User Tips
- Start Slow: If you are new to massage guns, begin with the lowest speed setting and gradually increase as your muscles adapt.
- Hydrate: Drink plenty of water before and after your massage session to help flush out toxins released from your muscles.
- Listen to Your Body: Do not apply excessive pressure or massage directly over bones, joints, or sensitive areas. If you feel pain, reduce intensity or stop use.
- Warm-up and Cool-down: Use lower speeds for warm-up before exercise and higher speeds for cool-down and recovery afterward.
- Consistency is Key: Regular, short massage sessions can be more beneficial than infrequent, long ones.
