fitness equipment;gym equipment;body building; Measure(L*W*H)**0***8***0(CM) Product name: recumbent barbells practice chair Type: LK****5 Origin: guangzhou baiyun district Feature Main body color: silver Cushion color: scarlet Main body weight: *4 kg The product specification: **0 * **8 * **0 (CM) Packing specification: **5 * **3 * **5 (CM) Cushion material: renewable sponge + PU leather, flexibility is good, not easy deformation. The frame had material: use 2.5 mm steel building, the strong and durable. Rust removal process: adopt international advanced blast cleaned process, good toughness, corrosion resistance, high adhesion. Knob: the material alloy die casting and become, wear resistance is not easy to corrosion, never rust Surface spraying: use high strength flash silver secondary spray light oil strengthen, is not easy to change color. Barbells piece: the barbell piece using iron manufacturing, the surface using plastic bags processing, reduce the friction placed process noise. Barbells hoop: stainless steel building, the gripping the barbell rod surface, and can effectively prevent the barbell slip out of the barbell rod ends. Plastic accessories: using high quality materials to independent open mold design, there is the company LOGO marking. Barbells bar: the barbell stem use full stainless steel building, the steel rod overall well-balanced, toughness, and strength, have prevent slippery surface grain, prevent the movement process poles Unique feature The product USES the high quality steel products pure manual build, luxuriant appearance, smooth lines, the framework accord with human body engineering principle, the exercise process more comfortable, exercise the effect is remarkable. Unique double powder paint program make sport of having a car frame high temperament, and the treatment of the metal frame not easily refined cottony friction and peeling paint. Cushion: make the activists were always in in comfortable soft mattress protection, prevent the sports injury in at the same time strengthening the support to the human body. Instructions A. Recumbent may nominate Supine on the bench, and keep the hip touch stool surface, two feet lie flat on the ground, both hands distance than shoulder width, the forehand grip the barbell: - -inspiratory, make the barbell slow drop to the chest - -nominate barbells, make the action when expiratory Action change 1. Hold out a bosom increase nominate weight, can make the chest big muscle effectively exercise but do be careful when this action, prevent back injury 2. When are the barbell in their sides elbow, can make the deltoid muscle and get the key front exercise 3. Transform through hold distance - -hold narrow from strengthening chest big muscle of the medial exercise - -wide grip from the chest big muscle strengthening the exercise 4. To drop the barbell - -the next chest (near the thoracic inferior) can exercise chest big muscle of the lower - -in the chest can exercise chest big muscle central - -on the chest (near the neck) can exercise chest at the upper part of the big muscle 5. If the waist has a problem, or want to strengthen the chest big muscle of exercise, can carry feet bended leg abdomen to the top B. Narrow from recumbent may nominate grip Supine on the bench, the buttocks to face stool, double foot lie flat on the ground, the forehand grip barbells, according to the flexibility of the wrist, make hands in ****5 cm distance in between - -inspiratory, make the barbell slow drop to the chest, the elbow outreach - -nominate barbells, finish when expiratory Exercise place Recumbent may nominate mainly train pectorals, followed by triceps muscle, deltoid muscle front, former saw muscle and beak humerus muscle, etc From the recumbent may nominate narrow main exercise chest big muscle and triceps muscle, keep the elbow adduction, can strengthen the front of the deltoid muscle training Equipment maintenance A. Fitness equipment moving parts of the movement is designed between the rotation axes general 0.**1 ~ 0.**2 times the diameter size too small gap in the sports generate heat easily when jammed, large clearance and easy to produce the vibration, damaged parts in fitness equipment maintenance should check the moving parts movement clearance, for a long time or use use higher frequencies and produce big sports clearance, should be replaced immediately relevant parts, or inform the supplier B. Static equipment is a big part of the way of the component connection due to welding equipment in use process by all kinds of external force role, welding place may produce welding cracks, equipment maintenance staff and users often should pay attention to the spot welding, crack found to inform relevant personnel take measures to ensure the safety of the equipment use C. Equipment parts fittings in stress deformation when equipment would by external disappears, the equipment the deformation ceases, the deformation called elastic deformation and, by external equipment disappears, the equipment the deformation not disappeared, the deformation is beyond the scope of the elastic deformation of equipment, maintenance personnel should discover in time this kind of situation and notify the relevant personnel, exchange or the whole equipment parts ************************************************************************************************************************************************-
