The Most Common Gym Mistakes to Avoid

13th Dec 19

When you go to the gym, it’s difficult to do anything “badly”. But whatever reason you have for going, it has a world of benefits to offer you, and all of them have a huge impact on your life. It’s generally just a great thing to do for yourself. Like everything in life, though, there are some things that you should still avoid when you go. That’s when you need to look out for common gym mistakes.

It’s easy to do something new and get it wrong or even get stuck in bad habits. However, getting out of them is one of the best things you can do, and the first step to doing that is to know the biggest mistakes you can make in the gym and the best ways to stop them.

We’ve put together a list of 6 of the most common gym mistakes so that you don’t make them yourself. So make sure you take note and heed our warning to maximise your progress and minimise injury.

1. Lifting Too Heavy

First, up is lifting too heavy. Everyone who has ever been to the gym is guilty of it. Whether you’re trying to look good, you don’t know your own strength, or your technique is off; it’s something that’s just too easy to do. Despite that, lifting too heavy is still one of the biggest gym mistakes you can make.

It’s one of the easiest ways to develop an injury, both short and long-term, and it will stifle your progress too. We know it sounds hard to believe since more weight is usually more progress in most people’s minds, but it’s just not the case. Like we said in our advice for people new to weightlifting, form is ALWAYS better than weight.

2. Misusing Equipment

Another hugely common gym mistake to make is misusing equipment. We’ve said it before, and we’ll say it again. Misusing equipment is just straight-up dangerous. You can do serious damage, either from an actual incident with the equipment directly or the equipment injuring you due to how it’s supposed to move.

Some of the most common ways you’ll see this is with things like locking knees on a leg press, pushing with your legs on lower back machines, and even using cables in ‘inventive’ ways. You’d be surprised.

3. Using Dangerous Exercises

As well as different machines causing trouble in gyms, choosing the wrong exercises or doing notorious exercises wrong can have a hugely detrimental impact on you too. There are some exercises where you really need to know your stuff to try them, and they can all do serious damage if you don’t.

Some simple exercises like deadlifts have the potential to do real damage if you bend your back, for example, despite it being one of the best exercises there are. On top of that, you have other more general exercises, like dips and upright rows, where it’s too easy to overextend and injure your shoulders when you think you’re getting a better contraction. It’s all easily done, and it’s all dangerous.

4. Mirror Training

This one is more of a long-term issue that people seem to have in the gym without even realising it, and it does make sense when you think about it. It’s called mirror training.

Mirror training is when you exercise the muscles you personally can see in the mirror for the sole purpose of looking bigger. The typical examples are just training the chest, arms and abs rather than the back and legs. This is what people think looks the best, but it just leads to severe training imbalances and often dangerous overtraining. So train everywhere if you’re going to do it!

5. Overtraining

Another logical place to look after mirror training is overtraining in general. Overtraining is one of the easiest ways to halt and even reverse your progress if you don’t injure yourself before that happens. It is just one of the worst things you can do and can have massive repercussions.

Your body needs time to rest after exercise and recover from the stress you’ve put on it. That’s when all the changes you’re trying to make happen anyway. Training every day means more wear and tear and no recovery. It will result in an injury, and it’s seriously bad news.

6. Don’t Rep Too Fast

The final gym mistake we’ll look at is from repping too fast since it’s another one that just seems natural to do. It’s not quite as bad as a lot of the other exercises on the list, but if it gets the better of you, you’ll still be in a lot of trouble.

Repping too fast feels like the exercise is easier, and you can do more before you get tired. That’s a given. The reason, though, is you lose form, reduce the time under tension, and build momentum. All of those are dangerous, and you’re way more likely to hurt yourself than you were before. So take it slow or drop the weight. Either way, slow it down.

These are easy mistakes to make in the gym, and many are even easier if you’re working out at home too. Always remember that form is everything; take your time, and do your homework.
