Body warming before training

Body warming before training is an indispensable component of the training process. Each training session should commence with this step. Novices often disregard this step or perform it incorrectly. This can lead to injuries but also slows down progress. Training without proper body warming is less effective as the body and mind are not adequately prepared for the exertion.

Gradual Increase in Weight

Muscle growth is only possible when muscles are continuously given a stimulus to grow. If this stimulation is inadequate, the muscles will not be able to benefit from the training. The only way to compel muscles to grow is through a gradual increase in weight, which sets higher and higher demands for the muscles. Muscles are capable of rapid adaptation to efforts and volume, which causes them to stop growing. There are many methods of progression, such as increasing the weight, the number of sets or repetitions, shortening the rest time between sets, and introducing different speeds of exercise execution. Everything depends on the goals one wants to achieve.

Set and repetition counts in exercise

It is generally advised to carry out 3 to 5 sets of an exercise, which is deemed the best method for several reasons. In practice, this number of sets is sufficient to maximally engage muscle fibers for work. However, if the number of sets for each exercise is increased, the total amount can be too much and lead to fatigue and consequently to a decline in performance. Note that in the case of large muscle groups, such as the back or chest muscles, a higher number of sets can be utilized during one training unit. Remember also that small muscle groups are also activated during exercises for other body parts, such as biceps muscles that are involved during back training. To make the training effective, certain effects need to be achieved, such as hypertrophy, if the goal is muscle building, or increasing strength by engaging more muscle fibers in a single movement. This means that the number of repetitions, weight, and tempo need to be adjusted, which promotes the stimulation of muscle fibers and results in the weight needing to be chosen so that the set number of repetitions can be performed with correct technique.

Total range of motion

Scheduled strength exercises should be carried out with the total range of motion (with the exception of situations where a limited range is required). This means that each muscle must be stretched to the maximum extent and then shortened to full contraction. This is the only method that allows for influencing both the entire muscle and individual muscle fibers. Working with the total range of motion enhances overall efficiency and protects muscles from injuries such as tears or strains.

The caliber of muscle fiber contractions

Correctly conducted exercise results in the stimulation of muscle fibers, which is an outcome of strength training. To attain the best results, it is crucial to focus on maintaining the proper stance, tension, and movement control. Bear in mind that during exercise, not only primary muscles but also secondary muscles are engaged. During exercise, it is vital to sense and manage the tension in all engaged muscles, not to concentrate on lifting the maximum weight. The weight is simply a means to achieve the intended purpose.

An interval between sets

The implementation of an appropriate time interval between sets and exercises is a very important component of every training session. Both an interval that is too short, as well as one that is too long can negatively affect the intensity of the training. In the case of an interval that is too short, the muscles will not have enough time for recovery and rest, while in the case of an interval that is too long, the muscles will become relaxed and lose stimulation, which will prevent them from responding properly during training. Therefore, it is crucial to adjust the duration of the time interval between sets according to the current training, the type of exercises and the volume of the sets. In particular, during strength training, after transitioning to the working sets, a time interval that is too short can lead to a decrease in training intensity. This is caused by the fact that after the first minute of rest, the muscles regain about 70% of their strength, and after 3 minutes, this value approaches 100%. However, it is important not to forget that the main goal of hypertrophy-focused training is to maximize the engagement and partial damage of as many muscle fibers as possible. Therefore, it is so essential that the muscles do not have enough time to fully rest between sets.

Proper respiration

Respiration is an automatic process. However, many trainers and instructors are surprised when they hear the question: "How should I breathe during exercise?" This is not a strange question, as most people breathe incorrectly during physical exertion. During respiration, many muscles work, including the stabilization muscles (core) that help maintain posture during exercise. To breathe correctly, one should focus on diaphragmatic breathing (breathing into the diaphragm). The diaphragm is one of the stabilization muscles, and its contraction along with the entire core protects the internal organs and allows lifting of significantly more weight.

Regenerative reaction

Intensity denotes the level of tension at which muscles fulfil their tasks. The more work, the more intense the training will be. However, the greater the intensity, the longer the regeneration period required by the body for growth and rest. Overtraining may occur when muscles are subjected to work of such intensity and volume that they are unable to carry out their functions. Intense muscle contractions are associated with elaborate biochemical and mechanical processes.

Stretching of muscle fibers

Stretching is an integral part of training that is often neglected even by highly qualified athletes. Muscles, tendons, ligaments and joints are flexible, but they may lose their flexibility, which leads to restricted mobility. However, the opposite can also occur, they can stretch further, which increases the range of motion and activates a greater number of muscle fibers. Dynamic stretching before training allows for training under higher tension and increases safety during training if the exercises are performed technically correctly. Stretching muscles in the full range of motion causes the shortened muscles to stretch against their antagonists, which increases elasticity. However, it is not enough to stretch before training, it should also be done after training. Here, static stretching is a good choice, which accelerates the regeneration of muscles after performing strength exercises.
