The six most common gym training mistakes

The bar is loaded, the sessions are logged and the results still are not coming. Six training mistakes account for most of it, and every one of them is avoidable. Everyone makes mistakes and most people learn from them, but there is no reason to repeat every clumsy error personally before getting stronger. Learning from other people, from published research and from the practical knowledge of coaches is a considerably shorter route. Below are the six most common training mistakes on a gym floor. For an operator or a coach they are also a checklist: most of them are easier to avoid in a room that is properly equipped and properly supervised.

• Technique is everything
• Starting too hard invites injury

Mistake 1: no warm up specific to the session

This is the most common of all. The whole body is warmed up, body temperature rises, and the member goes straight into intense work. If the planned session reaches a submaximal load, or if the repetition count is high enough that the overload demands real effort and the muscles start burning, run two or three sets first with a lighter load but the same movement biomechanics. The same result can be reached by starting with a lighter weight and adding to it on every set until the working load is reached. This alone avoids a large share of the injuries and joint overloads that appear in the first heavy sets.

Mistake 2: no tempo on the exercise

Setting a tempo gives control over both phases of the contraction, concentric and eccentric. The concentric phase, also called the positive phase, is the one in which the muscle shortens and its attachments come closer together, as in a dumbbell curl for the biceps. The eccentric phase, also called the negative, is the one in which the muscle lengthens and its attachments move apart, as in lowering the dumbbell. Keeping a deliberate balance between the two makes sure the muscle is fully engaged, which is what drives growth.

Instead of moving the weight without thinking about it, follow the tempo written into the programme. It is usually written as 1-0-1-0, where the first and third figures are the eccentric and concentric phases and the remaining values are the pauses between phases. In practice the eccentric phase is often deliberately lengthened while the concentric is kept as short as possible. Whichever ratio is chosen, it needs to be a choice rather than an accident. Equipment matters here too: a machine with a smooth, consistent resistance curve makes a controlled eccentric possible, while a mechanical unit that jerks under load does not. This is one of the practical arguments for fitting a floor with professional strength training machines rather than lighter equipment.

Mistake 3: never changing the training cycle

Running the same exercises for more than eight weeks lets the muscle adapt to them, and progress flattens out. Change the training plan every four to six weeks. That does not mean rebuilding it: change the training method, the angle of the bench, the repetition count, the tempo, or swap the barbell for dumbbells. Muscles adapt to a specific pattern of work, so give them a new stimulus they are not prepared for and the results follow. A varied floor makes this easy, which is the practical reason a club needs benches at several angles, free weights and machines rather than one of each.

Mistake 4: skipping the last part of the session

A few simple things done at the end of a session speed up recovery, protect against injury and preserve range of motion at the joints. Here is what to add and what to expect from it:

• Myofascial release – a foam roller after training is always a good idea. Rolling the muscles that were worked increases blood flow through the tissue, which brings in the substrates recovery needs and helps clear metabolic waste. A rack of rollers costs very little and is among the most used fitness accessories in any club.
• Easy cardio – a few minutes of low intensity work on a bike or a treadmill after an intense strength session brings heart rate and breathing back down gradually rather than abruptly, and keeps blood moving through the muscles that were just loaded. It costs nothing but the machine time, which is one more reason for a cardio zone sized for more than peak hour running.
• Static stretching – best when session intensity was low and muscle damage minor. It maintains the flexibility of muscles and tendons, which in turn supports a good range of motion at the joints.

Mistake 5: paying no attention to technique

There are two complementary ways to build good technique, and they work together. First, learn the exercise in theory: look at the correct structure of the movement, meaning how the body has to be arranged for the technique to be right. Then find out which muscles should be under tension during that exercise, so you know which sensations are the ones you want and which ones signal that something has gone wrong.

Second, use the mirrors. There is no reason to feel self conscious about them, that is what they are for, and not for checking your physique between sets. Mirrors usually show the body from the side as well as the front, so technique can be checked on both planes at once. This is why mirror runs are part of the fit out of any serious training room rather than an afterthought.

Most important of all: do not hesitate to ask the instructors and coaches on the floor. Written material is a good source of theory, but acquiring correct technique usually requires someone watching the muscles work in real time and correcting what a text cannot.

Mistake 6: skipping the preparation period

Anyone coming back after a break, or starting for the first time, should plan a two to four week block to prepare muscles and tendons for harder work. That preparation phase covers every part of the body, with two to three sets per muscle group, twelve to twenty repetitions per set, at forty to fifty per cent of maximum weight. Only after that block does the real training plan begin. For a club, this is worth building into the induction: members who are eased in during their first month stay longer and get injured less.

Frequently asked questions

How often should a training plan change?

Every four to six weeks. Beyond eight weeks on the same exercises, adaptation flattens the results out. Changing method, angle, repetition count or tempo is usually enough.

What does a tempo like 1-0-1-0 mean?

The first and third figures are the eccentric and concentric phases in seconds, the other two are the pauses between them. Lengthening the eccentric while keeping the concentric short is a common variation.

Is a warm up not enough on its own?

A general warm up raises body temperature but does not prepare the specific movement. Two or three lighter sets with the same biomechanics as the working sets do that, and that is where most first set injuries are avoided.
