Sleek, Adjustable Resistance for Every Fitness Level

The LEJIEYIN Twister Arm Exerciser’s core innovation lies in its:

• Adjustable Spring Tension: Turn the central knob to select from 5 resistance levels—ranging from 10 lbs for beginners to 50 lbs for advanced users—allowing progressive overload without extra equipment. 
• Ergonomic Handles: 6″ soft-touch grips reduce hand fatigue and prevent slipping during rapid rotations or isometric holds. 
• Compact, Foldable Frame: Collapses to under 12″×4″×2″ for easy storage in a drawer or gym bag—perfect for tight apartments or travel. 
• Dual-Axis Twisting Mechanism: 360° rotation engages biceps, triceps, deltoids, forearms, and core obliques in a single fluid movement. 

By combining upper-body torque and core stabilization, the twister simulator elevates simple arm-curl motions into multi-muscle, calorie-burning exercises.

Setup & First Twists: Ready in 60 Seconds

No tools or assembly are required—simply:

1. Unfold the Frame: Pop open the two-piece aluminum rails until they click into place. 
2. Adjust Tension Knob: Rotate to your starting resistance setting (level 1 for beginners). 
3. Grip Handles Firmly: Stand with feet shoulder-width apart, bend knees slightly, and hold each end of the device at chest height. 
4. Begin Twisting: Rotate the device clockwise and counterclockwise in controlled 2-second beats. 

Within one minute, you’re in motion—no bench, no bands, no barbell clutter.

Safety & Form: Train Smart, Avoid Strain

To prevent injury and maximize results:

• Maintain Neutral Spine: Keep shoulders back and chest lifted; avoid hunching. 
• Bend Knees Slightly: Relieve lower-back tension and improve balance. 
• Control Rotation: Twisting too fast can shock shoulders—aim for 2-second concentric, 2-second eccentric tempo. 
• Warm Up Thoroughly: Include arm circles, band pull-aparts, and cat-cow stretches before heavy twister work. 

By adhering to proper form cues, you’ll sculpt lean muscle rather than overstrain joints.

Durability & Materials: Built to Last

LEJIEYIN’s premium build quality ensures long-term performance:

• Anodized Aluminum Rails: Corrosion-resistant, lightweight, and robust. 
• Heavy-Duty Steel Springs: Rated for 10,000+ full-stroke cycles without fatigue. 
• Textured, Non-Slip Grips: Durable EVA foam stands up to sweat and frequent use. 
• Welded Joints & Reinforced Knob Housing: Prevent loosening under load, ensuring consistent resistance levels. 

With normal care, expect this twister exerciser to remain your go-to for years of at-home training.

Maintenance: Quick Clean & Lubrication

Keep your LEJIEYIN Twister in prime condition:

1. Wipe Down After Use: Use a damp cloth to remove sweat and dust from rails and handles. 
2. Lubricate Spring Assembly: Every 100 sessions, apply a few drops of silicone lubricant to the central spring housing. 
3. Inspect for Wear: Monthly check the spring tension knob and handle grips—replace EVA grips if cracked. 
4. Store Indoors: Protect from moisture and extreme temperatures to preserve spring integrity. 

These simple steps maintain smooth rotation and reliable resistance.
