If the treadmill in the gym makes a lot of noise, it will affect the exercise experience of other bodybuilders and cause uncomfortable feelings for themselves. Here are some possible solutions:

1. Check whether the equipment is installed correctly: there may be loose screws or nuts in the area in front or under the treadmill, which should be tightened.

2. Check whether the ground is flat: If the treadmill is placed on the uneven ground, it may cause the treadmill to swing or swing, resulting in noise. Try to move the treadmill to a flat ground.

3. Anti-vibration pad: Using special anti-vibration pad can effectively absorb the vibration and noise of the treadmill, thus reducing the influence of noise.

4. Replace parts: check whether the parts of the treadmill are damaged or worn, and replace them if necessary.

5. Maintenance of the treadmill: Clean and lubricate the treadmill regularly to ensure its normal operation. Please follow the instructions.

If the problem cannot be solved in any way, it is recommended to contact the treadmill supplier or manufacturer for further investigation and maintenance.
