4. Setup and Assembly
The barbell bar is designed in a 3-piece threaded structure for easy assembly and storage. Follow these steps to prepare your barbell for use:
- Assemble the Barbell Bar: Carefully screw the three sections of the barbell bar together. Ensure they are tightly secured to form a single, stable bar.
- Select Weight Plates: Choose the desired weight plates (3 lbs, 11 lbs, 22 lbs, 33 lbs) to achieve your target weight.
- Load Weight Plates: Slide the selected weight plates onto both ends of the barbell bar. Distribute the weight evenly on each side for balance.
- Secure with Locking Clips: Once the desired weight plates are loaded, screw the locking clips onto the threaded ends of the bar, pressing them firmly against the outermost weight plates. Tighten them securely to prevent any movement or rotation of the plates during exercise.

5. Operating Instructions

5.1. Adjusting Weight
To adjust the weight, unscrew the locking clips, remove or add the desired weight plates, and then re-secure the locking clips tightly. Always ensure equal weight distribution on both sides of the bar.
5.2. Exercise Examples
This barbell set can be used for a wide range of exercises targeting different muscle groups:
- Squats: Targets glutes, quadriceps, and hamstrings. Place the barbell across your upper back, maintaining a straight back and controlled descent.
- Bench Press: Targets chest, shoulders, and triceps. Lie on a flat bench, grip the bar slightly wider than shoulder-width, and lower the bar to your chest before pressing it back up.
- Deadlifts: Targets back, glutes, hamstrings, and forearms. Stand with feet hip-width apart, bend at the hips and knees to grip the bar, then lift by extending your hips and knees, keeping your back straight.
- Overhead Press: Targets shoulders and triceps. Press the barbell from shoulder height directly overhead.
- Bent-Over Rows: Targets back muscles. Bend at the hips with a slight knee bend, keeping your back straight, and pull the barbell towards your abdomen.
