The most important question on any exercise is: what effect did this exercise have on my fitness? This is important as for a fit person low intensity training has less impact than for a less-fit person – the effect is personal. PulseOn tells you the effect of your training with Training Effect (TE). Training Effect measures workout’s impact on aerobic fitness at a scale of 1.0-5.0. Low intensity makes Training Effect accumulate slower and higher intensity faster. TE has five levels (1-5).
