@rahulganatra and @Tungcaohn Welcome to the Community. Thanks for the details mentioned. 

I would like you to make sure you've followed these tips to improve your heart rate reading: 

• Wear your Fitbit device on top of your wrist, and make sure the back of the device is in contact with your skin.
• When you’re not exercising, wear your device a finger’s width above your wrist bone.
• During a workout, experiment with wearing the device higher on your wrist (2 finger widths) for an improved fit. Many exercises such as bike riding or weight lifting cause you to bend your wrist frequently, which could interfere with the heart-rate signal if the watch is lower on your wrist. 
• Consider tightening your wristband before a workout and loosening it when you’re done. The wristband should be snug but not constricting (a tight wristband restricts blood flow, potentially affecting the heart-rate signal). 

I'll be around if you have any additional questions.
