FitQuest measures your heart rate through the multifunctional handles. This is more convenient than using a heart rate monitor, especially if you don’t own one. However, measuring your ECG through your hands is more difficult than using electrodes close to your heart. The biggest problem is the electrical signals (EMG) generated by the muscles in your arms. This so called noise can interfere with the small ECG signals that we want to measure.
Therefore, to obtain the best results, try not to tense the muscles in your upper body, whilst ensuring full hand contact with the integrated electrodes in the handles.
The single most important factor to obtaining a good result is to ensure that you grab the handles as soon as you finish the step test so that your heart has not had any time to recover.
