What does a push-up bar do?

1. The function of the push-up bar

(1) Enhance training effect

Increase the range of motion: Compared with directly touching the ground with the palms, using a push-up bar can increase the depth of the body's sinking by 20-30%, allowing the chest muscles to be stretched more fully.
Activate more muscle groups: Triceps participation increased by 15%, and the activation rate of upper chest muscle fibers increased by 22%

(2) Joint protection

Reduce wrist joint pressure by 40%: By maintaining a neutral grip, avoid 90-degree folding
Reduce elbow joint shear force: The rotating design can automatically adjust to the optimal angle

(3) Advanced training expansion

Can perform 360° rotation training to strengthen core stability
Support a variety of variations (such as offset push-ups, explosive push-ups)

2.Precautions for using a push-up bar

(1) Necessary inspection before use

Stability test:
Hold the push-up bar with both hands and apply 50% of your body weight to check whether the non-slip base is displaced (it is recommended to use on wooden floors/yoga mats)
The rotating push-up bar needs to be tested for bearing smoothness (no jamming or abnormal noise)
Material and load-bearing capacity:
The aluminum alloy bar body must have a load-bearing capacity of ≥150kg (thicker models are recommended for heavier weights)
The silicone grip has no aging cracks (friction coefficient μ＞0.8 to prevent slipping due to hand sweat)

(2)Standard movement essentials

Key Points	Correct Method	Incorrect Demonstration
Wrist Position	Maintain neutral position (in line with arms)	Excessive wrist dorsiflexion (can easily lead to tenosynovitis)
Elbow Angle	45-60° angle relative to body	Elbows abducted 90° (increases stress on shoulders)
Core Control	Brace the abdomen and tilt the pelvis posteriorly (avoid slumping)	Lower Back Slump (compensatory lumbar spine injury)
Depth of Drop	Chest close to the bar (increases range of motion by 20%)	Only perform half the range of motion (reduces training effectiveness)

3.Push-up Bar Maintenance and Storage

(1) Daily cleaning (after each use)

Surface treatment: Wipe the bar with a microfiber cloth and neutral detergent (do not use alcohol to corrode the anodized layer), and disinfect the silicone grip with 75% alcohol wipes (sterilizes and prevents slipping)
Rotary bearing: Use a dust gun to remove sweat particles (prevent them from entering the bearing balls)
Threaded interface: Clean the thread groove with a cotton swab (prevent metal fatigue fracture)

(2) Seasonal maintenance

Rust prevention in rainy season: Spray WD-40 anti-rust film on the aluminum alloy bar (forms a 0.1μm protective layer), and apply talcum powder to the silicone parts (to prevent mildew)
Winter brittle crack prevention: Store in a temperature ≥10℃ (low temperature causes the hardness of silicone to increase by 300%), and soak the grip in warm water for 5 minutes before use (to restore elasticity)
