Is your fitness business suffering because of the mistakes you’re making?

Trying to lose weight and stay active is hard enough, but seeing your progress stalled by your trainer is even more discouraging. Want to avoid this?

Fitness trainers are people too, and we all make mistakes. Here are the eight most common mistakes for fitness trainers and how to avoid them.

By procrastinating and not preparing for workouts and meal planning, trainers could be working against their clients’ progress. That being said, fitness trainers can avoid this mistake by taking the time to set goals and be proactive.

By taking the time to do research and creating fitness programs based on the goals and capabilities of their clients, trainers can give clients the best results.

2. Not Setting Boundaries

Boundaries are important to have in place when it comes to clients. It allows both parties to have clear expectations and protect the relationship between the trainer and the client. It is important to have a contract and schedule an initial meeting with clients to discuss expectations and rules.

3. Keeping Up With Trends

One of the most common mistakes for fitness trainers is not staying up to date on the latest developments. Not only will this limit your abilities as a trainer, but your clients will also be missing out on the best possible information.

Make use of personal networks, podcasts, websites, and conversations with experts. Read referenced materials and stretch your learning by attending conferences and seminars.

4. Poor Nutrition Practices

Nutrition plays a vital role in any fitness program, and a trainer is responsible for providing their clients with the best and most informed advice. Unfortunately, not all trainers have strong nutrition expertise, which can lead to giving outdated and even potentially dangerous advice.

Stay up to date with the most current and relevant nutrition practices and attend workshops. Start by getting a Master Level Personal Trainer Certification and/or consult with a nutrition specialist when necessary. More information can be found here.

5. Poor Technique & Ergonomics

Poor technique or improper form can cause an individual to be at risk for injury, and image or posture issues. A trainer should ensure that the instruction for each exercise is correct and that the participant is executing the movement correctly and safely.

It is also necessary for a trainer to be knowledgeable in ergonomics and adjust the equipment based on the needs and goals of the participant.

6. Ignoring Signs of Mental Fatigue

Mental fatigue can seriously impact a person’s ability to push themselves safely in their training session. To avoid this, fitness trainers need to pay close attention to their clients, especially if they seem to be struggling more due to mental exhaustion.

They may appear unmotivated and tired and make comments about not being able to push themselves during training client sessions. Fitness trainers must intervene and take a break from intense training sessions.

7. Promising Results that are Unattainable

There are a lot of so-called “fitness trainers” out there who promise amazing results that are simply unattainable. This is one of the biggest mistakes that trainers can make, and it’s one that can easily be avoided.

When you’re making promises to your clients, make sure that they are realistic and achievable. Don’t set the bar too high or make claims that you can’t possibly deliver on. Be honest with your clients and let them know what they can expect from working with you.

If you do make promises that you can’t keep, you’ll not only disappoint your clients, but you’ll also damage your own credibility as a trainer. So always make sure that you can deliver on what you promise!

8. Not Incorporating Variety

One of the most common mistakes that fitness trainers make is not incorporating enough variety into their workout routines. This can lead to boredom and eventually, discouragement, when people don’t see the results they want.

To avoid this mistake, it’s important to keep your workouts interesting by mixing up the exercises you do, the order in which you do them, and the amount of time you spend on each activity. For example, if you typically do 30 minutes of cardio followed by 30 minutes of strength training, try doing 20 minutes of cardio followed by 40 minutes of strength training instead. Or, if you usually do three sets of 10 reps on each weight machine at the gym, try doing four sets of eight reps.

Incorporating variety doesn’t just mean changing up your workout routine from time to time; it also means making sure that you’re working all major muscle groups equally. This means that you shouldn’t always do the same exercises day after day or week after week. For instance, if you typically do chest presses on Monday and Wednesday, make sure to do pull-ups or rows on Tuesday and Thursday so that your back muscles get a workout too.
