7 Common Gym Mistakes

From skipping the warm-up to training without a programme: seven mistakes that slow progress, and their fixes.

If you do not feel progress in the gym, the problem is often not the amount of work but the way you work. We have compiled seven common mistakes our coaches see every day, and their fixes.

1. Skipping the warm-up

Lifting weights without preparing muscles and joints raises the risk of injury. 5–8 minutes of light cardio and mobility, followed by a warm-up set with light weights, is enough.

2. Chasing weight rather than technique

Ego-lifting is the riskiest behaviour for the spine and joints. If you cannot do the movement under control and through a full range, the weight is too much. Ask a coach for a technique check.

3. Training without a programme

Wondering "what shall I do" every day slows progress. A written programme (movement, sets, reps, weight) and a log make progressive loading possible.

4. Neglecting rest

Muscles grow not during training but while resting. Do not tire the same muscle group on consecutive days; aim for at least one full rest day a week and 7–9 hours of sleep.

5. Only cardio or only weights

A balanced programme includes both. Strength training preserves muscle and bone density, while cardio improves cardiovascular health.

6. Not caring about nutrition

Most of the effect of training is decided in the kitchen. Enough protein, complex carbohydrate and water are needed. Overly restrictive diets lead to muscle loss.

7. Comparing yourself with others

Everyone in the gym started from a different point. Measure your own progress: are you lifting more than last month, running longer or sleeping better?

What to do?

In our clubs we offer new members a free introduction with a coach and a starter programme. If you get stuck, a personal training session can review your technique and programme. If you feel pain or discomfort, stop training and consult a doctor.

Bonus: keep a record

Keeping a training log solves most of the seven mistakes above on its own. In our app you can record the weight, sets and reps of every workout and compare with last week. When you hit a plateau, seeing when it began and what you changed points to a solution. A monthly review with your coach keeps your goal up to date.
