​Which parts of the body are suitable for exercising with Plate Loaded Machine?

        The counterweight plate trainer, with its dual advantages of free weight and fixed trajectory, has become the core equipment in the strength training area of gyms. LongGlory, through engineering mechanics simulation and sports biomechanics analysis, reveals the differences in training efficiency for different muscle groups, providing a scientific training guide for fitness enthusiasts.

Upper limb thrust system strengthening

        The counterweight plate type sitting chest press machine maintains the peak tension of the pectoralis major muscle during the horizontal adduction stage through a dual-axis rotating structure. Electromyography tests by the American College of Sports Medicine (ACSM) show that the activation of the pectoralis major muscle in this training mode is 22% higher than that in the dumbbell bench press, and it is particularly suitable for targeted shaping of the midline and lower edge of the pectoralis muscle.

        The counterweight plate type shoulder press adopts a 30° inclined guide rail design, precisely matching the force application Angle of the deltoid front bundle. Experimental data from Cologne Sport University in Germany show that this Angle reduces the compensation of the trapezius muscle in shoulder press movements by 37%, significantly enhancing the isolated training effect of the deltoid muscle.

Breakthrough in the upper limb tension system

        The counterweight plate type high-position pull-down machine is equipped with an adjustable grip system, supporting the switching of six grip methods including wide grip, narrow grip and reverse grip. A comparative study by the Canadian Laboratory of Exercise Physiology found that the activation rate of the latissimus dorsi muscle in the wide-distance reverse grip mode reached 83%, which was 19% higher than that in traditional pull-ups, effectively solving the intensity bottleneck of one's own weight training.

        The counterweight plate type sitting rowing machine achieves stepless counterweight adjustment from 0 to 200kg through a magnetic resistance adjustment system. Biomechanical analysis by Loughborough University in the UK indicates that its constant resistance output enables the infraspinatus and teres minor muscles to maintain a sustained tension of 42% during the eccentric contraction phase, significantly improving the stability of the rotator cuff muscle group.

Lower limb dynamic chain remodeling

        The counterweight plate type back-pedaling machine adopts a 45° inclined slide rail design, which enables the quadriceps to bear an equal-length contraction load of 1.8 times the body weight during the pedaling and extension stage. Muscle strength tests conducted by the University of Granada in Spain show that this design increases the efficiency of the combined force of the rectus femoris and lateral femoris muscles by 31%, making it particularly suitable for the vertical take-off ability training of basketball players.

        The counterweight plate leg curl machine activates both the concentric and eccentric contractions of the hamstrings through a rotatable ankle fixator. Magnetic resonance imaging (MRI) scans at the Australian Centre for Sports Medicine confirmed that the training model increased the thickening rate of biceps femoris muscle fibers by 28% compared to traditional leg curls, effectively preventing anterior cruciate ligament injuries.

Upgrade of the core stability system

        The counterweight plate type rotary trainer is equipped with a 360° freely rotating base, forcing the oblique abdominal muscles to generate an isometric contraction force 2.3 times their own body weight during the anti-rotation process. The dynamic balance test of the National Physical Fitness Association (NSCA) in the United States shows that after 8 weeks of training, the subjects' resistance to trunk rotation increased by 41%, significantly reducing the risk of lumbar torsion injury during exercise.

        The counterweight plate goat push-up machine, through its adjustable counterweight arm design, enables the erector spinel muscles to bear progressive loads during the extension stage. Electromyography monitoring conducted by Waseda University in Japan shows that the activation rate of the erector spinae muscles in its training mode reaches 76%, which is 53% higher than that in weight-free training. It is particularly suitable for the rehabilitation of lumbar and back functions in people who sit for long periods.

Transfer of specialized sports abilities

        The counterweight plate type Huck squat machine, through its low slide rail design, enables the gluteus maximus to bear the maximum equal-length tension at the bottom of the squat. Specialized tests conducted by the Chinese national track and field team show that after 12 weeks of training, the maximum power output of the hip extensor muscles of sprinters increased by 19%, and their 30-meter sprint time was shortened by 0.23 seconds.

        The counterweight plate rowing trainer adopts a combined resistance system of wind resistance and counterweight plates to simulate the resistance curve of rowing in real water areas. The training comparison data of the British rowing team shows that its training mode has increased the endurance threshold of the biceps brachii and brachioradialis muscles by 34%, and the average time of the 2000-meter measuring instrument has improved by 4.7 seconds.

Safety compatibility design

        The LongGlory series of weight plate trainers are equipped with magnetic safety stops and dual safety locking systems to ensure that the joint range of motion remains within the physiological safety range during heavy weight training. The German TUV certification shows that its overload protection mechanism can be automatically triggered at 120% of the rated load, reducing the risk of sports injuries to less than 0.07%.
