Mistakes to avoid when starting weight training
Everyone starts somewhere. And weight training, like any sport, has its pitfalls—classic mistakes that almost all beginners make, often without realizing it. The problem is that these errors slow down progress, increase the risk of injury, and, in the worst-case scenario, discourage people who could have made rapid progress with the right guidance.
At Society Sport Lonay, our fitness coaches in Morges see these mistakes every day in our weight training gym in Morges. In this article, they explain which ones to avoid—and, above all, how to correct them—so you can start your strength training on the right foot and see tangible results quickly.
Mistake #1 — Neglecting technique to lift heavier
This is the number one mistake beginners make at our gym in Lonay. The temptation to load as much weight as possible onto the bar is strong—especially when you see other members lifting impressive loads. But sacrificing technique just to impress others is a recipe for injury.
Poor technique on a squat, bench press or deadlift doesn't target the right muscles — and puts enormous strain on the joints, tendons and spine. As a result, you risk an injury that will leave you out for several weeks — and cause you to lose all your earnings.
The golden rule according to our certified coaches in Lonay: start light, master the technique, then gradually increase the loads. A perfect 40kg squat will do more for you than a wobbly 80kg squat — and will keep you healthy in the long run.
Mistake #2 — Not having a structured program
Arriving at our gym in Lonay without a program is like going on a trip without a GPS. You'll end up going around in circles—the same exercises, the same loads, the same stagnant results.
A structured strength training program defines precisely which muscles you work on which day, how many sets and repetitions you do, how you progress in weight week after week and how you integrate recovery periods. Without this structure, your progress quickly stops — even if you come regularly to our fitness club in Lonay.
That is exactly why our fitness coaches in Morges offer a fitness assessment and a personalized program to every new member as part of our personal coaching service. This way, from your very first week at our gym in Morges, you have a clear plan—and every session brings you tangibly closer to your goal.
Mistake #3 — Trying to work on everything at once
Many beginners want arms, abs, shoulders, legs, and a V-shaped back—all at once. That’s understandable. But in bodybuilding, trying to work everything simultaneously often leads to not really working anything at all.
In fact, each muscle group needs 48 to 72 hours to recover after an intense session. If you use the same muscles every day, they don't have time to rebuild — and they don't progress. In addition, a busy schedule quickly discourages beginners due to exhaustion and lack of visible results.
Our certified coaches in Lonay recommend starting with a full body program 3 times a week — exactly the format of our full body course in our fitness room in Lonay. This format works the whole body in a balanced way, allows sufficient recovery between sessions and produces visible results quickly for beginners.
Mistake #4 — Ignoring recovery days
Following on from the previous mistake, many beginners think that the more they train, the faster they progress. That is incorrect—in fact, the exact opposite happens.
As we explain in our article on post-workout recovery, your muscles don't progress during training — they progress during recovery. In other words, rest days aren't wasted days — they're days when your body is actively building the muscle you stimulated at the gym in Lonay.
Our sports coaches in Morges recommend at least one day of rest between each intense bodybuilding session, especially at the start of practice. “Active rest” days — like a yoga or pilates class in our gym in Lonay — are perfect for recovering without being inactive.
Mistake No. 5 — Neglecting the warm-up
Warm-ups are often viewed as a waste of time by beginners eager to start their workout at our gym in Lonay. It is a costly mistake.
A 10-minute warm-up is enough to increase muscle temperature, improve joint lubrication, activate the nervous system and significantly reduce the risk of injury. Without warming up, your cold muscles and stiff joints are much more vulnerable to strains, strains and sprains.
Our certified coaches in Lonay recommend a 5-minute general warm-up—on a stationary bike, treadmill, or rowing machine—followed by a specific warm-up involving light movements that mimic the exercises in the workout. This ensures your body is ready to perform from the very first repetition, allowing you to train more effectively throughout the entire session.
Mistake #6 — Not eating enough protein
As we saw in our article on sports nutrition, protein is the building block of your muscles. Without sufficient protein intake, your body simply cannot rebuild the muscle fibers damaged during workouts at our weight training gym in Morges.
Many bodybuilding beginners train hard but eat little protein — and wonder why they're not progressing. The answer is simple: you stimulated the muscle, but you didn't provide it with the material to rebuild itself stronger.
The general recommendation of our sports coaches in Morges for a beginner in bodybuilding: aim for between 1.6 and 2 grams of protein per kilo of body weight per day. According to the International Society of Sports Nutrition, this intake is sufficient to maximize protein synthesis and muscle mass gain in the vast majority of amateur athletes.
Good sources of protein to include in your diet:
- Chicken or turkey breast
- Whole eggs
- Fish — salmon, tuna, cod
- Greek yogurt
- Legumes — lentils, chickpeas
- Whey protein if necessary
Mistake #7 — Comparing your progress to that of others
In a Lonay gym, it's tempting to compare yourself to other members — especially those who lift impressive weights or have a figure you admire. But this comparison is not only unnecessary — it is also discouraging and counterproductive.
Every body is different. Genetics, sports history, diet, sleep and dozens of other factors influence the speed of progression of each individual. The person next to you lifting 100kg may have been training for 5 years. Comparing your week 2 to year 5 is condemning yourself to disappointment.
The only meaningful comparison is you against yourself — last week, last month, last year. This is why our certified coaches in our fitness club in Lonay note your loads and your progress from the start - to show you concretely how far you are progressing, even when you don't feel it.
Mistake #8 — Giving up too soon
This is arguably the biggest mistake of all. Strength training takes time—and the first visible results generally appear after 6 to 8 weeks of regular practice. Many beginners give up within the first 3 to 4 weeks, just before the results start to show.
In reality, even if you don't yet see the changes in the mirror, your body adapts from the first session — your nervous system becomes more efficient, your tendons strengthen and your muscles learn the movements. These invisible adaptations are the foundation for your future visible results.
The key is consistency. And that's exactly why the group classes at our gym in Lonay are a great entry point for bodybuilding beginners — they create structure, community and external motivation that help you get through those difficult first weeks until you see the first results.
