It's best to place your device with a camera at a low height. A table, couch, or chair will work well.
If you are using a laptop, It would be easier to see the trainer. You will just have to do couple adjustments. Start by positioning it to capture your upper body for the beginning of the workout. When the trainer moves to floor exercises, tilt the camera slightly forward to ensure you are fully visible while sitting and lying down.
If you are using a phone, it will be easier to fit your whole body in the frame, but the small screen might make it difficult to see the trainer. You may need to move closer to view the technique for new exercises.
We recommend using a laptop for home workouts and a phone for gym and outdoor workouts, but feel free to try connecting with different devices to see which setup is most comfortable for you.
