The most common mistake with planking is that the hips are often hanging too low. When it comes to bodyweight exercises like the plank, having good form is the most important factor that leads to faster results. Our app will tell you if you are truly planking correctly.

Planking is the perfect exercise to strengthen the core and to get shredded abs.

Planking at least once every day will provide a ton of health benefits.

Instructions:
1. Press CALIBRATE and place the phone on your back face up with the longer side parallel to your body
2. Keep a perfect plank for 5 seconds while your phone is calibrating
3. Once calibration is finished you can begin planking (you only need to calibrate once)
4. Press START PLANK and place the phone on your back again to begin planking
5. If the phone alarm sounds, it means your hips are either too high or too low
6. The timer will stop if you are doing the plank incorrectly and will continue once you are back in the correct position
7. Try to aim for 1 min 30 secs
