Spring Resistance Arm Trainer for Chest and Arms

Use a spring-resistance bar for controlled upper-body training. Separate resistance options let you select a model for your strength level rather than assuming one bar adjusts across the full range.

Details

• Spring-resistance bar for arm and chest exercises.
• Current listed options: 20, 30, 40 and 50 kg.
• The source also mentions 60 kg, which is not present in the current option list.
• Portable design; no adjustment mechanism within one unit is established.

Select an appropriate resistance and follow the manufacturer's instructions. Keep the spring's return path away from the face and bystanders; do not release it abruptly.
