Be Open About What You Really Want
If you want a nicer butt, own it. There's nothing wrong with having superficial goals. Friends, instructors, and trainers are only going to be able to support you if you tell them what you're actually after. Focusing on things that aren't important to you is a sure way to get frustrated.
Remember That Money Does Matter
Anyone who tells you to splurge on an expensive gym membership has probably never set foot in a gym. Spending more won't make you go more, it will make you want to quit and get a full refund ASAP. Take the money you save going somewhere affordable and treat yo self to some nice workout supplements instead.
Embrace the Awkward "Getting to Know You" Phase
Walking into a gym for the first time is nerve-racking. Having a trainer or a friend coaching you will make it easier, but it's still important to explore on your own and make mistakes. Once you're comfortable being at the gym alone, you can start taking things to the next level.
Make a Serious Commitment
You must vow that this is going to be a permanent lifestyle change. It's going to take some time and lots of trial and error, but know that eventually you will get where you want to be. Commit to learning more about how your body works, and what you can do to improve it.
Don't Be Afraid To Ask For Advice
Always be willing to ask others for help when things get complicated. Chances are that gym rat you find so intimidating is actually a really nice person who loves to talk fitness. If they do bark at you, they're probably on steroids and you should run for your life.
Find Ways to Spice Up Your Workout
When you find yourself zoning out five minutes into a workout, it's probably time to mix things up. As with any relationship, the internet is your source for interesting and sometimes shocking inspiration. Apparently gummy bears are great as a post workout snack. Yum!
Make It About More than Just Your Body
Make the gym your safe place. When you have a bad day at work, know you can go to the gym and blow off some steam. When your boyfriend breaks up with you, know you can go the the gym and remind yourself how strong you are. When a pigeon poops on your head, know you can go to the gym and take a shower.
Stop Comparing Yourself to Others
It's a love-hate relationship with the eye candy at your gym. You love having something nice to look at, but hate feeling inadequate in comparison. Stop doubting yourself so much and remember that the most important thing is to not get caught staring!
Know When It's Time to Move On
Sometimes it isn't you, it's the gym. If the staff is always rude, if the equipment is falling apart, or if the parking lot is always full then you should probably consider seeing what else is out there. Parting is such sweet sorrow until you realize that the gym across the street has free pizza.
