The present document discloses a computer-implemented method for providing training guidance in connection with a physical exercise, comprising: measuring, by using a heart activity sensor, heart activity of a user during a physical exercise； measuring, by using a bioimpedance measurement sensor, bioimpedance of the user during the physical exercise； computing, by a processing circuitry, a stroke volume from the bioimpedance synchronized to a cardiac cycle of the user by using the measured heart activity； computing, by the processing circuitry, training intensity by using at least the computed the stroke volume； comparing, by the processing circuitry, the training intensity with at least one threshold and outputting at least one training guidance instruction on the basis of the comparison.
