Beginner or advance bodybuilding expert, we can all make mistakes when it's gym time. Some of them can be a lack of knowledge when it comes to the lifting department, but others are commonly stupid and can be fix just by paying a bit more attention. In this first edition of the top gym mistakes you can do, we will see 10 of them that you might just see yourself doing everyday in and out the gym. 1. Not paying attention to your diet Depending on your goals, eating not enough ou eating the wrong food will not only stop you from making the right gains, but it can surely provoke the opposite and make you lose what you worked so hard for.... 2. Avoiding the "Big lifts" To optimize your workout, everybody should have Big lifts in their workout plan like deadlifts, squats, bench presses, military presses and power cleans. They might seem scary for some people, but these exercises are a true fastpass for gains in strength and size. 3. Skipping leg day Ok, we know you do it, it happens to everyone to have a day where you don't feel like training your lower body, but it is in fact THE most important day of your whole training schedule. Leg day is known to boost your metabolism, what it means for you, it's going to boost your mass gains and burn faster that after Christmas fat you've been adding up for years now. For last, i'm sure you don't want to be that guy at the gym that everybody calls "chicken legs". 4. Poor form Very important, make sure you have the proper form when doing an exercise, if you're not sure you are doing it right or not, don't be afraid to ask a trainer at your gym or someone that has more experience than you do, injuries happen fast and hit hard sometimes, which will slow your way to aestheticism. 5. Going too heavy When you enter the gym, they don't mention it on the door unfortunately, you have to leave your ego on the door steps. Don't worry you can get it back after your workout, but it's important to understand that lifting heavy is good for mass and strengh gains, but lifting too heavy for you will not only make you look like a douchebag, it can cause injuries and slow down your gains. 6. Texting in-between sets Keeping your phone on you at the gym is not prohibited, but if you start texting the girlfriend/boyfriend in-between each and every set you might find yourself having an addiction for texting, which is a sign of mental illness. If so please see a doctor immediately. Seriously, always having your phone in your hands will make you lose the concentration you need to lift your next personal best. 7. Not Re-racking the weights Simple laziness, please re-rack your weights when you are done with them, if you are strong enough to push them up in the air, you are strong enough to put them back in their place. Be respectful to others. 8. Late night pre-workout shake This right here is a beginner's mistake, don't take a pre-workout shake if you train before going to sleep, I tell you you're going to have a bad time. Pre-workout supplements have ingredients like sugar and caffeine, that will ultimately lead to insomnia. 9. Forgetting to wash your shaker For sure happened to you before, don't let your protein shaker grow a stinky monster inside, wash it right away when you are done drinking. 10. Leaving your gym bag in the car on a hot summer day If you leave your gym bag in the car on a hot sunny day, considering that bacteria will multiply, leaving your shirt and shorts with a fresh breeze coming right from hell. **EXTRA: Forgetting your phone at home so you can't send snapchats to the @justsquad community ;) Sources photos: W_minshull Richard Foster hikingartist aryaziai Noodles and Beef
