1. A wearable device for monitoring physical activity of a user, the wearable device being reversibly attachable to a chest strap and an arm strap, the wearable device comprising:
an ECG sensor operable to collect ECG measurements of the user only when the wearable device is attached to the user's chest by the chest strap;
a PPG sensor operable to collect PPG measurements of the user when the wearable device is attached to the user's arm or wrist by the arm strap; and
control circuitry in communication with the ECG sensor and the PPG sensor, wherein the control circuitry is operable to receive input to switch the wearable device between an ECG only mode and a PPG only mode, wherein:
in the ECG only mode, the control circuitry is configured to control the ECG sensor to collect ECG measurements and PPG measurements are not collected by the PPG sensor; and
in the PPG only mode, the control circuitry is configured to control the PPG sensor to initiate PPG measurements and ECG measurements are not collected by the ECG sensor.
