this. Tings were going so well, now what do I do?  You dont want to quit, but you cant contiue in the way you are now. What should you do?
 The best thing to do is to find out the extent of the injury. Is it a pull, or strain, or sprain?  Then you can go from there. I know for those few determined people out there, nothing will keep them down. Especially if you are trying to accomplish something, or working toward a specific goal.  
 I have delt with this recently. My workouts have been awesome, up until the back of my leg started hurting. So I try getting through my workouts in the same way I was, and I realize that would not be the best thing to do.  I pray for my injury to heal quickly, and try my best to work around my pain.  Which means,,, no leg day,,, Now Im not really crying about that, but when it comes to my legs leaning out,, thats not gonna help.  But If I dont take time off for healing, im not gonna be able to push out what I could if I give myself time to completely heal. And I take a chance of hurting myself even more.  Not worth it. 
 So when injurys play a part in your workouts, I would give yourself plenty of repair time, You will be thankful you did when its all better.  Just dont sit on you butt, stay active, and motivatied. One or two weeks of rest will not set off your goals too much. Stay focused and determined to get back on track.
