Identical exercises can be performed using weights and on machines... But will they genuinely produce the same results? In this text, we will help you eliminate all your doubts!
Barbell versus training equipment – muscle activation
Barbell lifting necessitates a larger number of muscles for every movement because the athlete has to ensure their body stabilization. During training on exercise equipment, the equipment itself performs this work for humans. Strength training with weights strengthens the deep muscles that are responsible for position stabilization. Exercise equipment has an isolating character, superficial muscles are engaged in the work. A person who limits themselves to only exercise equipment training may skip training certain muscle parts, which can lead to injuries over time.
Functional capability
Exercise with barbells refines motion coordination. It necessitates the capacity to sustain balance. It more extensively mimics daily movements. Consequently, barbells permit muscle shaping in a natural manner. It's easier to hoist a specific weight on a machine than with a staff, thus free weight training amplifies technique.
The power
Equipment enables the lifting of heavier weights than an athlete can manage using a bar. It may seem that machines are more effective in developing strength. However, this is merely an illusion. Machines eliminate the requirement to balance the body with substantial loads. Consequently, in strength training, straps remain irreplaceable. This equipment is a key component of training programs for professional athletes.
Caloric expenditure during free weight exercises
Free weight exercises activate most muscle groups with each repetition and also necessitate maintaining balance. Owing to these two factors, the caloric expenditure during such a workout session is higher than during machine exercises.
It's all about protection and security
When it comes to protection and safety, machines have an advantage due to their specialization. During the performance of exercises on specialized equipment, the risk of leaving the barbells unsupervised is significantly lower, however, machines are advanced equipment intended for muscle isolation, which is not recommended for beginners. Machines do not require the same level of attention to technique as free weights, but long-term execution of isolation exercises can lead to a disproportion between individual muscle groups. Weight training has a significant advantage when it comes to body stabilization, which directly affects safety in the gym and during daily activities.
Methodology
The machine generally determines the right direction of motion. Therefore, it is difficult to perform the movement incorrectly technically. The devices often include instructions on how to train on them. During the device training, the support of a colleague is also not necessary. However, working with free weights requires more knowledge, so athletes who are interested in long-term strength development should learn the correct technique of handling a bar or dumbbells.
Hormonal control
Investigations have demonstrated that performing the same exercises on a machine or with free weights results in varying hormonal responses. Research has proven that training with barbells contributed to the release of 17% more testosterone in the body than training on a machine. This hormone holds paramount significance in the context of building muscle tissue.
Conditions of employment
The immediate cause of injuries in both free weight exercises and machine exercises is an inadequate execution technique. Other factors that contribute to an increased likelihood of injury are excessive weight or uncontrolled, excessively rapid movements.
Availability
Both devices and bars form part of the essential equipment in most gyms. For individuals desiring to work out at home, purchasing a bar as opposed to a device is a considerably more convenient option. Primarily, it occupies less space, secondly, it is significantly more affordable. A complete set of a bench + bars with weights amounts to no more than 500 zł. The cost of devices can range from several to even several thousand złoty, depending on the specifications.
