On Cadillac fitness equipment (Cadillac bed), targeted exercises for all muscle groups can be achieved through the following spring combinations and motion designs:

1、 Core muscle group strengthening combination
Roll Down lever (wooden handle) and light spring
Action: Lie in a supine position, slowly roll the body with both hands holding the pole, and stretch the spine section by section.
Effect: Activate deep abdominal muscles (such as transversus abdominis), improve core stability, while stretching back muscles and relieving back tension caused by prolonged sitting.
Tower low support point+medium weight spring
Action: Kneel or sit, push the tower pole with both hands towards the far end, and maintain the stability of the torso.
Effect: Strengthen rectus abdominis and oblique abdominis muscles, enhance trunk anti rotation ability, suitable for advanced core training.
2、 Combination of upper limb and back muscle groups
Tower high support point+light spring (suspension training)
Action: Grasp the tower pole with both hands and hang it, with the body in a horizontal straight line, and perform shoulder adduction or abduction.
Effect: Exercise the deltoid, latissimus dorsi, and small upper back muscles to improve round shoulders and hunchback.
Swing frame+medium weight spring
Action: Lie prone, hold the swing frame with both hands, and perform the “rowing” action through spring resistance.
Effect: Strengthen the middle back (middle and lower trapezius muscle, rhombus muscle) and biceps brachii muscle, and enhance the back line.
3、 Lower limb muscle group strengthening combination
Bed slide rail+heavy spring (leg push pedal)
Action: Lie down, step on the slide with both feet, and use spring resistance to push and push the legs.
Effect: Targeting the quadriceps, gluteus maximus, and hamstring muscles, it shapes tight leg lines and enhances lower limb strength.
Swing frame+light spring (single leg suspension training)
Action: Hang one leg on the swing frame, maintain body balance, and perform hip joint abduction or adduction.
Effect: Activate the gluteus medius, gluteus medius, and medial thigh muscles to improve pelvic stability.
4、 Whole body comprehensive training combination
Tower center pivot point+multiple spring combination (dynamic balance training)
Action: Standing position, hold the tower pole with both hands, and use spring resistance to stand on one leg or dynamically balance and move.
Effect: Coordinate the whole body muscles (core, lower limbs, upper limbs) to work together, improve body control and coordination.
Swing frame+spring system (hanging inverted)
Action: With the assistance of the coach, use the swing frame and spring to complete the inverted movement.
Effect: Stretching the spine comprehensively, strengthening the shoulders, back, and core muscle groups, while improving blood circulation.
5、 Principles of Spring Selection and Training
Weight classification: Light springs (grades 1-2) are suitable for beginners or flexibility training, medium springs (grades 3-4) are used for strength and coordination training, and heavy springs (grades 5 and above) are suitable for advanced trainers.
Action matching: Select springs based on training objectives, such as prioritizing light to medium springs for shaping and medium to heavy springs for muscle building.
Safety reminder: For the first use, adjust the spring resistance under the guidance of a coach to avoid muscle strain caused by excessive load.
